Many moons ago we heard that the B of B flight was going to do a flypast down Runway 28r [Tells how long ago it was] so many hard bitten "Techies" whose office and crewroom were at the end of the "bravo" stands in the central area decided to witness this event ,,prior to this normal takeoff were carried out and not a blind bit of notice was made as the cream of the major airlines took off including Concorde but about 5 mins was allocated to the flypast down the runway and normal traffic was halted and a lengthy line aircraft was waiting and we all went AHHH!!!as they trundled past .
don't think it will happen now
