Felix Baumgartner (born 20 April 1969 in Salzburg, Austria) is an Austrian skydiver and a BASE jumper. He is renowned for the particularly dangerous nature of the stunts he has performed during his career. Baumgartner spent time in the Austrian military where he practiced parachute jumping, including training to land on small target zones.

He was born on 20 April 1969 in Salzburg, Austria.

In 1999 he claimed the world record for the highest parachute jump from a building when he jumped from the Petronas Towers in Kuala Lumpur, Malaysia.

On 31 July 2003, Baumgartner became the first person to skydive across the English Channel using a specially made fibre wing.

Baumgartner set the world record for the lowest BASE jump ever, from the hand of the Christ the Redeemer statue in Rio de Janeiro.

He became the first person to BASE jump from the completed Millau Viaduct in France on 27 June 2004^{[citation needed]} and the first person to sky dive onto, then BASE jump from, the Turning Torso building in Malmö, Sweden on 18 August 2006.

Tyler Bradt (born June 2, 1986) is an American whitewater kayaker known for kayaking Palouse Falls.

Born and raised in Stevensville, Montana, Tyler Bradt was first introduced to kayaking at only six years of age by his father, Bill Bradt. Tyler's skills seemed to be above average as he kayaked class five rapids only six years later at the age of twelve. By age fifteen, he was a kayaking prodigy, receiving national recognition for his abilities. In July of 2001, Tyler was invited to kayak rapids in Norway. While on this trip, Tyler had a near death experience when he was flipped and pinned up against a rock under the force of the water. To this day he still calls it "the closest call he's ever had". Tyler has appeared in several films, holds sponsors from NRS, KAVU, Smith, Dagger, At Paddle, Tribe, and Voke Tab. He has gone on kayaking expeditions and holds the record for the highest waterfall kayaked at 186 ft.

On April 21, 2009, Bradt successfully kayaked Palouse Falls in Washington state. At an estimated 186 feet (57 m), this made Bradt's descent a world record, breaking the previous record set by a Brazilian kayaker named Pedro Oliva who ran the 127-foot (39 m) Salto Belo of the Rio Sacre just a month before. In turn, Oliva's descent of Salto Belo broke Bradt's previous record of 107 feet (33 m) from 2007 over Alexandra Falls on the Hay River in the Northwest Territories. Bradt's plunge attracted media attention since the Palouse Falls are 17 feet (5.2 m) taller than Niagara Falls. His media agent sold both pictures and video of Bradt's descent to Sports Illustrated. On May 18, 2009, the first published photos appeared in the magazine along with video footage on SI's website. Bradt and kayaker/film maker/friend Rush Sturges used footage of the plunge in their 2010 collaborative film, Dream Result.
