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 ?
