“Grumpy” a B-25D Mitchell Bomber from the Historic Flight Foundation arrives at Ellsworth Air Force Base, S.D., April 20, 2012 as part of its return journey to Snohomish County Airport north of Seattle, Wash., from the final Doolittle Raider reunion event held at the National Museum of the U.S. Air Force in Ohio. “Grumpy” is one of the oldest flying B-25s in the world, and most closely resembles the variant of the 16 bombers flown by Lt. Col. James Doolittle and his crews during the famous Doolittle Raid. (U.S. Air force photo by Airman 1st class Zachary Hada/Released)c
