Ready to soar? The Cavanaugh Flight Museum offers rides in two distinctive warbirds, the N2S-4 Stearman and the AT-6 Texan. The N2S-4 Stearman is an open cockpit biplane used by all branches of the American armed services during World War II as a trainer. The AT-6 Texan was a powerful advance trainer with fighter-like features. It was the the final test of a World War II fighter pilot' readiness to climb into the cockpit of a Mustang, Corsair, Spitfire or other Allied fighter.
