Previous claim they were 20-30 feet from missing the hill is true, BUT they would have faced the next hill almost immediately. Based on description of final descent in altitude from 2,300 to 1,300 the pilot was likely disoriented during that span and might not have know if he was climbing or falling. Imagine finding yourself careening in a pool of milk and not knowing if you were up or down. Rather than looking at gauges, he was probably in a panic searching for something visual to orient himself by. That was probably what was going on for those last few seconds. But even if he had been 30 feet higher, at 165 mph plus he was a few seconds away from the inevitabile given that terrain.
Seems the lessons coming from this will be when and when not to give pilots (especially those whose crafts or themselves are not permitted) special visual flight rules. Also, from a pilot friend, it’s never a good practice to have a single pilot on a craft, if you can help it.
