The Bell X-1, originally designated XS-1, was a joint NACA-U.S. Army/US Air Force supersonic research project built by Bell Aircraft. Conceived in 1944 and designed and built over 1945, it eventually reached nearly 1,000 mph (1,609 km/h) in 1948. A derivative of this same design, the Bell X-1A, having greater fuel capacity and thus longer engine-burn time, exceeded 1,600 mph (2,574 km/h) in 1954.^[1] The X-1 was the first aircraft to exceed the speed of sound in controlled, level flight, and was the first of the so-called X-planes, an American series of experimental aircraft designated for testing of new technologies and usually kept highly secret.

Design and development[link]

XLR-11 rocket engine

On 16 March 1945, the United States Army Air Forces' Flight Test Division and the National Advisory Committee for Aeronautics (NACA) (now NASA) contracted Bell Aircraft to build three XS-1 (for "Experimental, Supersonic", later X-1) aircraft to obtain flight data on conditions in the transonic speed range.^[2]

The X-1 was in principle a "bullet with wings", its shape closely resembled the Browning .50-caliber (12.7 mm) machine gun bullet that was known to be stable in supersonic flight.^[3] The pattern shape was followed to the point of seating the pilot behind a sloped, framed window inside a confined cockpit in the nose, with no ejection seat. After the aircraft ran into compressibility problems in 1947, it was modified to feature a variable-incidence tailplane. An all-moving tail was developed by the British for the Miles M.52, and first saw actual transonic flight on the Bell X-1 that allowed it to pass through the sound barrier safely.

The rocket propulsion system was a four-chamber engine built by Reaction Motors, Inc., one of the first companies to build liquid-propellant rocket engines in America. It burned ethyl alcohol diluted with water and liquid oxygen. The thrust could be changed in 1,500 lbf (6,700 N) increments by firing one or more of the chambers. The fuel and oxygen tanks for the first two X-1 engines were pressurized with nitrogen and the rest with steam-driven turbopumps. The all-important fuel turbopumps, necessary to raise the chamber pressure and thrust, while lightening the engine, were built by Robert Goddard who was under Navy contract to provide jet-assisted takeoff rockets.^[4][5]

Operational history[link]

Bell Aircraft Chief Test Pilot, Jack Woolams became the first to fly the XS-1, in a glide flight over Pinecastle Army Airfield, in Florida, on 25 January 1946. Woolams would complete nine additional glide flights over Pinecastle before March 1946, when the #1 aircraft was returned to Bell for modifications in anticipation of the powered flight tests, planned for Muroc Army Air Field (now Edwards Air Force Base) in California.^[6] Following Woolams' death on 30 August 1946, Chalmers "Slick" Goodlin was the primary Bell Aircraft test pilot of X-1-1 (serial 46-062). He made 26 successful flights in both of the X-1 aircraft from September 1946 until June 1947.

The Army Air Force was unhappy with the cautious pace of flight envelope expansion and Bell Aircraft's flight test contract for aircraft #46-062 was terminated and was taken over by the Army Air Force Flight Test Division on 24 June after months of negotiation. Goodlin had demanded a US$150,000 bonus for breaking the sound barrier.^[7][8][9] Flight tests of the X-1-2 (serial 46-063) would be conducted by NACA to provide design data for later production high-performance aircraft.

Mach 1 flight[link]

Chuck Yeager in front of the X-1 he christened Glamorous Glennis

On 14 October 1947, just under a month after the United States Air Force had been created as a separate service, the tests culminated in the first manned supersonic flight, piloted by Air Force Captain Charles "Chuck" Yeager in aircraft #46-062, which he had christened Glamorous Glennis after his wife. The rocket-powered aircraft was launched from the bomb bay of a specially modified B-29 and glided to a landing on a runway. XS-1 flight number 50 is the first one where the X-1 recorded supersonic flight, at Mach 1.06 (361 m/s, 1,299 km/h, 807.2 mph) peak speed.^[1]

As a result of the X-1's initial supersonic flight, the National Aeronautics Association voted its 1948 Collier Trophy to be shared by the three main participants in the program. Honored at the White House by President Harry S. Truman were Larry Bell for Bell Aircraft, Captain Yeager for piloting the flights, and John Stack for the NACA contributions.

