One well-known
B-25C of the 321st Bomb Group was nicknamed "Patches" because its crew chief painted all the plane's flak hole patches with high-visibility zinc chromate paint. By the end of the war, this aircraft had completed over 300 missions, was belly-landed half a dozen times, and sported over 400 patched holes. The airframe was so bent that straight-and-level flight required 8° of left aileron trim and 6° of right rudder, causing the aircraft to "crab" sideways across the sky.
