RANDOLPH AIR FORCE BASE, Texas -- TH-1H is the latest aircraft to join the Air Force inventory. It will serve as the undergraduate pilot training platform. Some major exterior differences from its predecessors are an enlarged nose, wider main rotor blades and the tail rotor is now on the starboard side for better performance. Inside it has undergone an extensive refurbishment including upgraded components and a new avionics suite with a glass cockpit. Current plans call for 24 of these former Army UH-1H helicopters to be upgraded. (U.S. Air Force photo by Master Sgt. Lance C. Cheung)