The story of Yeager’s 14 October flight was leaked to a reporter from Aviation Week, and The Los Angeles Times featured the story as headline news in their 22 December issue. The magazine story was released 20 December. The Air Force threatened legal action against the journalists who revealed the story, but none was ever taken.^[10]

On 5 January 1949, Yeager used Aircraft #46-062 to carry out the only conventional (runway) take off performed during the X-1 program, reaching 23,000 ft (7,000 m) in 90 seconds.^[11]

Legacy[link]

The research techniques used in the X-1 program became the pattern for all subsequent X-craft projects. The NACA X-1 procedures and personnel also helped lay the foundation of America's space program in the 1960s. The X-1 project defined and solidified the post-war cooperative union between U.S. military needs, industrial capabilities, and research facilities. The flight data collected by the NACA in the X-1 tests then proved invaluable to further US fighter design throughout the latter half of the 20th century.

Variants[link]

Later variants of the X-1 were built to test different aspects of supersonic flight; one of these, the X-1A, with Yeager at the controls, inadvertently demonstrated a very dangerous characteristic of fast (Mach 2 plus) supersonic flight: inertia coupling. Only Yeager's skills as an aviator prevented him from dying that day; later Mel Apt would die testing the Bell X-2 under similar circumstances.

X-1A[link]

X-1A.

Ordered by the Air Force on 2 April 1948, the X-1A (serial 48-1384) was intended to investigate aerodynamic phenomena at speeds above Mach 2 (681 m/s, 2,451 km/h) and altitudes greater than 90,000 ft (27 km), specifically focusing on dynamic stability and air loads. Longer and heavier than the original X-1, with a bubble canopy for better vision, the X-1A was powered by the same Reaction Motors XLR-11 rocket engine. The aircraft first flew, unpowered, on 14 February 1953 at Edwards AFB, with the first powered flight on 21 February. Both flights were piloted by Bell test pilot Jean "Skip" Ziegler.

After NACA started its high-speed testing with the Douglas Skyrocket, culminating in Scott Crossfield achieving Mach 2.005 on 20 November 1953, the Air Force started a series of tests with the X-1A, which the test pilot of the series, Chuck Yeager, named "Operation NACA Weep". These culminated on 12 December 1953, when Yeager achieved an altitude of 74,700 feet (22,800 m) and a new air speed record of Mach 2.44 (equal to 1620 mph, 724.5 m/s, 2608 km/h at that altitude). Unlike Crossfield in the Skyrocket, Yeager achieved that in level flight. Shortly after, the aircraft spun out of control, due to the then not yet understood phenomenon of inertia coupling. The X-1A dropped from maximum altitude to 25,000 feet (7,600 m), exposing the pilot to accelerations of up to 8g, during which Yeager broke the canopy with his helmet before regaining control.^[12]

On 28 May 1954, Maj. Arthur W. Murray piloted the X-1A to a new record of 90,440 feet (27,570 m).^[13]

The aircraft was transferred to NACA in September 1954. Following modifications, including the installation of an ejection seat, the aircraft was lost on 8 August 1955 while being prepared for launch from the RB-50 mothership, becoming the first of many early X-planes that would be lost to explosions.^[2][14]

X-1B[link]

X-1B at the National Museum of the United States Air Force

The X-1B (serial 48-1385) was equipped with aerodynamic heating instrumentation for thermal research (over 300 thermal probes were installed on its surface). It was similar to the X-1A except for having a slightly different wing. The X-1B was used for high speed research by the US Air Force starting from October 1954 prior to being turned over to the NACA in January 1955. NACA continued to fly the aircraft until January 1958 when cracks in the fuel tanks forced its grounding. The X-1B completed a total of 27 flights. A notable achievement was the installation of a system of small reaction rockets used for directional control, making the X-1B the first aircraft to fly with this sophisticated control system, later used in the North American X-15. The X-1B is now at the National Museum of the United States Air Force, Wright-Patterson Air Force Base at Dayton, Ohio, where it is displayed in the Museum's Research & Development Hangar.

