Yes, very sad news, another great part of our aviation heritage to go, along with Woodford, Hatfield etc.
Don't know tho that Bristol showed all that much "commercial dyamism" in the 1950s tho-eg the Britannia, which was so chronically delayed that it missed the market almost completely, tho BOAC, I think (I wasn't around then) played a major part too, in the Brit's failure.
I would think the Concorde at Filton is in no danger: it will either stay there, as the centrepiece of a new housing estate (groan), or be moved elsewhere. No-one would dare to suggest scrapping a Concorde, in my view, in the UK at least.
