Journalism Wanted: if you evacuate a plane and leave your belongings behind, what happens next?

If you're on a plane that crashes and you have to evacuate, you're supposed to leave your belongings behind. And every time there is a plane crash that makes the news, you hear about people trying to bring their belongings with them.

 

An easy way to prevent this would be to widely publicize what actually, in real life, happens to people who evacuate a plane and find themselves on the tarmac of a strange airport in a strange country with only the clothes on their back. (Which might not even include coat and shoes, because sometimes people make themselves comfortable on airplanes.)

 

What measures are in place to keep people safe? How do they avoid the pitfalls we can all anticipate, and those we can't?

 

Suppose your passport is on the plane. You're in a foreign country with no passport and no ID. Maybe it isn't your destination country and you aren't actually legally permitted to enter that country. What measures are in place to regularize your presence so you don't get arrested and imprisoned? What if the country you're in isn't safe for people of your demographic?

 

Suppose your wallet is on the plane. You have no money and no cards. How do you get all the things you need, including random incidentals like menstrual pads and eczema cream?

 

Suppose you lose your driver's licence in the plane crash and need to drive home from the airport. What provisions are in place to keep the cops from arresting you for driving without a licence?

 

What if your baby's car seat is in the plane? How do you safely and legally get, like, anywhere? 

 

To what extent are they assuming goodwill ("Don't be silly, the authorities won't arrest you for being in a foreign country without a passport if you've just been in a plane crash!") vs. having actual procedures in place ("This is your official internationally recognized Plane Crash Survivor card")?

If they actually want people to leave their belongings behind, they need to let people know what measures are in place to protect them. But I've never seen anyone report on this - it's always just "These plane crash survivors are Bad and Wrong for trying to collect their belongings!"
