Apparently, this is just another day in the lives of the Werth brothers. David Werth, a motorcycle stunt racer, and his brother Billy, a stunt pilot, like to race each other down the runway. David rides his motorcycle while Billy rides his plane... upside down.
Yep, it's the 'ol "inverted tail grab" stunt.
The Werth Brothers' company, Greyout, puts on stunt shows around the country. This year they'll be traveling to St. Louis, Utah, Indiana, Michigan, Washington, Florida, Kentucky and few other states. You can also hire them to take you on an upside down aerial tour of your city.
Here's their latest stunt. The inverted tail grab.
