Even leaving aside the sonic boom issue (on which improvements have been made but it's unclear whether those are sufficient), it's just extremely fuel expensive. Maybe one day we'll power airplanes with nuclear fusion, but until then I can't see hypersonic flight becoming commercially viable.
However, a lot of you asked what's with Elon Musk's idea of a hyperloop. Does that make any more sense? And what's a hyperloop to begin with? On Saturday I'll give you the brief summary of what you need to know.

1: Other than "time", what is gained over a modernized rail system? 2: Given the investment needed by cities for all the working parts (to be acquired from Musk Enterprise), doesn't this need to be a replacement for the standard (or modernized) rail system? How can society afford both? 3: Is the already proven "Bullet Train" technology a better solution for the future?
