content: right payload of a an-225 is almost exactly twice that of a 777.  the 225 cost about the same to build as the 777 so we could haul 600 people per plane.  if they can recommision the Concorde then there must be enough people going from the states to Europe to justify the concorde.  So why not a super big ass plane? If could just go big airport like Chicago to some place in Germany or something. Major hub to major hub.  Would be like the Megabus of planes.
