How do you know what their 'arousal level' was? I can see two people in the back on dispatcher harnesses who are sitting in their respective doorways
There is your first clue - sitting there, feet dangling, no head movement for clearances, no looking under or above (lookout).
The second clue is the lazy left turn, which is what puts the aircraft closer to the edge before the coup de grace of the hard right turn that does the damage.
Are you saying a crew with a high level of arousal wouldn't have appreciated the proximity of the tailwheel to the edge
before the right turn or that there was an
obvious right turn coming in order to get to the parking spot?
No, I don't have super-intution or a mega PC, but after 35 years in multi-crew military helicopters, I have a pretty good idea how things are supposed to go - and that ain't it.
