Here’s what NASA has to say on it:

Another Take on Supersonic

Our ability to fly at supersonic speeds over land in civil aircraft depends on our ability to reduce the level of sonic booms. NASA has been exploring a variety of options for quieting the boom, starting with design concepts and moving through wind tunnel tests to flight tests of new technologies. This rendering of a possible future civil supersonic transport shows a vehicle that is shaped to reduce the sonic shockwave signature and also to reduce drag.

Now, what do you think about supersonic civil aircraft?  I don’t think sonic booms should be such a big issue.  I grew up hearing them, and I’m just fine.  (twitch, twitch)
