Was Trump in Florida on that weekend? Maybe that KC-10 was supporting the fighter aircraft patrolling the TFR over Trump's Florida home.
He was! I thought of that but couldn't think of why such a large unarmed craft would be needed to protect the area. I didn't think of it working in conjunction with smaller fighters on standby...
Lots of cool activity around here! The Goodyear blimp is housed just north of Fort Lauderdale. They take it out for a walk up and down the beach every couple days. Also a lot of international traffic to & from Cuba and the Bahamas. Fun stuff!
