Watch this amazing stunt pilot fly a helicopter upside-down

Chuck Aaron is a 63-year-old stunt helicopter pilot whose major trick is the ability to upend his bird.

Completely upside-down.

According to a profile of the man in Popular Mechanics, a helicopter's rotator blades would bend toward its skids when flying upside down. The blades would cut off the tail and the vehicle would return to Earth. Very quickly. And uncontrollably.

So how does Aaron do it?

He had assembled his own U.S. Army attack helicopter from spare parts when Red Bull came calling. They wanted to know if it were possible to configure a helo to fly upside down. His gut feeling was an instinct to stay alive and he gave them a firm no. But as he thought about it, he began to come up with modifications that just might work for that purpose.

It helps that Red Bull covered the tab. Aaron doesn't discuss the exact modifications he made, but you can see the results speak for themselves.
