I think it would help if people knew why 90 seconds is the goal: because the real danger in a plane crash isn't the crash, it's the post-crash fire. I'm speaking generally of course. For something like Sioux City for example (total loss of hydraulics/controls), the crash is obviously catastrophic. But even in that case, the post-crash fire added to the death toll significantly.

I don't think passengers realize this. No sane airline would ever mention it in a passenger briefing. Can you imagine? "P.S. If we crash, get off right away or you'll be burned alive." Never gonna happen. But it's the truth, and it's why getting the f* off the plane as fast as humanly possible after a crash will save your life—and the lives of all the people who can't get off until you do because they're stuck behind you.

That's the other thing I don't think people realize. Grabbing your bag may take you two seconds, big whoop. But what if two seconds is the difference between life and death for the person thirty people behind you in line out the door? You just killed that person.
