So British airspace is open for flights again. But the actual situation of the ash hasn't changed. Neither has the evidence regarding how safe ash is to fly through.
But presumably this means it is safe to fly through the ash, which begs the question WHY did it take so long to be certain? Our tardiness has been costly. Or it begs the question: if there is no new information, can we really be certain that ash poses no threat?
There is an inevitable cock-up here. If the ash is safe, then the problem was not knowing that and unnecessarily prolonging the flight ban. If the ash is dangerous, the mistake is declaring it safe...
Time will tell which is the case.
