Judging from Suggs's post the mods to Concorde are more substantial than we have been led to believe, with the ability now to get to at least 119,000 feet. However, that is as nothing compared to what you must have been flying down from Aberdeen, Suggs! The rate of descent into LHR from Midhurst at 120,000 must have been awesome to behold....
But seriously, it must have been a great sight and if I had been one of your pax I would have been there at the window too.
