This airplane had flown for 27 days. The photo is of an early inflight refueling in 1935. This airplane, a Curtis Robin named Ole Miss, is in the Smithsonian National Air and Space Museum

This footage of various aerial, aquatic and rodeo stunts from the early 20th century no doubt took the breath away from audiences of its day. The classic air show stunts involving wing walkers, parachutes etc. are in fact very well staged and filmed, especially the wing walkers who allow their chutes to carry them off the wing platforms. And the plane which drifts to earth carried by a giant chute is something I've actually never seen before. A nice compilation, well worth the time it takes to watch it.

Exciting for it's time. This silent film is not clear probably due to age.

A compilation of stunt people, extreme sports people and natural disasters (yay volcanoes!) all compiled into one film! Some are of course more spectacular than others. Faves include man escaping a strait jacket while hanging upside down out of an airplane and those insane stunts when something goes wrong! Don't try this at home kids!
