A July 26 plane crash killed 3 members of The Nelons, 3 additional passengers and the pilot
A preliminary report revealed the final moments of the July 26 plane crash that left members of gospel group The Nelons dead.
The National Transportation Safety Board released the report on Aug. 28, nearly a month after the fatal crash took the lives of six plane passengers and the pilot. Three of the deceased were members of the Gospel Music Association Hall of Fame quartet.
The report revealed the pilot declared an emergency after the loss of autopilot and told the Salt Lake City Air Route Traffic Control Center controller he was trying to regain control of the aircraft. Witnesses also described the moments before and after the crash.
"One witness located near the accident site heard a ‘loud whining noise’ that diminished and then increased followed shortly thereafter by smoke emanating from the area of the accident site," the report read. "Another witness observed the airplane overhead in a ‘barrel roll’ maneuver and heard the airplane’s engine ‘roaring loud’ until they heard the airplane impact terrain. The witness stated that they saw the smoke in the area shortly after."

Prior to the single-engine Pilatus PC-12/47E turboprop airplane crashing, Dr. Alan Diehl, a former NTSB, FAA and U.S. Air Force Crash Investigator, Aviation Psychologist and author of, "Requiem for Camelot," described to Fox News Digital what the passengers on the fatal flight may have experienced.
"Dark terror. That's what you usually hear in my novel when I talk about [John F. Kennedy Jr.] falling from the sky," Diehl shared. "I said it was all over, but the screaming, and that's based on, you know, he didn't have a voice recorder on his airplane, but I'm sure that he and his two passengers were just in terror as the plane was falling out of the sky, much like this one."
"But of course, in this case, you know the actual breakup, we don't know — the plane may have lost pressurization. And in a way… if the breakup occurred early enough, and they lost pressurization, they may have actually been unconscious or semi-conscious at the last minute or so. And that would be merciful. They would say that was God's mercy."
