Some interesting behaviors demonstrated here when the crew were far away from supervisory members or any obvious regulatory constraints. Flying safely when on Operations is instinctive because you train for it, this crew appear to have been seduced by the apparent lack of oversight and the opportunity to do some sightseeing. The lack of judgement started well before the hypoxia kicked in. Not saying that they behaved this way because they were civilians in an OA, just that Military types are more aware that when no-one is watching you, the risk levels are higher. Curious that this appears the same day as "Pablo" decides that he can be selective with burdensome rules, similar behavior, just different ends of the spectrum.
