The DC-9 crashed in a wooded canyon with approximately 60° slopes He parachuted to the ground without injury. The F-4 began to tumble violently about the lateral axis and the RIO ejected from the aircraft. The Phantom struck the forward fuselage of the DC-9, causing the nose section of the DC-9 the separate from the fuselage. The pilot initiated an evasive roll but a collision could not be avoided.

Due to deteriorating visibility, they again climbed to 15500 feet northwest of Palmdale. After crossing the mountains, they descended to 5500 feet and later further down to 1000 feet. The flight departed at 17:16, climbed initially to 7500 feet, and then climbed to 15500 feet to clear mountains and some clouds. The maintenance personnel on duty at NAAS Fallon were unable to provide the appropriate repairs, so it was decided that the Phantom should continue to MCAS El Toro at low altitude. The crew of 151458 then flew to Naval Auxiliary Air Station (NAAS) Fallon, Nevada, for further repairs. No attempt was made to restore the radar to peak performance at that time. They confirmed the oxygen leak, but could not repair it. ![]() Maintenance personnel replaced a fuse to fix the radio, but they did not have the personnel to check the transponder. Meanwhile the flight leader continued back to MCAS El Toro. The radar and transponder were inoperative, there as an oxygen system leak and the radar system were degraded. During a refueling stop at Mountain Home AFB, Idaho, on the way back, 151458 was grounded for repairs to have mechanical difficulties checked out. Marine Corps F-4B Phantom, 151458, was part of a two-ship formation that had departed the Marine Corps Air Station (MCAS) El Toro, California on Jon an overnight cross-country return flight to McChord Air Force Base (AFB), Washington. ![]() zero four zero direct to Daggett." This was the last recorded transmission from the flight. The flight reported leaving 12,000 feet at 18:09, and the controller advised, "Air West seven zero six red, turn left heading zero four zero until receiving Daggett proceed direct." RW706 acknowledged, "OK. The flight departed Los Angeles International Airport at 18:02 local time and following radar vectors from Los Angeles Departure Control, contacted the Los Angeles Air Route Traffic Control Center (ARTCC) at 18:06. Hughes Airwest Flight 706 was a regularly scheduled flight from Los Angeles, California, to Seattle, Washington, with intermediate stops at Salt Lake City, Utah, Boise and Lewiston, Idaho, and Pasco and Yakima, Washington.