X-1C[link]

The X-1C (serial 48-1387)^[15] was intended to test armaments and munitions in the high transonic and supersonic flight regimes. It was canceled while still in the mock-up stage, as the birth of transonic and supersonic-capable aircraft like the North American F-86 Sabre and the North American F-100 Super Sabre eliminated the need for a dedicated experimental test platform.^[16]

X-1D[link]

The X-1D (serial 48-1386) was the first of the second generation of supersonic rocket planes. Flown from an EB-50A (s/n #46-006), it was to be used for heat transfer research. The X-1D was equipped with a new low-pressure fuel system and a slightly increased fuel capacity. There were also some minor changes to the avionics set.

On 24 July 1951, with Bell test pilot Jean "Skip" Ziegler at the controls, the X-1D was launched over Rogers Dry Lake, on what was to become the only successful flight of its career. The unpowered glide was completed after a nine-minute descent, but upon landing, the nose gear failed and the aircraft slid ungracefully to a stop. Repairs took several weeks to complete and a second flight was scheduled for mid-August. On 22 August 1951, the X-1D was lost in a fuel explosion during preparations for the first powered flight. The aircraft was destroyed upon impact after it was jettisoned from its EB-50A mothership.^[17]

X-1E[link]

Bell X-1-3, aircraft #46-064, being mated to the B-50 mothership for a captive flight test on 9 November 1951. While being de-fueled after this flight it exploded, destroying itself and the B-50, and seriously burning Joe Cannon. X-1-3 had only completed a single glide flight on 20 July.^[2]

The X-1E was the result of a reconstruction of the X-1-2 (serial 46-063), in order to pursue the goals originally set out for the X-1D and X-1-3 (serial 46-064), both lost in explosions in 1951. The cause of the mysterious explosions was finally traced to the use of Ulmer leather gaskets impregnated with tricresyl phosphate (TCP), a leather treatment, which was used in the liquid oxygen plumbing. TCP becomes unstable and explosive in the presence of pure oxygen and mechanical shock.^[18] This mistake cost two lives, caused injuries and lost several aircraft.^[19]

The X-1E, christened ‘Little Joe’, with pilot Joe Walker.

The changes included:

• A turbopump fuel feed system, which eliminated the high-pressure nitrogen fuel system used in '062 and '063. (Concerns about metal fatigue in the nitrogen fuel system resulted in the grounding of the X-1-2 after its 54th flight in its original configuration.)^[20]
• A re-profiled super-thin wing (3 ³⁄₈ inches at the root), based on the X-3 Stiletto wing profile, enabling the X-1E to reach Mach 2.
• A 'knife-edge' windscreen replaced the original greenhouse glazing, an upward-opening canopy replaced the fuselage-side hatch and allowed the inclusion of an ejection seat.
• The addition of 200 pressure ports for aerodynamic data, and 343 strain gauges to measure structural loads and aerodynamic heating along the wing and fuselage.^[20]

The X-1E first flew on 15 December 1955, a glide flight under the controls of USAF test pilot Joe Walker. Walker left the X-1E program in 1958, after 21 flights, attaining a maximum speed of Mach 2.21 (752 m/s, 2,704 km/h). NACA research pilot John B. McKay took his place in September 1958, completing five flights in pursuit of Mach 3 (1,021 m/s, 3,675 km/h) before the X-1E was permanently grounded following its 26th flight, in November 1958, due to the discovery of structural cracks in the fuel tank wall.

There are many people in history who are commonly appended with the phrase "the Great", or who were called that or an equivalent phrase in their own language. Other languages have their own suffixes such as e Bozorg and e azam in Persian and Urdu respectively.

