BOAC - I know. I understand why it's dragged out, just not so sure about the circumstances leading up to the need to do so. I'm probably missing something fundamental about how the whole process works.
What I was driving at is that if you're going to give a late clearance, I would have thought it would need to be quick. I do see the point about keeping control of the frequency, however.
Anyway, happy to leave it there.
