My initial inquiry seems to have spawned more questions in my mind.
I'm not that familiar with the differences in later Boeing and Airbus models. If no Airbus in the BA fleet could make it across the Atlantic, then the B7x7 is an obvious choice.
Regardless of BA ownership, what Airbus models regularly fly the Atlantic? Is it just the A340?
True, most Americans think of the Airbus as French, but it is a consortium, is it not, of which the UK is a part? And wasn't this consortium an outgrowth of the Concorde SST effort? And isn't British Aerospace's major contribution the wings?
Finally, the abbreviation BA could mean both British Airways and British Aerospace, so how is the latter distinguished from the former?
I appreciate the answers and insights that all of you have shared with me in this and other threads.
