Sorry dude, you're like 5 years behind....Here is one of my favorite recent sketches. It is an idea I came up with the other week for an ultra large transport aircraft (over 300 ft long) designed to carry either silly amounts of cargo such as tanks, or even act as a mothership for up to 10 parasite aircraft.

Also been thinking of how feasible it would be to turn it into an airliner. I am gonna have to model this one sometime soon...

I can't find it on the web but there's a feasibility study on the Uni computers that takes everything from a cargo version to a ultra-high capacity passenger airliner and takes into account evacuation procedures and everything.
[EDIT] Much like the Nasa BWB.
