When I was in the air force, a sergeant committed suicide by jumping in front of the propellor of a T-29 (an old 2 engine propeller plane) as it was going down the runway. It was a dark rainy night and this sergeant had caught his wife fooling around. He worked maintenance and had a pass to be on the flight line. The pilots saw the guy about a second before he hit the propellor. There wasn' t any big chunks left. The engines were at take off power.
