Martin B-26B Marauder "Flak Bait"
Named after the pilot's dog, "Flak Bait" acquired more than 1,000 holes, had its hydraulic system shot out twice and its electrical system once, returned twice on one engine, and came back once with an engine on fire. By war's end, it had flown 202 bombing missions (including 2 on D-Day), more than any other American bomber over Europe.
