Having worked with many clients in a post-operative setting, I know that rehabilitation and recovery is different for everyone; however, good nutrition after surgery can speed wound healing, improve immunity and ensure the best outcome.
The Boeing B-17 is by far the most famous bomber of World War II. In 1934 the Boeing Aircraft Company of Seattle Washington began construction of a four engine heavy bomber. Known as the Model -299, first flight was achieved on July 28th 1935.
US forces managed to get a few fighters off the ground and used them, but not any other kinds. In the rest of the war EVERYBODY used fighters, bombers (regular bombers as well as dive bombers), reconnaissance planes, and torpedo planes. The Japanese used the Zero fighter, the Val and the Kate at Pearl Harbour, as I recall.
