This system was given this name following an accident in which Hoover was seriously injured, when both engines on his Shrike Commander failed during takeoff. Investigators found that the aircraft had just been fueled by line personnel who mistook the piston-engine Shrike for a similar turboprop model, filling the tanks with jet fuel instead of avgas (aviation gasoline). There was enough avgas in the fuel system for the aircraft to taxi to the runway and take off, but then the jet fuel was drawn into the engines, causing them to stop.
