The USAF Museum aircraft is an F-106A Delta Dart. It had a problem somewhere out there (North Dakota IIRC) and the pilot ejected safely. Without the pilot and seat it stabilized nose-high and pancaked gently into a snow-covered field.
When the recovery crew arrived the engine was still running. As the heat from the engine melted the snow, the jet would lurch forward across the field until it hit fresh snow, which would stop it. When that snow melted... Finally, a brave (foolhardy?) guy jumped on the wing, straddled the fuselage and crawled forward to the cockpit to shut off the J75. The aircraft was repaired.