In Persia, the title "the Great" at first seems to be a colloquial version of the Old Persian title "Great King". This title was first used by the conqueror Cyrus II of Persia.^[1]

The Persian title was inherited by Alexander III of Macedon (336–323 BC) when he conquered the Persian Empire, and the epithet "Great" eventually became personally associated with him. The first reference (in a comedy by Plautus)^[2] assumes that everyone knew who "Alexander the Great" was; however, there is no earlier evidence that Alexander III of Macedon was called "the Great".

The early Seleucid kings, who succeeded Alexander in Persia, used "Great King" in local documents, but the title was most notably used for Antiochus the Great (223–187 BC).

Later rulers and commanders began to use the epithet "the Great" as a personal name, like the Roman general Pompey. Others received the surname retrospectively, like the Carthaginian Hanno and the Indian emperor Ashoka the Great. Once the surname gained currency, it was also used as an honorific surname for people without political careers, like the philosopher Albert the Great.

As there are no objective criteria for "greatness", the persistence of later generations in using the designation greatly varies. For example, Louis XIV of France was often referred to as "The Great" in his lifetime but is rarely called such nowadays, while Frederick II of Prussia is still called "The Great". A later Hohenzollern - Wilhelm I - was often called "The Great" in the time of his grandson Wilhelm II, but rarely later.

David Michael Letterman (born April 12, 1947) is an American television host and comedian.^[1] He hosts the late night television talk show, Late Show with David Letterman, broadcast on CBS. Letterman has been a fixture on late night television since the 1982 debut of Late Night with David Letterman on NBC. Letterman recently surpassed friend and mentor Johnny Carson for having the longest late-night hosting career in the United States of America.^[4]

Letterman is also a television and film producer. His company Worldwide Pants produces his show as well as its network follow-up The Late Late Show with Craig Ferguson. Worldwide Pants has also produced several prime-time comedies, the most successful of which was Everybody Loves Raymond, currently in syndication.

In 1996, David Letterman was ranked #45 on TV Guide's 50 Greatest TV Stars of All Time.^[5]

Early life and career[link]

Letterman was born in Indianapolis, Indiana. His father, Harry Joseph Letterman (April 1915 – February 1973),^[6] was a florist of British descent; his mother Dorothy Letterman (née Hofert, now Dorothy Mengering), a Presbyterian church secretary of German descent, is an occasional figure on the show, usually at holidays and birthdays.

Letterman lived on the north side of Indianapolis (Broad Ripple area), not far from Speedway, IN, and the Indianapolis Motor Speedway, and he enjoyed collecting model cars, including racers.^[7] In 2000, he told an interviewer for Esquire that, while growing up, he admired his father's ability to tell jokes and be the life of the party. Harry Joseph Letterman survived a heart attack at age 36, when David was a young boy. The fear of losing his father was constantly with Letterman as he grew up.^[8] The elder Letterman died of a second heart attack^[9] at age 57.

Letterman attended his hometown's Broad Ripple High School at the same time as Marilyn Tucker (future wife of Dan Quayle) and worked as a stock boy at the local Atlas supermarket.^[10] According to the Ball State Daily News, he originally had wanted to attend Indiana University, but his grades weren't good enough, so he decided to attend Ball State University, in Muncie, Indiana.^[11] He is a member of the Sigma Chi Fraternity, and he graduated from what was then the Department of Radio and Television, in 1969. A self-described average student, Letterman endowed a scholarship for what he called "C students" at Ball State.^[12]

Though he registered for the draft and passed his physical after graduating from college, he was not drafted for service in Vietnam due to receiving a draft lottery number of 352 (out of 365).^[13]

Letterman began his broadcasting career as an announcer and newscaster at the college's student-run radio station—WBST—a 10-watt campus station which now is part of Indiana Public Radio.^[14] He was fired for treating classical music with irreverence.^[14]

Letterman then became involved with the founding of another campus station—WAGO-AM 570 (now WWHI, 91.3).^[15]

Letterman credits Paul Dixon—host of the Paul Dixon Show, a Cincinnati-based talk show also shown in Indianapolis while Letterman was growing up—for inspiring his choice of career:^[3]

"I was just out of college [in 1969], and I really didn't know what I wanted to do. And then all of a sudden I saw him doing it [on TV]. And I thought: That's really what I want to do!"

