BA 38 went down in Heathrow coming from China. No one was killed and the plane did not burst into fire. However, people left by slides - some were injured.

An AF 340 from France went town in Toronto some time ago. No one was killed, either, but the plane did burst into fire and burned into a wreck.

Some AF passengers were critizised for taking hand luggage along on evacuation. Passengers are supposed not to do so when leaving by slide (as opposed to leaving by airstairs, like the SQ A380 stuck in mud).

What is the immigration status of passengers who arrive from aboard with no visas or identity documents because those burned with hand luggage in evacuated wreck?

What is the immigration status of passengers whose documents exist, but are in the evacuated and empty plane wreck?
