A flight suit is a full body garment, worn while flying aircraft such as military airplanes, gliders and helicopters. These suits are generally made to keep the wearer warm, as well as being practical (plenty of pockets), and durable (including fire retardant). Its appearance is usually similar to a jumpsuit. A military flight suit may also show rank insignia. It is sometimes used as a combat uniform in Close Quarters Battle or Visit, Board, Search, and Seizure situations, for its practicality.

As aviation developed in unheated open cockpits, the need for warm clothing quickly became apparent, as did the need for multiple pockets with closures of buttons, snaps, or zippers to prevent loss of articles during maneuvers. Various types of flight jackets and pants coverings were developed and, during World War I, leather two-piece outfits were common among pilots to ward off the chill caused by propwash and the cold of low-oxygen high altitude flying. Leather quickly became the preferred material due to its durability and the protection it offered against flying debris such as insect strikes during climb-outs and landings, and oil thrown off by the simple rotary and inline motors of the time. Australian aviator Frederick Sidney Cotton's experience with high level and low-temperature flying led Cotton in 1917 to develop the revolutionary new "Sidcot" suit, a flying suit which solved the problem pilots had in keeping warm in the cockpit. This flying suit, with improvements, was widely used by the RAF until the 1950s.

Jeb Corliss (born March 25, 1976 near Santa Fe, New Mexico) is a professional skydiver and BASE jumper. He has jumped from sites including Paris' Eiffel Tower, Seattle's Space Needle, and the Petronas Twin Towers in Kuala Lumpur, Malaysia.

Jeb Corliss is co-founder of 3 Triple 7, a clothing label.

He was also the original host of the Discovery Channel series Stunt Junkies, appearing in 13 episodes, but was fired by Discovery as a result of his arrest (below).

On September 25, 2011 Corliss jumped out of a helicopter at 6,000 feet and glided through a 100-ft wide archway in Tianmen Mountain in Zhangjiajie, Hunan Province, China, landing with a parachute on a nearby bridge.

In April 2006, Jeb Corliss attempted to BASE jump off the observation deck of the Empire State Building, while wearing a camera, but was restrained by building security and arrested by the NYPD. As a result, Corliss received three years probation and 100 hours community service, which was at one point overturned by a Manhattan state judge on the basis that Corliss "was experienced and careful enough to jump off a building without endangering his own life or anyone else’s". This sentence was affirmed in January 2009. Corliss was later permanently banned from setting foot in the Empire State Building.

Roberta Mancino is an Italian skydiver, BASE jumper, wingsuit flyer and international model. She has participated in more than 7,000 skydives and won several awards and world records. She has gone on four skydives while completely naked, and on five occasions her parachute did not open in mid-jump. In 2010, Mancino was named the World's Sexiest Female Athlete by the magazine Men's Fitness.

Born in Italy, Mancino was 16 when she did her first modeling work for a magazine. She started skydiving in October 2001. Mancino convinced her best friend, a skydiver, to take her on a jump even though he encouraged her not to because it was too dangerous. She began to take it more seriously as a profession when people started asking her to coach them. Eventually, Mancino started participating in international competitions.

She regularly trains at the Skyventure XP Paraclete in North Carolina. Her parachute has malfunctioned five times though she was able to use the reserve. She has also made four jumps while completely naked for magazine photo shoots. In 2008, Mancino appeared on the Italian television program Le Iene with Marco Berry, jumping topless and demonstrating her freeflying and sit flying skills. Mancino met her boyfriend BASE jumper Jeb Corliss, in 2009 after he learned about her jumps and arranged to meet her. In 2009, after having made about 5,500 skydives, Mancino started BASE jumping along with Corliss. She performed in 115 BASE jumps (35 with wingsuit) between August 2009 and September 2011. Also inspired by Corliss, she began wingsuit flying, which involves jumping from an aircraft wearing a jumpsuit with webbed wings similar to a flying squirrel. This led to proximity flying, which is the flying of a wingsuit in close proximity to cliffs and trees during the flight, the jumper then deploys their parachute once they have moved a safe distance away from any hazards (similar to BASE jumping in this respect).
