how long will it be before we have another supersonic airliner?

sonic cruiser was not supersonic. several airlines did want it, but mostly US based carriers. then 9/11 happened, and the US carriers' interest dropped as their stock prices and ridership fell. fuel prices also started to ratchet up. boeing pointed out that the sonic cruiser could either be used in high speed or in high economy mode. they then basically changed the layout of the aircraft from the neat futuristic design to a more conventional one, resulting in the 787.

When they get around the following problems.

1) Sonic booms over populated areas (concord was forced to slow over populated areas because of this)
2) Poor Fuel Economy
3) Lack of passenger capacity
4) Ticket cost (actually a combination of 2 and 3)
5) Demand - Not many people actually need to get from New York to Paris in 3.5 hours instead of 8 hours. (also a function of 4)

Sonic booms only occur when the aircraft is passing through mach 1. There is no sonic boom as the aircraft slows down from a supersonic speed. So what I think you mean to say is the Concorde could not accelerate to supersonic speed until it was outside a populated area, which really isn't that big of a deal. Chances are the aircraft would not be traveling at supersonic speed until it had climbed to 30,000 feet anyway which would give them plenty of time to fly over an unpopulated area. Anyway, I'm just nitpicking. The rest of your points are all valid.

You don't seem to understand a sonic boom. As someone else said, the boom is continuous, traveling along below the plane as long as it's going faster than sound.

I didn't know that it was subsonic.
