On 21 April 1945 B-24 Liberator "Black Cat" (42-95592) of the 784th Bomber Squadron, 466th Bomber Group, 8th Air Force, and is considered the last heavy bomber to be shot down over Germany in WW2.

On 21 April 1945, B-24 bombers from the 8th US Air Force to include the 466th Bombardment Group departed from their air force bases in Norfolk, England to bomb a railway bridge in Salzburg, Austria. Within the formation, "Black Cat" led the third squadron. However once the target was reached four hours later, the mission had to be abandoned due to the heavy cloud and thunderstorms covering the area. The lead aircraft flew a return course over Regensburg. At 20,000 feet above Regensburg, the formation received eight bursts of flak. Black Cat was the only casualty. It was struck by a shell on the left wing causing the aircraft to crash. Ten of the crew were killed including the pilot, Richard Farrington.

1LT Richard J Farrington, O-713376, MO, Pilot
