May I just point out
again that Lndon FIR, fine fellows that they are HAVE NO RADAR and if you do have to ditch they will know you are going to get wet, and that's about it. Bournemouth, Southampton, Manston Wattisham, Norwich, Anglia Radar are all radar units who will be able to plot your position down to the point you go below cover & can vector other units on to you. Cover from Manston, Wattisham, Anglia & Norwich overlaps with Continental radar cover so you can be tracked all the way
