And...the only chance of keeping at least 1 Concorde flying for
special occasions will be if they do retire one at Filton where
they've got the people and facilities there to service her.

Does anyone know if BA have officially announced the retirement plans
yet?

http://www.concordesst.com/retire/diary.html seems to have a comprehensive
'diary' of events. It appears from there that the 'last ever' flight will
be G-BOAF from Heathrow to Filton on Nov 17th although the 'real' retirement
will be on October 24th when 3 Concordes land at LHR at 90 second intervals.
