OK, Boeing only mentions mach 0.95, but many think that this will in fact be a supersonic plane. >From a certification and regulations point of view, what would be involved if Boeing decided to uprate that plane to Mach 1.5 ? Would there be a major difference in terms of FARs , regulations and approvals ? Also, Airbus stated that it needed to build 250 of the A380s to break even. What sort of numbers would Boeing have to build to make its Sonic Cruiser a money maker ?
