Warsaw: Archaeologists have discovered the wreck of a US-made bomber flown by the Soviet Red Army in World War II, along with the remains of four crewmen killed when it crashed in southern Poland, private broadcaster TVN reported.

Only one man survived when the B-25 Mitchell was shot down by the German air force on January 19, 1945, a 23-year-old commander who parachuted out and was taken into German captivity.
