If indeed this was not staged it seems to me incredible - that is, beyond the bounds of credibility that;
One would transit hills at such an enormously unnecessary altitude
Pump the yoke in that extraordinary manner that has no purpose known to an aviator (but maybe looks impressive on youtube)
Wear a skydiver's parachute
Not attempt to restart the engine
Not attempt to glide clear (from said enormous altitude)
Not attempt a forced landing in the many washes and meadows available
Have the "presence of mind" to bale out and play with a selfie-stick but not take water.
Freefall for so long
Not parachute from great altitude to a safe low-level landing area
Deliberately parachute into an inaccessible poison-oak infested mountainside crash-site instead of the above, with the addded risk of arriving at a bush-fire from the crashed aorcraft.
A truly staggering performance!
