That video from Twitter will have to be reviewed in depth by the airlines regarding who sits at the over wing exits and how clearly and definitively they are briefed by the Cabin Crew that they are to only open it under instruction from the captain or cabin crew over the PA.
So often I see wholly unsuitable passengers (for example, foreign passengers not from the airlines' country, 5 foot nothing women that don't know how heavy 33lbs is, passengers sleeping as soon as they get on etc.) sitting by the over wing exits.
Referencing the Twitter video with the oh my god screamy guy from page 1, it was a good minute from the left over wing exits opening to him escaping through door 1L when the number 1 was spooling down. That is so dangerous.
Such a long time to have passengers on a wing and behind an idling engine with the exhaust blast and heat etc.
As the co-pilot was asking Tower if they saw anything, the slide was being blown.
To our US pilots/AA pilots, in AA, is there an early PA to passengers (within 5 seconds, say, of stopping) saying something like, 'Everything is fine, we're dealing with it, give us a sec', or is their SOP to deal with everything first in cockpit, talk to cabin crew, tower, etc and then deal with the passengers?
