The problem isn't creating an aircraft that can do it—it's getting a carrier to put these into service. If this was financially feasible for carriers to fly, Boeing, Lockheed, Airbus, or Embraer would have created one. The technical and engineering aspects aren't beyond their abilities, it's all about if United, American, Delta, Air France, Virgin, etc will actually purchase and use the planes.
EDIT: I wanted to do the right thing and follow up this comment with the news that Virgin optioned ten planes (http://techcrunch.com/2016/03/23...). It's a good start and a good sign for the company. Optioning isn't a sure thing, but it's the right first step. Congratulations to the team for that!
@mscccc SF/NYC on our airplane would be just under 2 hours 20 minutes. But not until supersonic flight is allowed over land, unfortunately. So for now, we're working on long haul international, routes like SF/Shanghai, which are mostly over water and a big speedup can be had. (We'll fly Mach 0.95 when over land, still about 10% faster).
