57th Bomb Wing Emblem - WW II Theatre Made /447th Ennis/Connolly Collection

Beginning in 1940, almost 10,000 B-25s entered Army and Air Force service, and some 2,000 more went into British, Soviet, Brazilian and U.S. Marine Corps service.
Appropriately, one of the finest bombers ever to fly was named for Brig. General Billy Mitchell the dauntless advocate of air power.
The bomber first came to public attention in April 1942 when 16 modified B-25s were launched from the aircraft carrier Enterprise, flew nearly 700 miles to Japan, and attacked Tokyo and four other cities, their factories, shipyards, refineries and munitions factories.

One tough bird!
