November 1998:
British Airways announces that it will not resume regional transatlantic services to New York from Glasgow and Birmingham for Summer 1999. Neither of the services operate in the winter season due to poor demand and financial performance.

Of course, this in itself is not likely to cause Boeing strategists to lose any sleep, but I think it is an interesting (and surprising) bit of information.
I think a far more relevant argument against the Sonic Cruiser would be to compare it, strategy wise, to the VC10, then to consider the commercial success of the VC10 (or lack thereof).
