Nothing is impossible thus I agree.
Does either of those islands have a landing strip long enough to handle a 777?
Anyone remember the pro golfer who died in a plane that had anesthetized/killed everyone on board?
That plane flew a long time without any live humans. Much smaller than this 777, but it could still be a massive accident.
I also saw something along those lines on Air Disasters or such. Don’t recall the flight, etc, but think it was Asia. Might have been a fire in the hold that put fumes up in the passenger compartment and caused many to pass out.
