In 1999 to 2000, Boeing had a concept three aisle airliner that use a 777 section 42. The a/c looked a big sister to the T-7, like the 767 was to the 757. The a/c had four giant engines and carried around 480 passenger in a three class lay out. I know this concept is over and gone, but I would like to copy a drawing of this concept airliner, but I can not remember it's name, so could somebody please help me out?

Quoting seabosdca (Reply 7): Was the 747-700X intended to have three aisles on the main deck? It was a 747 derivative with an enlarged 777-ish wing and a widened fuselage incorporating a twin-aisle upper deck.
The 747-700X would have had a 1.5m wider main cabin (7.6m total), so I can only guess that they would have gone three aisles as you would not need 1.5m to go 3+5+3. However, I have never seen an internal schematic of the 747-700X nor does the information I have on the plane note the internal configuration, just that it could seat up to 650 in three classes.

Quoting deltamartin (Reply 5): Speaking of VLA's, wasn't Airbus first thought for the A3XX (later A380) to basically put two A340 fuselages next to eachother and weld em' together?
Quoting Stitch (Reply 6): Yes, Airbus had a number of proposals for aircraft with side-by-side cabins within a larger fuselage structure, but these predate the A3XX (which looked very close to the A380).
Here is a picture of the Airbus UHCA:
