Having been very closely affiliated with the UK Concorde program, I can categorically deny and scotch any rumours that the once graceful lines of Concorde will ever grace our skies again. Most spares (if not all by now) have been sold for scrap as they were unique to Concorde. Some engines were sold to various museums to be put on display, various other parts donated as well. Specailist tooling jigs and equipment no longer exist.
I for one in the beginning of the demise, dreamt of one ship being kept airworthy, but alas the costs would not be financially viable for either airline to carry. No amount of public outcry and petitions will see the boards of any CAA/DCA convene to discuss even a single flight. The C0fA was withdrawn permenantly, pilots re-assigned and type ratings expired. Engineers placed on new courses now dedicated to other types in the fleet.
I dream too, but it is only a dream. The reality is now of M0.82 and FL370, slow sedate climb rates reaching 250knts after 10 mins instead of at the end of the runway, oceanic clearances done at a lesurely pace, regular excursions into the lovely holding patterns instead of bounding through at 280knts for a straight in. No worries about SSC tracks and wondering if you have slowed down 20 miles too late. Ah those were the days.
