During WW2, when project Aphrodite was in full swing.
(Aphrodite was an American "Mistel Project" But using old B-17s flown via radio control after the crew bailed out upon take off.)
One B-17 packed with explosives broke contact from it's handler aircraft. after numerous attempts to reestablish radio control failed, the handler aircraft turned home.
Allowing the explosive laden B-17 to fly until it exhuasted it's fuel and made a wheels up landing into a field in Germany.
Local Wermacht troops witnessed the landing and quickly surrounded the aircraft. They ordered the crew to evacuate the aircraft with thier hands up and surrender.
When they recived no reply, they opened fire......
The crater was 150' wide and 30' deep.
