I went to have a poke around G-BOAD this afternoon at the Intrepid museum.
Am sad to say she's in a bit of a sorry state - paint peeling off in places which is no doubt due to being outside in the full weather of NYC. For example, there's still several inches of snow on the wings/elevons from the storm half a week ago.
Inside is no better - visible mould on some of the seats which are enclosed underneath a plastic display case type affair, printed on which are some alleged facts about Concorde, but at least one of them was completely wrong.
Such a shame. I have only been to see two of the preserved frames, this one and G-BOAA at East Fortune and I have to say the latter is a far better experience. At least someone seems to care about educating people about the aircraft and keeping it in good 'nic, which is not what you can say about the one in New York.
