If the airline was to be closed down, then it would be a tacit admission that something had in fact happened, which is actually the opposite of what they are trying to achieve here!
At least something positive has come from this whole episode and that is FZ stopping the practice of having two sets of flight deck crew on their longer night turnarounds, which saw one pair flying out of Dubai and the other, flying the leg back. I suspect there are now some nightstops in the 'Stans' as a result!
