BA EZE-LGW
AJ,
Mindthegap suggested we don't write about things we don't know about.
Your suggestion that a BA flight continued after an inflight shutdown may be completely correct, but if they did continue, then I think you'll find it was a 744, not a 777 on ETOPS. That's why it's handy to have 3 or 4 engines.
I really don't think your comments contribute much to this thread. Why not heed the advice . . . and refrain from writing about things when you're not in posession of the facts.
