World War II, aficionados, history buffs and just plain ol’ lovers of aircraft of any kind made their way into McKinney over the Oct. 5 weekend for the Commemorative Air Force’s (CAF) Air Power Expo, a collection of World War II vintage military aircraft. The event was held at the Collin County Regional Airport and featured a collection of aircraft rarely seen in the 68 years since the end of the war to end all wars. The CAF brought out military transport planes, fighters and bombers. Walking into the gates a P-40 with the iconic Flying Tigers mouth on the front greeted visitors, while a B-24 Liberator bomber (dubbed Diamond Lil) sat waiting for walk-throughs of its bomb bay area. Visitors could even lay hands on machine guns inside the aircraft. The star of the show was FiFi, the world’s only remaining B-29 that actually takes to the skies.
