that this event was in the tail section behind the bulk head (prob wrong on this)
The ELT is located FORWARD of the rear pressure bulkhead. That is why they were able to tackle the fire from the rear cabin.
If this had been in flight then most likely the flight crew would get down quickly enough to avoid explosive decompression once the fire burned through to the outside. From that point on, aggressive use of the rudder and elevator would need to be avoided as the tail section would more than likely distort as a result of fire/heat damage rather than just fall off as happened with JAL 123.