Weatherman[link]

Letterman began his career as a radio talk show host on WNTS (AM), and on Indianapolis television station WLWI (now called WTHR) as an anchor, and weatherman. He received some attention for his unpredictable on-air behavior, which included congratulating a tropical storm for being upgraded to a hurricane and predicting hail stones "the size of canned hams."^[16] He would also occasionally report the weather and the day's very high and low temps for fictitious cities ("Eight inches of snow in Bingree and surrounding areas.") while on another occasion saying that a state border had been erased.^[17] ("From space you can see the border between Indiana and Ohio has been erased. I'm not in favor of this.") He also starred in a local kiddie show, made wisecracks as host of a late night TV show called "Freeze-Dried Movies" (he once acted out a scene from "Godzilla" using plastic dinosaurs),^[18] and hosted a talk show that aired early on Saturday mornings called "Clover Power,"^[19] in which he interviewed 4-H members about their projects.^[20]

In 1971, Letterman appeared as a pit road reporter for ABC Sports' tape-delayed coverage of the Indianapolis 500.^[21] David initially is introduced as Chris Economaki in his job as a corner reporter. Letterman interviews Mario Andretti who has just crashed out of the race and asks him a question about traffic on the course.

Move to Los Angeles[link]

In 1975, encouraged by his then-wife Michelle and several of his Sigma Chi fraternity brothers, Letterman moved to Los Angeles, California, with hope of becoming a comedy writer.^[22] He started off by writing material for comedian Jimmie Walker.^[23] He also began performing stand-up comedy at The Comedy Store, a proving ground for unknown comics.

In the summer of 1977, Letterman was a writer and regular on the six-week summer series The Starland Vocal Band Show, broadcast on CBS.^[24] He hosted a 1977 pilot for a game show entitled The Riddlers^[25][26] that was never picked up and co-starred in the Barry Levinson-produced comedy special Peeping Times that aired in January 1978. Later that year, Letterman was a cast member on Mary Tyler Moore's variety show, Mary.^[27] Letterman made a guest appearance on Mork & Mindy (as a parody of EST leader Werner Erhard^[28]) and appearances on game shows such as The $20,000 Pyramid,^[29] The Gong Show, Password Plus^[30] and Liar's Club, as well as talk shows such as The Mike Douglas Show.^[31] He was also screen tested for the lead role in the 1980 film Airplane!, a role that eventually went to Robert Hays.^[32]

His dry, sarcastic humor caught the attention of scouts for The Tonight Show Starring Johnny Carson, and Letterman was soon a regular guest on the show. Letterman became a favorite of Carson's and was a regular guest host for the show beginning in 1978. Letterman credits Carson as the person who influenced his career the most.^[2]

NBC[link]

Morning show[link]

On June 23, 1980, Letterman was given his own morning comedy show on NBC, The David Letterman Show. It was originally 90 minutes long, but was shortened to 60 minutes in August 1980.^[33] The show was a critical success, winning two Emmy Awards, but was a ratings disappointment and was canceled in October 1980.

[edit] Late Night with David Letterman

NBC kept Letterman under contract to try him in a different time slot. Late Night with David Letterman debuted February 1, 1982; the first guest on the first show was Bill Murray.^[34] Murray also guested on January 31, 2012 – 30 years later. The show ran Monday through Thursday at 12:30 a.m. Eastern Time, immediately following The Tonight Show Starring Johnny Carson (a Friday night broadcast was added in June 1987). It was seen as being edgy and unpredictable, and soon developed a cult following (particularly among college students). Letterman's reputation as an acerbic interviewer was borne out in verbal sparring matches with Cher^[35] (who even called him an asshole on the show), Shirley MacLaine,^[36] Charles Grodin, and Madonna. The show also featured comedy segments and running characters, in a style heavily influenced by the 1950s and 1960s programs of Steve Allen.^[37] Although Ernie Kovacs is often cited as an influence on the show,^[38] Letterman has denied this.^[2]

