The Hoppicopter was designed by Horace Pentecost of Seattle, Washington during World War II as a replacement for paratroopers’ parachutes. Twin co-axial rotors were powered by a 20 hp engine.
A few test hops were made; however, relying on the pilots feet for landing gear was inherently dangerous. If the pilot stumbled on landing, the rotating rotors would quickly turn into thousands of lethal splinters.

Nice tiny tie with the wool plaid! And the crotch harness looks real comfortable.
sure beats being stuck in 520 traffic!! Why don’t people name their kids Horace anymore?
The crotch harness might not have been comfortable but it was undoubtedly more comfortable than getting hit with those, you know, thousands of lethal splinters.
Based on that Modern Mechanics post, I think that is Horace himself.
