1941 Vultee BT-13A built by Consolidated-Vultee in California. It was a Basic Trainer (BT) in World War II. It was built in November of 1941 and was delivered to the Army Air Corp (there was not yet any Air Force) on December 2, 1941, five days before the Japanese attack on Pearl Harbor. The blue and yellow paint job shows that it was purchased on a pre-war contract since they stopped painting them in those colors after the war broke out. The nickname for the airplane is the "Vultee Vibrator" since the canopy really shakes when you spin the airplane. Any old WWII pilot will know what airplane you are talking about if you mention "Vibrator". The engine is a Pratt & Whitney R-985 of 450 horsepower. The 985 is cubic inches displacement which is about 16 liters.
