- Date: June 30, 1951
- Aircraft: Douglas DC-6
- Location: Fort Collins Colorado, United States
- Fatalities: 50
- Phase of flight: En route
- Cause: Controlled flight into terrain. Investigators believed the pilot may have selected the wrong audio frequency switches in the darkened cockpit, so he heard the Denver VAR course identifier instead of the low frequency range signals.
United Air Lines Flight 610, a DC-6 bound for Chicago, crashed into Crystal Mountain about 18 miles west-southwest of Fort Collins while off course on the approach to Denver. All 50 people on board died.
