Have you considered that the doughnut shaped contrail migt have come from a knew type of aircraft engine? Obviously the Aurora is sleek,fast and has a low radar crosssection BUT what if all of that were Ho Hum compared to a completly new propulsion system? One that is not based on any jet fuell we know. But rather an energy force that untill recently had only been hypothetical. Interested ?
