I remember when I was a kid watching a guy with a big RC Stearman bi-plane. The thing must have had at least a 3 foot wingspan. Snoopy was the pilot and he had a bomb bay with working doors that he used to drop a parachuter out of. As the plane was going along, I heard him mumble "oh s@%!". His fingers were moving the control sticks all around but the plane wasn't responding. It nose dived into the ground from around 100 ft or so. The top wing blew off on impact and the nose of the plane was crushed clear up to the cockpit. He quietly walked over to his mangled plane, collected the parts and loaded everything into the back of his truck. He never said a thing as he drove away.
