Commemorative Air Force
The Commemorative Air Force (formerly Confederate Air Force) is a major preservation and education organisation based in Dallas, Texas. It started in 1957 with the purchase of a P-51 Mustang and has grown to the point here it now has 13,00 members and more than 175 aircraft of 60 types, many of which are hosted in CAF Regional Wings.
They hold an annual airshow that can only be described as spectacular! It should be on every aviation history buff's wish-list.
