obviously i agree about the sonic boom thing... but aren't a huge number of the world's most lucrative routes over water? basically the entire east coast of north america to nearly all of europe, and the entire west coast of north america to most of asia...
the real issue is the cost of fuel and the inefficiency of flight at such high speeds, i think.
