Named after the controversial champion of U.S. Airpower, General “Billy” Mitchell, the B-25 is best known for the April 18, 1942 bombing of Tokyo. Led by Lt. Col. Jimmy Doolittle, and flown from the deck of the aircraft carrier USS Hornet, 16 B-25s successfully completed the first strike on Japanese soil during World War II.

The Lyon Air Museum B-25 Mitchell, “Guardian of Freedom,” flew combat patrol missions in Alaska and around the Aleutian Islands during World War II before coming home to be used as a trainer for our country’s next generation of pilots and crew members.
