U.S. officials are investigating the Selfridge Air Show accident on Sunday, in which stuntman Todd Green fell 200 feet from the airplane to his death.
Green's colleague Kyle Franklin told AP that Green was "very good at it" and performed it successfully "many, many times."
Green was attempting a stunt in which he stands on a small airplane and transfers himself to a helicopter by grabbing on the helicopter's skid. In the fatal accident, the stuntman appears to have lost his grip and then fallen to his death.
