Does no-one else have a sense of deja-vue?
1) If its a European design, will the yanks admit it into the US? (witness the relative lack of progress on updating US airports for the A380)
2) With oil at $60+ per barrell, can it make money?
3) With 250 seats, do the heat expansion problems and commercial viability still work?
Its a nice idea, but until there is gound breaking news on the fuel economy, a burgeoning western economy, and a buy-in from the US, frankly I doubt it....
