Ju-87 Stuka.

If ever there was to be an effective weapon that could be termed as being successful as well as deadly, it
would have to be the Junkers Ju-87, known to Germans as the "Sturzkampfbomber, and better known
to the English as a dive-bomber or better still a "Stuka". Some aircraft have a very specific place in
history, and in no case is this more true than for the German Junkers Ju-87 Stuka dive bomber. This
was one of Germany's famed "Butcher Birds". Although the Stuka was ugly, slow, un-maneuverable,
under-armed, already considered obsolete at the outbreak of WWII, and referred to by those who flew
it as "The Flying Coffin", it was the preferred mount of Hans-Ulrich Rudel, the most highly decorated
German serviceman of World War II. Although there were 5,700 Stukas built only 2 remain and both of
those are in museums.
