Concerns with that are; the escort is probably not transponding and not “visible”; and, there is a TON of clutter in his path from all the training jets at various location.
My only indicator is the presence of K35R refuelers along and near the route.
Currently there are 33 refuelers with most of them servicing the trainers.
I’ll follow this post with The Boss (in pink) and K35R in the vicinity.
To my untrained eye, it is highly probable that he has an escort.
Can USSS request one for his protection?
As both an ex-prez and a current candidate the USSS can certainly call up escorts and in-turn, the escorts can refuel if need be. And Trump wouldn’t have to pay for the escort related services. Trump Force One has coast-to-coast range so it wouldn’t be in the refuel loop. On a c-to-c run the air around TFO has to look like a flying beehive?
