The captain of a KLM DC8 overheard the incident on radio. He held his aircraft at Kemayoran (as was) and went to the Indonesian immigration authorities to demand that he could casevac to Singapore.
Dude, Kemayoran closed like 30 years ago.
And back then, you didn't need your passport to deal with Indonesian immigration. A fiver would've sufficed.
Anyway, in emergencies, passengers are going to do what passengers are going to do. If you design procedures based on perfectly behaved passengers, well, prepare to be surprised.
There have been lots of cabin design and procedure changes over the years because of new insight about how passengers actually react in real life situations. Pushing, shoving, blocking exits, grabbing bags, inflating life vests inside the cabin, ignoring commands, fighting with flight attendants, fighting with each other, etc., etc.
