The Cavanaugh Flight Museum’s P-51 Mustang known as The Brat III is a story of a true warbird survivor. Not only did The Brat III survive aerial combat during World War Two, it also survived foreign military service that lasted until 1984. Destiny moved in when The Cavanaugh Flight Museum learned about the original World War Two pilot, Hjalmar Johnsen, and decided to pursue a ground up restoration.
