The pilot subsequently reported he took off with 14 gallons of fuel aboard. The flight from Bull Frog Basin Airport, Utah, to Winslow, Ariz., should have taken 1 hour 40 minutes, with fuel consumption of 5.3 gallons per hour. The pilot noticed that fuel was disappearing quickly and assumed there was a headwind. After 1 hour 40 minutes (1.7 hours), the airplane ran out of fuel 57 statute miles north of Winslow, and landed in the desert.
