The Tough Texan is a single engine advanced trainer used to train fighter pilots of the United States Army Air Forces, United States Navy, Royal Air Force, and other air forces of the British Commonwealth during World War II. Manufactured by North American Aviation, she first flew on the 1st April 1935 and there were 15,495 built. The Texan was developed from the North American BC-1, the CAC Wirraway and the North American A-27. Four Hundred of the type were delivered to the RAF, and known as the 'Harvard I' and after a change to the rear canopy it was designated the 'Harvard II' for RAF, and RCAF orders. She had many upgrades one being the fitting of the Pratt and Whitney R-1340-49 Wasp radial engine, then becoming the 'Harvard III', AD-6D the RAF receiving 351 of this airframe. In 1937 the Mitsubushi Aero Company, of whom I did not know existed then, purchased two NA-16s as technology demonstrators and possibly a license to build more. Max speed at 5,000 feet 208mph,[335 km/h at 1,500m. Cruise speed 145mph [233 km/h]. Service ceiling 24,200 feet [7,400m]. Range 730 miles[1,175 km]. Provision for up Twp 3 0.30in [7.62 mm] machine gun. A Friend of mine owned a Texan and one early morning drove the aircraft into the hanger doors, the doors were badly damaged but, after the strip down of the wings the only damage was to the leading edge and not to the frame, I should add that the doors were open.... but not fare enough, it was like watching that film, 'Those Magnificent Men in their Flying Machines' ! I heard words that I have never heard since.!
