As far as staff go, what is going to happen to the "ex" Concord pilots - do you think they'd be happy flying s***ty A380s? of course they wouldnt be happy flying anything less than concord.
To the point that if RB bought the A/Cs he'd have a load of ex BA aircrew suddenly joining virgin.
As far as technology goes - if the Mod took that attitude we'd still be flying spitfires (well that's good, but you know what I mean) the RAF have new fighters being developed all the time. So why not airlines?
Concord is a big big national asset.
Don't let it be scrapped. And remember RB is a pilot himself, I bet he would like to keep one of the concords as his personal A/C.
anyway, that's my two penneth.
