I took this video a few hours ago, just before that brief thunderstorm over Roanoke. This looks like one of those AWACS (Airborne Warning and Control System) planes that the military uses, doesn’t it? (See the dish-shaped radar device atop it.) It was circling the area.
I remember seeing these in the 1980’s as a kid on Long Island (along with plenty of F-14 “Tomcats” buzzing our neighborhood), because Grumman Aerospace had a major plant out in Calverton. They actually designed and tested new fighter jets there — which the kids thought was pretty neat.) The AWACS aircraft were the planes that could detect incoming planes or missiles from Russia. (Nowadays, Senate Republicans would block funding for that sort of thing.)
I suppose this could be a civilian plane … I can only imagine that the radar technology has other applications. I honestly don’t know.
