It's easy to identify the Y shaped delta of the mountain ridges just 2 clicks north of the Manzana School Camp, with the plane travelling westwards. 34.8081872, -119.9438522.
Given the near service ceiling altitude the dude had plenty of opportunity to double back to eg 34.7683290, -120.1101663 . Not exactly sure how much gliding range it has, but can go to just over 60km/h before stalling, and can't be radically different from a Cessna which will do "1.5 nautical miles per 1,000 feet of altitude above ground level". The landing gear appears made for grass fields.
Of course, one might speculate, given lack of in-plane footage and everything else, he could also not have throttled the airplane and landed it normally instead of pulling this pathetic stunt. Ie it appears reasonable to assume that the entire thing is a complete fabrication.
Who carries a hip altimeter (a few frames of 4:03) and full parachute when flying, as well as covering every angle of the "emergency departure" with GoPros, not a single frame of the "emergency" instruments despite another GoPro in full view, freefalls for ages instead of taking their time to assess etc, then avoids several flat spots including flat riverbeds that were a great alternative to doubling back if completely panicking on basic arithmetics, only to land in dangerous bushes instead "for the views". And then complains of being so so thirsty whilst carrying the whole chute around in his "life and death" situation.
Look at the YouTube history, the guy's pathological prankster.
Lots of camping sites and such in the area, just look at the coords in your favourite map provider. It was reckless beyond belief.
Should I not be wrong with my analysis (having spent a few hours reviewing this), I hope he goes to prison for a very long time.
