Lancaster Bomber
The British Avro Lancaster was one of the most successful heavy bombers of War War II. More than 7,300 were built. It flew 156,318 bombing missions, and dropped a total of 618,000 tons of bombs. It could carry a heavier bomb, and at a higher altitude, than any similar aircraft and was very maneuverable for its large size. Flying a Lancaster was a physically demanding job. The crew flew to an altitude of 21,982 ft. (6,700m) for up to 12 hours. They had to breather oxygen through a face mask often in temperatures as low as 23 degrees F (-5 C). The Lancasters rarely had fighter escorts, and flew mostly at night to avoid being attacked.
