I posted the following on the FC Forum a little while ago.
As I say , make of it what you will , but it certainly suggests the Bears
flew as far east as Eastbourne before turning about.
A replay of yesterday's movements in the Channel show the Typhoon heading east mid channel on the edge of UK FIR
It then turns about abeam Eastbourne and runs parallel to the FIR boundary with tanker some way behind until abeam Selsey
where the Typhoon carries out one RH orbit and meets the tanker and starts refuelling.
Tanking is complete abeam Swanage , tanker turns north , Typhoon departs to the west again following the line of the FIR boundary.
Make of this what you will , but it suggests that the Tu54s "did" fly up channel as far as a line Eastbourne/Dieppe
