>The plane isn't even full of smoke yet
The plane previously had some pretty impressive flames in the process of landing, and depending one what sort of fire gets going there might not be time for everyone to get out. That being said, insulin isn't actually a valid excuse nor are very important legal documents. Every second counts, and could be the difference between life and death for passengers and crew not yet evacuated. There's a reason that air traffic controllers ask pilots in emergencies for the number of "souls on board" referring to living humans and not important legal documents or medicine.