The show often featured quirky, genre-mocking regular features, including "Stupid Pet Tricks^[39] ", dropping various objects off the roof of a five-story building,^[40] demonstrations of unorthodox clothing (such as suits made of Alka-Seltzer,^[41] Velcro^[42] and suet), a recurring Top 10 list, the Monkey-Cam^[43] (and the Audience Cam), and a facetious letter-answering segment.^[44] The Top 10 list, several "Film[s] by My Dog Bob" in which a camera was mounted on Letterman's own dog^[45] (often with comic results), Stupid Human Tricks,^[46] Small Town News,^[47] and Stupid Pet Tricks^[48] (which had its origins on Letterman's morning show) all eventually moved with Letterman to CBS.

Other memorable moments included Letterman using a bullhorn to interrupt a live interview on The Today Show, announcing that he was the NBC president while not wearing any pants; interrupting Al Roker on WNBC-TV's broadcast of Live at Five by walking into their studio (which occupied the same floor of 30 Rockefeller Plaza as Letterman's studio); and staging "elevator races", complete with commentary by NBC Sports' Bob Costas. In one infamous appearance, in 1982, Andy Kaufman (who was already wearing a neck brace) appeared to be slapped and knocked to the ground by professional wrestler Jerry Lawler (though Lawler and Kaufman's friend Bob Zmuda later revealed that the event was staged.)^[49] In another memorable exchange, sex expert Dr. Ruth Westheimer included cucumbers in a list of handy sex objects that women could find at home. The following night, guest Ted Koppel asked Letterman "May I insert something here?" and Dave responded "OK, as long as it's not a cucumber."^{[citation needed]}

[edit] Late Show with David Letterman

The Ed Sullivan Theater, where Late Show with David Letterman is recorded

In 1992, Johnny Carson retired, and many fans believed that Letterman would become host of The Tonight Show. When NBC instead gave the job to Jay Leno, Letterman departed NBC to host his own late-night show on CBS, opposite The Tonight Show at 11:30 p.m., called the Late Show with David Letterman. The new show debuted on August 30, 1993 and was taped at the historic Ed Sullivan Theater, where Ed Sullivan taped his eponymous variety series from 1948 to 1971. For Letterman's arrival, CBS spent $8 million in renovations.^[50] In addition to that cost, CBS also signed Letterman to a lucrative three-year, $14 million/year contract,^[51] doubling his Late Night salary. The total cost for everything (renovations, negotiation right paid to NBC, signing Letterman, announcer Bill Wendell, Shaffer, the writers and the band) was over $140 million.

But while the expectation was that Letterman would retain his unique style and sense of humor with the move, Late Show was not an exact replica of his old NBC program. Recognizing the more formal mood (and wider audience) of his new time slot and studio, Letterman eschewed his trademark blazer with khaki pants and white sneakers wardrobe combination in favor of expensive shoes, tailored suits and light-colored socks. The monologue was lengthened and Paul Shaffer and the "World's Most Dangerous Band" followed Letterman to CBS, but they added a brass section and were rebranded the "CBS Orchestra" as a short monologue and a small band were mandated by Carson while Letterman occupied the 12:30 slot. Additionally, because of intellectual property disagreements, Letterman was unable to import many of his Late Night segments verbatim,^[52] but he sidestepped this problem by simply renaming them (the "Top Ten List" became the "Late Show Top Ten", "Viewer Mail" became the "CBS Mailbag", etc.)

