That sounds plausible. I do suspect the warning caused him to react but either way with flying blind it was likely he would of hit a mountain side. Something was wrong because more than one person said something was wrong with the sound as described as sputtering drawing attention it and one saw it going down then heard a crunch. Another said heard a loud bam or something.
I’m guessing Koby wanted to get there for a game with the girls and didn’t heed warnings if they were warned. In poor weather like that the path they took should of been checked first. Even way north of it, it was really foggy that day.
I know a helicopter crew chief who moved a bit away now who was in both Nam and Germany. The officers knew how quickly things can go wrong in copters so why he was in Germany he got drinking privileges as long as he was sober when they needed to get somewhere.
The pilot you mentioned was right. Celebrity’s have died by taking chances under pressure to get somewhere.
I started to learn to fly Cessna’s at 18 but that’s another story. It was fun.
