Avro Lancaster

Lancaster, also known as "Lanc" - the most used British heavy bomber of WWII. Lancasters flew 156,000 missions. The Lancaster was a development of the unsatisfactory twin-engine Manchester. It had a rectangular fuselage, mid-set wing and twin tail fins and rudders. It was able to carry very heavy bombs and bulky 'special' weapons; with modifications to the bomb-bay even 10.000kg bombs were carried.
Lancaster has a Martin upper turret with two 50-calibre guns. Maritime patrol versions had no top turret, and only the front turret was armed with two .303-calibre machine guns. Drafty, noisy, and uncomfortable on long flights, the Lancaster was nevertheless strong, reliable, and a delight to fly.
