Can,t answer your question but showing on FR24 right now(16:12 16/02/13) is BAW49 currently doing a series of turns out on the coast near Clacton.
I first noticed it circling over Milton Keynes and Northampton @FL90.
It then headed south then east which at that point i thought it was heading back to LHR.Obviously not going to SEA any time soon.
Anybody know anything?
