While we have our “extreme” athletes these days, back in the 1920s people just did insane things for fun. Proof of that fact is contained in this video of a woman named Gladys Ingle, who was a member of a famous LA-based stunt flying troupe called the 13 Black Cats. This video shows Ingle swapping a wheel onto an ancient biplane while the plane is thousands of feet off the ground.

Spoiler alert: She does not die in the process but your heart may stop a couple times.

The level of courage and well, sheer balls exhibited here is unfathomable. From the move where she climbs off of the plan that brought her up onto the plane that is missing a wheel to the active climbing down onto the landing gear to install the wheel, it is all amazing. The best part is that during this era of motion picture making, camera tricks were non-existant. Hell, the “camera trick” was turning the thing on!

Get ready to watch a killer video with a pucker factory of 10 !
