actually the rotors are very low speed. gyrocopters rotate at 500 RPM, which is the same range as helicopters. but helicopter rotors are designed like a fan, where lift is generated by directing air downwards. If you look at a gyrocopter rotor it has the cross section of an airplane wing. lift is generated from the bournulli effect. ao if you stand under a gyrocopter you aren't blown away by the downwind.
Oh, OK. So if were to have crashed that machine into the group of school kids he flew past, it probably wouldn't have hurt anybody.
