Yeah, that’s where my questions start. First, the notion that ground control didn’t have eyes on even the sneakiest plane on the planet, is just not believeable. Then, when the thing went on the roll, tower flight control had to acknowledge it. One doesn’t get to be sneaky and off the scope when taxiing to the threshold——that would get people killed by the bunch. Tower does not say: plane that I can’t see cleared for takeoff. In every airport I’ve ever landed at flight control goes out at least five miles. If this pilot was trying, by accident or on purpose, to sneak past his own flight control guys the radio screaming should have already started.
Unless, of course, Comrade Milley’s F/C guys are so bleeping woke they don’t want to hurt anybody’s feeling by yelling at them on the radio. In this case the proper pronoun for everyone involved would be “dumbass.”
Ground controllers don't always watch, Tower does. He was airborne away from the field, departure may not have had him. Doesn't explain the punch out, does explain how the ac wasn't tracked afterward. Pretty stout to take an ejection and still fly at 1k. Had to have some severe aerodynamic disruption.
