Mistel
Mistel (German, 'mistletoe', a parasitic plant) was the larger, unmanned component of a composite aircraft configuration developed in Germany during the later stages of World War II. The composite comprised a small piloted control aircraft mounted above a large explosives-carrying drone, the Mistel, and as a whole was referred to as the Huckepack ('Piggyback'), also known as the Beethoven-Gerät ('Beethoven Device') or Vati und Sohn ('Daddy and Son'). The most successful of these used a modified Junkers Ju 88 bomber as the Mistel, with the entire nose-located crew compartment replaced by a specially designed nose filled with a large load of explosives, formed into a shaped charge.
