The way to get a Concorde is simple;
1) Is the area of the museum appropriate to the aircrafts history? (rules in UK museums by default).
2) Can the aircraft be displayed in good condition? So undercover really.
3) Has the museum the resources to look after the aircraft in the long term?
Now Seattle loses on no.1, but scores well on the other two, and they've a Comet there too which somewhat alleviates 1.
Brooklands fails totally on 2 and 3.
Filton looks great for 1, and should be OK
for 2 and 3, if 202 is moved off site.
Cosford should score on 1 and 3, I've not been there so cannot comment on 2, BA
will look at how AF
get their one on to that roof in Germany, possibly a Concorde could land at the nearest airport to Cosford, then dissemble and do the rest by road if possible.
Despite having a Concorde, Duxford are very highly regarded by BA
Cannot comment on the Scottish facility, if it looks good, then its got a chance.
What we really want is a decent place near New York, not the USS Intrepid, I understand that they are not favoured any more, like Brooklands.
