I seriously doubt this thing can maneuver when traveling at its operational speed. Air resistance would be like hitting a brick wall, it would rip apart. Of course it can probably just fly past everything so fast that it doesn't matter, including air intercept missiles.

It must just eat fuel. I wonder what its expected operating range is. I bet it has to refuel inflight as soon as it gets off the ground and up to cruising altitude, before it can go do anything useful.
