B-24 Liberator Bomber

The B-24 Liberator bomber was a four-engine heavy bomber used throughout the world during WWII. There were few campaigns anywhere that did not use this rugged beauty. My wife's uncle was a gunner on one of these, serving in Africa, Italy and finally over Germany, where his plane was damaged on a bombing mission. The plane lost engine power and was unable to gain altitude enough to  return over the Alps mountain range. He bailed out on the German side and was captured. He spent one year in a German POW camp.
These planes were used as bombers as recon and as ground support in the Pacific Island chains. There were 18,400 of these produced during WWII and that total remains today as the most U.S. aircraft model ever built.
