I just watched "Flight From Justice" again. I noticed they gave a description of McCoy of being between 25-30 years old. McCoy was 29. some people believe he was Cooper, however I see to many things different than the way it was done by Cooper.
1) He acted like a Co-Pilot (wind direction, speed, altitude)
2) Weapons vs Bomb
3) Wig was noticeable
4) 16,000 feet, and fly precisely at 200 mph
Since we don't seem to have any photo's of the stews getting off the plane, we don't have people with claims of trama.

Two flight bags loaded with cash and four parachutes were delivered to the plane. The hijacker, who had assumed command on touchdown, gave up his baggage check and had his luggage brought aboard. Fuel trucks hurriedly filled the plane’s tanks with thousands of gallons of jet fuel. After seeing the completion of his written directions, some three hours after the plane had parked, the gunman released the passengers and one of the stewardesses. He then ordered the rest of the crew into the cockpit and took a position in the rear of the aircraft. The hijacker then used the intercom to summon a stewardess. He gave her another set of flight instructions, telling the pilot to take off towards the east, climb to 16,000 feet, and fly precisely at 200 mph on a course that would overpass several specific Utah communities. The messages, now hand-printed, between hijacker and pilot were sent with increasing frequency, always using the stewardess as a courier. The cabin was ordered depressurized, and the gunman warned that if any pursuit planes were spotted he would detonate a hidden explosive device after he had jumped, before the plane could be landed.
The hijacker opened his luggage and covered the peephole between the cockpit and cabin. Observed by Second Officer Floyd Smith (fictitious name) through a slight space under the cockpit door, the hijacker quickly put on a jumpsuit, helmet, and parachute. Once he had shut off the cabin lights to better view the ground, the gunman demanded to be kept abreast of wind, ground, and air speeds; altimeter settings; and sky conditions.
After the aircraft passed over the last Utah community on his prescribed course, the hijacker sent no more notes. Hoping the incident was over, a stewardess ventured into the passenger area and determined that the gunman had indeed bailed out with the ransom into Utah’s darkened skies. Five hours after the hijacking began, the weary crew headed for nearby Salt Lake City International Airport. The FBI immediately searched the plane’s interior for evidence upon its landing. Any object the hijacker may have touched was examined. An array of material such as seat belts, gum wrappers, cigarette butts, and a copy of United’s passenger publication, “Mainliner Magazine,” was gathered by agents. One hand-printed note the hijacker neglected to take with him was also sent to the FBI Laboratory in Washington, D.C., for closer scrutiny.
Interviews with crew members and passengers traced the hijacker’s steps from the moment he boarded. One stewardess recalled the subject was flashily dressed. Other passengers and crew remembered a passenger agent had entered the plane after all had boarded at Denver to locate the owner of an envelope left in the waiting room. The subject claimed it, went into the lavatory for an extended period, and finally was told by a flight officer to return to his seat for takeoff. The general consensus was that the individual had donned a wig and moustache while in the lavatory. However, several passengers felt that more than one person was involved. The notes received by the crew generally used a terminology of “we this” or “we that,” thus giving this impression.
