Oshkosh midair  

A fixed wing buddy of mine that was at the event told me a witness wrote up the account as follows:

“"There were two gyro copters (ELA Eclipse 10s) who have been hot-dogging the Ultralight flight pattern all week, doing things like crossing the threshold at 200 ft then spiraling down to a short landing. They were warned several times, to no avail. This afternoon, one of them was following a black Rotorway 162F (who was flying a normal rotor-craft pattern) but about 100ft higher. He did his spiral trick and slammed right into the chopper turning final. Killed the chopper pilot and injured his own pax. “
