This German training film labeled as "TOP SECRET" from the E.d.L (Erprobungsstelle der Luftwaffe / Test Center of the Air Force) Karlshagen describes in detail the technique and handling of this completely new weapon system.
The V-1 flying bomb (German: Vergeltungswaffe)—also known to the Allies as the buzz bomb, or doodlebug, and in Germany as Kirschkern (cherrystone) or Maikäfer (maybug)—was an early pulsejet-powered cruise missile, the first production aircraft to use a pulsejet for power.
The V-1 was developed at Peenemünde Army Research Center by the Nazi German Luftwaffe during the Second World War. During initial development it was known by the codename "Cherry Stone".
The first of the so-called Vergeltungswaffen series designed for terror bombing of London, the V-1 was fired from launch facilities along the French (Pas-de-Calais) and Dutch coasts.
