Airmen from Ellsworth Air Force Base and citizens from Rapid City, S.D., turn out to greet the Historic Flight Foundation’s B-25D Mitchell Bomber named “Grumpy” alongside of a B-1B Bomber in conjunction with the 70th Anniversary of the Doolittle Raid at Ellsworth Air Force Base, S.D., April 20, 2012. The base’s three current flying squadrons – the 34th Bomb Squadron “Thunderbirds”, 37th Bomb Squadron “Tigers”, and the 432nd Attack Squadron – each have a historic tie to the famous Doolittle Raid.
