The Dornier 17 was one of the medium bombers that the Luftwaffe used during the Second World War but only for a short period of time. The max range for the Dornier was 721 miles and it flew at a top speed of 255 Mph. It was pulled from service after 1941 due to lack of defensive weapons and being vulnerable to attacks at the underbelly and rear of the plane. The following History Channel video gives a good idea of WWII Air Power:
The Boeing B29 Super Fortress was a heavy bomber for the United States. It was powered by 4 2,200-horsepower engines and it could either carry 16 500-lb bombs or one 2,000-lb bomb. When empty, the Super Fortress could fly at 400 mph and as high as 30,000 feet. An earlier version of the Super Fortress has a defensive armament of 10 50-caliber machine guns and each a belt of 1,000 rounds while later versions carried 20-mm cannons instead of 50-caliber machine guns. The most famous Super fortress was the Enola Gay which dropped the first atomic bomb.
