Alex was not well rested, had only a few hours of sleep.
He had winter closing on him, which made reaching PC more difficult. He already had problems with reaching his PC in that jacket before once, but got lucky that time.

Perfect weather conditions, solid exit. He made 4 attempts to find his PC, hit the ground during the fifth in stable box position, no panic. His PC was found half a meter next to him on the ground, probably thrown out from impact.

Lessons: Rest up, go hand held below 100 meters, especially if you have difficulty reaching your PC. And if you must go stowed, don't stow it all the way, leave some to grab it more easily.
