I started to visit the Commemorative Air Force museum down in Mesa, Arizona back in the mid 90's and one morning I walked inside and parked in their hanger was a Heinkel He-111. It was sitting back in a corner and nobody was around yet, so I climbed inside thru the side hatch. Mounted just inside the door was a MP-40...hmmm to fight off stowaways?.. I thought. I probably spent the best 20 minutes by myself inside that bomber and grabbed the dorsal mounted MG-131 and took several pictures. This CAF's aircraft was a Spanish built version of the He 111 and was officially designated a CASA 2111 and was purchased in England in 1977. But on July 10th 2003, it was involved in a crash landing that ended fatally. This tragedy of a landing happened while attempting to land at Cheyenne Municipal Airport after flying from Midland, Texas. It was en-route to an air show in Missoula, Montana when the accident occurred. Eyewitness accounts state the aircraft appeared to lose power in one engine while on its final approach to the airstrip and crashed through a chain fence. Following this, it then collided with a building (a school bus-washing business) that was undergoing construction. Sadly in this collision, the pilot, Neil R. Stamp and co-pilot, Charles S. Bates, were both killed in the crash and the aircraft was a total loss. I talked to the Mesa museum later on about the crash and one employee said it was due to pilot error..not sure what the final FAA report said what caused the crash.