Popularity[link]

The main competitor of The Late Show is NBC's The Tonight Show, which was hosted by Jay Leno for nearly 16 years, but from June 1, 2009, to January 22, 2010, was hosted by Conan O'Brien. In 1993 and 1994, The Late Show consistently gained higher ratings than The Tonight Show. But in 1995, ratings dipped and Leno's show consistently beat Letterman's in the ratings from the time that Hugh Grant came on Leno's show after Grant's arrest for soliciting a prostitute.;^[53] Leno typically attracted about 5 million nightly viewers between 1999 and 2009. The Late Show lost nearly half its audience during its competition with Leno, attracting 7.1 million viewers nightly in its 1993–94 season and about 3.8 million per night as of Leno's departure in 2009.^[54] In the final months of his first stint as host of The Tonight Show, Leno beat Letterman in the ratings by a 1.3 million viewer margin (5.2 million to 3.9 million), and Nightline and The Late Show were virtually tied.^[55] Once O'Brien took over Tonight, however, Letterman closed the gap in the ratings.^[56][57][58] O'Brien initially drove the median age of Tonight Show viewers from 55 to 45, with most older viewers opting to watch The Late Show instead.^[59]

Following Leno's return to The Tonight Show, however, Leno has regained his lead.^[60]

Letterman's shows have garnered both critical and industry praise, receiving 67 Emmy Award nominations, winning 12 times in his first 20 years in late night television. From 1993–2009, Letterman ranked higher than Leno in the annual Harris Poll of Nation's Favorite TV Personality 12 times.^[61] For example, in 2003 and 2004 Letterman ranked second in that poll, behind only Oprah Winfrey, a year that Leno was ranked fifth.^[62] Leno was higher than Letterman on that poll three times during the same period, in 1998, 2007, and 2008.^[61]

Hosting the Academy Awards[link]

On March 27, 1995, Letterman acted as the host for the 67th Academy Awards ceremony. Critics blasted^[63] Letterman for what they deemed a poor hosting of the Oscars, noting that his irreverent style undermined the traditional importance and glamor of the event.^{[citation needed]} In a joke about their unusual names (inspired by a similar joke by Woody Allen), he started off by introducing Uma Thurman to Oprah Winfrey, and then both of them to Keanu Reeves: "Oprah...Uma. Uma...Oprah," "Have you kids met Keanu?"^[64] This and many of his other jokes fell flat.^{[citation needed]} Although Letterman attracted the highest ratings to the annual telecast since 1983, many felt that the bad publicity garnered by Letterman's hosting caused a decline in the Late Show's ratings.^[65]

Letterman recycled the apparent debacle into a long-running gag. On his first show after the Oscars, he joked, "Looking back, I had no idea that thing was being televised." He lampooned his stint two years later, during Billy Crystal's opening Oscar skit, which also parodied the plane-crashing scenes from that year's chief nominated film, The English Patient.

For years afterward, Letterman recounted his hosting the Oscars, although the Academy of Motion Picture Arts and Sciences continued to hold Letterman in high regard and they had invited him to host the Oscars again.^[66][67] On September 7, 2010, he made an appearance on the premiere of the 14th season of The View, and confirmed that he had been considered for hosting again.

Heart surgery hiatus[link]

On January 14, 2000, a routine check-up revealed that an artery in Letterman's heart was severely obstructed. He was rushed to emergency surgery for a quintuple bypass.^[68]

During the initial weeks of his recovery, reruns of the Late Show were shown and introduced by friends of Letterman including Drew Barrymore,^[58] Ray Romano, Robin Williams, Bonnie Hunt, Megan Mullally, Bill Murray, Regis Philbin, Charles Grodin, Nathan Lane, Julia Roberts,^[58] Bruce Willis, Jerry Seinfeld, Martin Short, Steven Seagal, Hillary Rodham Clinton, Danny DeVito, Steve Martin, and Sarah Jessica Parker.

Subsequently, while still recovering from surgery, Letterman revived the late night tradition that had virtually disappeared on network television during the 1990s of 'guest hosts' by allowing Bill Cosby, Kathie Lee Gifford (recommended by Regis Philbin, who was asked first but had no time in his schedule), Dana Carvey, Janeane Garofalo, and others to host new episodes of The Late Show. Cosby—the show's first guest host—refused to sit at Letterman's desk out of respect, using the couch instead; Garofalo followed suit, utilizing a set of grade-school desks instead.

