>and it didn't look like anyone was in serious danger after they realised they'd survived
There was fuel gushing from the severed wing, hence why the water spray just above one of the exit doors, and you could see fire trying to flare up. It had the potential to turn catastrophic...or more catastrophic...in an instant.
There was a lot of behaviour that isn't super ideal, for instance people milling right near the plane seemingly to take videos/photos not only restricting the emergency crews but in a danger area.
I get people in shock from a near death experience doing irrational things like that, though. More concerning are the number of people rationalizing it with full clarity and consideration. Like on Reddit the number of people talking about how there is no way they were leaving their carry-on because their laptop has important work, or their bottle of aspirin, etc...just disastrous logic that literally gets people killed. Standing right in the area where emergency crews are trying to stop a plane from erupting into a fireball for that once in a lifetime selfie -- absolutely crazy behaviour.
It's not unusual for people in a plane crash to survive, then die from smoke inhalation because the people in front of them took too long to evacuate the plane.
Per the referenced link, of the 35 serious incidents between 1983 and 2017, there were 3,823 aircraft occupants. In that group, if you either survived or died from smoke/fire, there is a 7.2% chance you died from smoke/fire.
I can't fine tune that number to determine you survived the crash, but then died from smoke or fire, since it did not easily differentiate pre-crash and post-crash fires.
I am not sure I would agree or disagree that it is usual to die from smoke inhalation after surviving a plane crash given the reason that people took too long to evacuate. It just feels like the upper limit of how many people die that way can't be that large since many of those smoke/fire deaths would not be attributable to that cause.
It's literally once in a lifetime, and it didn't look like anyone was in serious danger after they realised they'd survived.
