My roommate at embassy guard school was a Harrier ejection seat technician at Cherry Point. They called the Harriers “Dead Bugs” because when hovering, if one of the two Rolls-Royce engines malfunctions, the plane flips over like a dead bug.
The Harrier is a single engine aircraft with 4 nozzles that rotate. In earlier Harriers the nozzles individual controlled by the pilot which resulted in many dead bug incidents. This resulted in the AV-8B+ Model were a computer helped the pilot control the input of the nozzles and accident rates dropped.
