This question already has an answer here:
What is the procedure for aircraft, if the ATC they were relying on to land, is, in some way, completely disabled? (for example there is a fire that destroys the whole building and all equipment).
If this happens at a busy airport, do the aircraft simply communicate with each other to organise who will land first etc.?
For the purpose of the question, assume there is no other tower within range that could reasonably pick up the job and that there are aircraft that must land there (they might have already been in holding for 2 hours plus and have no fuel left).
This is not a duplicate as I am specifically asking about cases where they have not been diverted to another airport, are in holding, run out of fuel and then ATC tower gets disabled.
