the F16 action in intercepting the aircraft had nothing to do with politics or who the owner did or did not donate money to.
If ANY plane violates Washington, DC, airspace without approval, it gets attention, especially if they fly over prohibited airspace.
Yes, this plane was too high to be within prohibited airspace, but it stopped communicating with air traffic control around fifteen minutes after takeoff, according to the newspaper. It certainly didn’t land at its planned destination.
The F 16 action may be due to concern about a hijacking, not who donated money to whom.
