I was looking around the net and found a peice of information that said:
Airbus began engineering development work on such an aircraft, then designated the A3XX, in June 1994. Airbus studied numerous design configurations for the A3XX and gave serious consideration to a single deck aircraft which would have seated 12 abreast and twin vertical tails. However Airbus settled upon a twin deck configuration, largely because of the significantly lighter structure required.
This "twin deck configuration" ended up as the A380 of corse but i was wondering if anybody out there has ever made a model of the " single deck aircraft which would have seated 12 abreast and twin vertical tails." I think it would be interesting to fly and i for one would love to download it.
Another thing i've been dying to get my hands on is a decent set of Air New Zealand aircraft b747s etc and finally heres something to appeal to your more creative side. Theres a lot of aircraft out there that are completely made up and that have never existed even in prototype form. Why not make something that is both realistic and completely made up if that makes sense. Make the next generation of airliners. Be revolutionary but keep it realistic why not see what you come up with
