I guess this thing will fly as a drone because there are no cockpit windows for any human pilot. That sure will make navigating an airport taxiway tricky unless they will be using IFR on the ground.
Not necessarily. NASA is researching windowless cockpits for future supersonic transports. The weight and complexity savings are huge if you can eliminate any kind of moving nose piece.
