Saw one in upstate NY during the time of the Egypt/Israeli thing, as I recall.
Small and low footprint but massive purple flames taking off.
Have you never seen one up close? They’re HUGE! for a 2-seat aircraft.
When I was stationed at Beale one of the things a lot of people loved to do was sit on the hills above the flight line and watch the engine burnoff after she landed. They had a pad the plane would taxi to and they would then open the engines up and burn the remaining fuel off. It was a hell of a light and sound show! We would call it the sound of freedom.
