Following on from the announcement and following order of the A350XWB, I was wondering about an A370UWB (Ultra Wide Body) single level aircraft.
Presummably this aircraft would be a quad (or perhaps a twin with engines running on steroids), and would require a fuselage width wide enough to accommodate 10 abreast in a comfortable 18.5" seat or 11 abreast with a 17.5" seat width.
What do you think, would this aircraft be a goer???
I'd imagine the capacity would be somewhere between the A340-600 and the A380 (of course would depend on the length).
