Your Sunday Morning Jet Noise

A test run of an engine from a V-1 (or JB-2 "Loon")



The key bit of information in a V-1 attack was to hear the Doodlebug pass by. If, on the other hand, you heard it approaching and the engine cut out, then you knew the beast was diving. The engine's quitting was a design defect and the Germans eventually fixed it, eliminating the attack warning.

The Germans had plans to build fighters using pulse-jet engines, but as the Argus 014 engine reportedly had a TBO of about one hour, those airplanes would have likely functioned almost as single-use aircraft.
