Refueling liquid methane is risky business and how difficult it is to run a pulse-jet at low altitudes and speeds.
SR-72 has a nice UAV design. I wonder if it is autonomous or semi-autonomous, because they'd better have a plan if EMP or a solar flare knocks out our satellites. I imagine the flight-profile is easy enough as long as it doesn't need refueling.
