OK, for a BETTER eye witness report ... Do they have air to air missiles on their hard points; ie are there Sidewinders near the wing tips and larger missile along the center line area or mid-wing?
If they only have drop tanks or are really clean, they are likely up for show.
Correction to the hard points on F-15.
Sidewinders are mid wing, AMRAMs near wing root.
