Even with my life-long love and admiration for Concorde, my best rose-tinted spectacles, a major dose of mad optimism and a trip into the fanciful - it will never (crying) happen.
For all the reasons above - bl00dy shame, but there it is.
On a more whimsical note - there was the most incredible thread running on PPRUNE a few years back, devoted to Concorde.
It became the most fascinating (100s of pages) discussion of just about every aspect of Concorde, and was priviledged to have a huge contribution from original designers, pilots, engineers etc.
The result, an absolute treasure trove of information about every aspect of the challenge of building and flying Concorde and how many of these challenges were overcome.
At one point in the discussion, the thought arose "knowing all of that, with the know-how still around and modern techniques, couldn't we now build a really efficient son-of-Concorde and it be much, much better?"
And this is a question I still ponder - do it now before all this knowledge and learning from the original is lost....with new materials available, 50 years of engine development etc - surely, it must be possible?
But no, reality will prevail, it just won't happen.
Of course, it could be done, but times have changed - imagine the up-troar (quite justified) from environmentalists etc...
I'll have to make do with the 47 models of Concorde I have at home, from 3 inches to 3 feet long!!, in wheels down and wheels up configuration, in BA and AF liveries, made of metal to wood.....
Concorde RIP - the most amazing machine to grace our skies
