Read this guys:
New supersonic executive jets dubbed the 'Sons of Concorde' are being developed.
The imminent resumption of commercial Concorde flights has encouraged companies to develop smaller supersonic passenger jets.
Engineers and designers for companies including Boeing, Lockheed and Nasa are drawing up blueprints for planes which would be cleaner, quieter and quicker than Concorde.
The next generation of supersonic aircraft could be taking off in five to 10 years, The Sunday Telegraph reports.
A top-of-the-range 10-seater supersonic business jet could cost about £60 million, according to industry estimates.
Concorde is not allowed to fly supersonically over land because it is the world's dirtiest and loudest commercial aircraft. Its sonic booms can shatter windows and damage buildings.
Engineers believe they can produce a new generation of aircraft that will be quiet enough to allow them to fly supersonically across land.
This will be done by extending the nose and tail sections, "flattening" the pressure waves created when a plane passes through the sound barrier.
Peter Coen, a spokesman for Nasa, said: "We already have a sonic boom that is a quarter of Concorde's. That may not be quiet enough but we can cut it even more."

Wouldnt it be good if some of you could do designs for new Concordes, then post them here, and we'll think about them and discuss them
