The advertising Boom is doing with United claims they will be able to fly SFO-NRT and LAX-SYD [1]. But the Great Circle Mapper says SFO-NRT is 4453nm, and LAX-SYD is 6507nm.
The maximum range of the Boom Overture is 4250nm [2].
So is there going to be enough NYC-Europe supersonic demand for to make a Boom Overture 2.0 viable? The current state of transatlantic flights is pretty good with lie-flat seats and fast Wi-Fi.
