The Personal Courage wing is a new two-floor exhibit dedicated to aviation during the first two world wars. The museum of flight was able to exhibit the collection of the Champlin Fighter Aircraft Museum on the condition that the provide a dedicated space for the aircraft, and it's fair to say that they've done that.
In fact, I think this is one of the best museum displays that I've ever seen. The sound, lighting, and staging are all world class. From the world's first fighter plane that greets you as you enter the WWI section, the 1914 Caproni Ca 20, to the 400 MPH P-38L Lightning of WWII, everything is beautifully done.
