The propellers that were used on the bombing mission were later shipped to Texas A&M University. One of these propellers was trimmed to 12½ ft for use in the university's Oran W. Nicks Low Speed Wind Tunnel. The lightweight aluminum variable pitch propeller is powered by a 1,250 kVA electric motor providing a wind speed up to 200 mph.[17]
