N to S transit to the east
I am not sure if I am reading the map correctly but there seems to be a piece of clean Class A (FL055+) in the middle of D138, so it looks just possible to squeeze past, along the edge of the RA. You will clip a tiny piece of D136...
There is going to be an awful lot of traffic trying to squeeze through there, at various heights up to 4300ft.
I can't see why the RA extends so far to the east. Are they using Southend to ferry a load of people?
I feel sorry for the schools in the area.
Bin Laden must be jolly pleased, to have the decadent west running around in circles like this. Thie must be the best value for money operation he has ever done.
