Very bored Two's in - well until Saturday when my local re-opens.
As for a spiral. There is the nub of my question, why conform to normal operations? Why not just call London and have them watch a continuous climb on a direct track, given that there is next to nothing in the airway?
The various corridors are the way to go in normal times, but perhaps a bit of thought outside the box given the amount of traffic over the last few months.
Perhaps the real answer for me is less internet and back to Classic FM and Private Eye!