Upon his return to the show on February 21, 2000, Letterman brought all of the doctors and nurses on stage who had participated in his surgery and recovery (with extra teasing of a nurse who had given him bed baths—"This woman has seen me naked!"),^[69] including Dr. O. Wayne Isom and physician Louis Aronne, who frequently appears on the show. In a show of emotion, Letterman was nearly in tears as he thanked the health care team with the words "These are the people who saved my life!" The episode earned an Emmy nomination. For a number of episodes, Letterman continued to crack jokes about his bypass, including saying, "Bypass surgery: it's when doctors surgically create new blood flow to your heart. A bypass is what happened to me when I didn't get The Tonight Show! It's a whole different thing." In a later running gag he lobbied his home state of Indiana to rename the freeway circling Indianapolis (I-465) "The David Letterman Bypass." He also featured a montage of faux news coverage of his bypass surgery, which included a clip of Dave's heart for sale on the Home Shopping Network. Letterman became friends with his doctors and nurses. In 2008, a Rolling Stone interview stated "he hosted a doctor and nurse who'd helped perform the emergency quintuple-bypass heart surgery that saved his life in 2000. 'These are people who were complete strangers when they opened my chest,' he says. 'And now, eight years later, they're among my best friends.' "^[4]

Additionally, Letterman invited the band Foo Fighters to play "Everlong",^[70] introducing them as "my favorite band, playing my favorite song."^[71] During a later Foo Fighters appearance, Letterman said that Foo Fighters had been in the middle of a South American tour which they canceled to come play on his comeback episode.

Letterman again handed over the reins of the show to several guest hosts (including Bill Cosby, Brad Garrett, Elvis Costello, John McEnroe, Vince Vaughn, Will Ferrell, Bonnie Hunt, Luke Wilson and bandleader Paul Shaffer) in February 2003, when he was diagnosed with a severe case of shingles. Later that year, Letterman made regular use of guest hosts—including Tom Arnold and Kelsey Grammer—for new shows broadcast on Fridays. In March 2007, Adam Sandler—who had been scheduled to be the lead guest—served as a guest host while Letterman was ill with a stomach virus.^[72]

Re-signing with CBS[link]

In March 2002, as Letterman's contract with CBS neared expiration, ABC offered him the time slot for long-running news program Nightline with Ted Koppel. Letterman was interested as he believed he could never match Leno's ratings at CBS due to Letterman's complaint of weaker lead-ins from the network's late local news programs, but was reluctant to replace Koppel.^[73] Letterman addressed his decision to re-sign on the air, stating that he was content at CBS and that he had great respect for Koppel.

On December 4, 2006, CBS revealed that Letterman signed a new contract to host The Late Show with David Letterman through the fall of 2010. "I'm thrilled to be continuing on at CBS," said Letterman. "At my age you really don't want to have to learn a new commute."^[74] Letterman further joked about the subject by pulling up his right pants leg, revealing a tattoo, presumably temporary, of the ABC logo.

"Thirteen years ago, David Letterman put CBS late night on the map and in the process became one of the defining icons of our network," said Leslie Moonves, president and CEO of CBS Corporation. "His presence on our air is an ongoing source of pride, and the creativity and imagination that the Late Show puts forth every night is an ongoing display of the highest quality entertainment. We are truly honored that one of the most revered and talented entertainers of our time will continue to call CBS 'home.'"^[75]

According to a 2007 article in Forbes magazine, Letterman earned $40 million a year.^[76] A 2009 article in The New York Times, however, said his salary was estimated at $32 million per year.^[77] In June 2009, Letterman's Worldwide Pants and CBS reached agreement to continue the Late Show until at least August 2012. The previous contract had been set to expire in 2010, and the two-year extension is shorter than the typical three-year contract period negotiated in the past.^[77] Worldwide Pants agreed to lower its fee for the show, though it had remained a "solid moneymaker for CBS" under the previous contract.^[77]
