5 Insane Escapes Attempts That Worked

At noon of 8 February 1945, as the ten Soviet POWs, including Devyataev, were at work on the runway, one of the work gang, Ivan Krivonogov picked up a crowbar and killed their guard. Another prisoner, Peter Kutergun, quickly stripped off the guard's uniform and slipped it on. The work gang, led by the "guard", managed to unobtrusively take over the camp commandant's He 111 H22 bomberand fly from the island. Devyataev piloted the aircraft. The Germans tried to intercept the bomber but without success. The aircraft was damaged by the Soviet air defences but managed to land in Soviet-held territory. The escapees provided important information about the German missile program, especially about the V-1 and V-2.
