Art Grube, a veteran of the Army Air Corp during World War II who served as pilot or co-pilot on 35 missions over Europe, flew on the Aluminum Overcast, a World War II Boeing B-17 bomber Thursday, Aug. 29, 2013. In the service, Grube flew the B-24 and said this was his first time on the B-17, but there were plenty of similarities. "I thought it was a very good," he said of the flight.
