Greetings, Next photo from your tour; Another aircraft not on show this time its being restored according to the website. I could see the main restoration hangers from the museum. As with most pilots in the RFC, U.S pilots also mainly trained on these in England before going into inferno that was WW1. The U.S. Army Air Service eventually established its main training center at Issoudun, France, and in July 1918, the American Expeditionary Force (AEF) commanders ordered 52 Avro 504K aircraft for teaching aerobatics at Issoudun. After the war, the Army Air Service brought a few Avro 504K aircraft back to the United States, and they remained in training service for a few years. Using original parts, the Royal Canadian Air Force's Aircraft Maintenance & Development Unit built the aircraft on display in 1966-1967 with a 110-hp Le Rhone J rotary engine. It arrived at the National Museum of the U.S. Air Force in May 2003, and it is painted to represent one of the 52 Avro 504K aerobatic trainers used at the AEF No. 3 Instruction Center, Issoudun, France, in 1918. Shot from tour with Bill, not this time, next photo is though. Rob
