I wasted an inordinate amount of time analysing the whole thing myself, including but not limited to finding the location based on geographic features - and then testing in Flight Simulator.
I'm pretty sure I wasn't the only one.
I'm disappointed he's not thrown in jail for reckless endangerment.
There was for a time a micro-industry of people taking flights to this location on Youtube -- it's one of the most fun examples of this that I've seen.
And yeah; really quickly people discovered that he genuinely had options.
There is a question I've not seen answered yet. Did the wallet guys know he was doing this in advance?
He also removed the ending, and both the beginning and ending were the pretext for the flight – bringing his friends ashes in a used sandwich bag to be scattered in the mountains, so could have instead been removed to reduce the cheese factor.
…suffice to say lots of people have gone through his video frame by frame to find weird stuff.
