What does not inspire confidence in me is that they are toying around with what appears to be a small General Electric CJ610 turbojet engine, developed in the 60s from the earlier J85. Doesn't seem like the best propulsive plant for a supersonic airliner!

A CJ610 engine doesn't have complicated electronics to integrate, and would allow aerodynamic test data from a subscale model. For comparison, the two J85 engines in a F-5E could push it to over M1.4 at altitude.
