I found a link for this trail a while ago so we did this trail (and 3 others today). This thing crashed when I was 1! I found it interesting that so much was still there.
Two people were killed in the crash that happened on Jule 27th, 1965. It was a T-33A jet trainer, and the pilot was a very experienced Air Force Major named Jay Currie. First Lieutenant Donald Darby was riding along as a technical observer. They were flying from Buckley Field to California, and Major Currie was viewing some property he owned in Colorado, flying at 13,000 feet.
The reasons for the crash are not known. He was told to go to 17,000 feet by Air Traffic Control, but then contact was lost. It is known that he was flying slowly, there were no technical issues with the plane, and neither of the pilots attempted to eject from the plane. There were thunderstorms reported in the area, which may have contributed to the crash.
