Still interested in the business model. Supersonic flight is over land is illegal in the US.

NASA is testing new supersonic designs to see if they can be quiet enough for the ban to be revisited.

There has been some openness towards reversing the ban.

But it doesn't look any serioys movement will happen until after someone makes a plane and proves it's quiet enough.

So Boom are taking a bit of a leap of faith, and also designing it to be capable of trans-Atlantic flights as a semi-profitable backup plan.

There is a procedure that allows supersonic operation under certain conditions granted on an individual basis. In addition, any new aircraft would need to meet current airworthiness and noise certification requirements.

Yes the link I posted mentions that.

> Currently, U.S. law prohibits flight in excess of Mach 1 over land unless specifically authorized by the FAA for purposes stated in the regulations. The two supersonic rulemaking activities would not rescind the prohibition of flight in excess of Mach 1 over land.
