Narrative:
The Curtiss Commando departed Chicago for a flight to Denver. An refueling stop was made at Omaha from where it departed at 01:39 on a contact flight plan to Denver at 8,000 feet. At 04:14, the crew reported over the Watkins Fan Marker, 14 miles east of the Stapleton Airport, and requested permission to make a practice approach on the ILS, which was approved. The C-46 contacted the ground and crashed on the up-slope of a slight hill 218 feet past the middle marker antenna pole of the ILS and 3232 feet from the end of runway 21.

PROBABLE CAUSE: "The Board determines that the probable cause of this accident was the momentary loss of control or overcontrol by the pilot at a critically low altitude in the final stages of an ILS approach. A contributing factor was the failure of the safety pilot to remain alert to the altitude of the aircraft."
