The current thread about the 380 remided me that, before the SC, Boeing talked briefly about a BWB plane as long as a 744 and capable of holding up to 800 pax, I think with a range of about 7,000 nm. It looked like a mammoth B2 bomber. I have also seen sketches of similar Airbus proposals that were posted on this site.
So, where are they now, especially the Boeing proposal? Still too far off? Does anyone think the A380 will be the last tube and wing plane built?
