It is really impressive that the entire plane was evacuated from two exits in less than 90 seconds. The flight crew followed a defined process and the passengers followed instructions. Training and Discipline. I have always marveled at the Japanese capacity to order their society. That is the fruit of this tree.
I’ve only been one other place/plane type where it was regularly loaded and unloaded with passengers in such a short time. It was ‘that other airline’ out of LV......
The Key is keeping passengers from crowding the aisle(s) until their row is next to leave. Same thing on reverse for loading. Back to front - no picking seats.
But this was with people who knew the ‘routine’ and flew like that daily. For an amorphous group like this in Japan says quite a lot about the people and ability to follow instructions.
The costs of a compliant society are creativity and imagination.
Yes, that is very impressive! It’s sad that the Coast Guard crew died, but wonderful that all of those other people survived.
