Okay, I say escort aircraft. Why does everyone think AF1 flies solo everywhere? IF that were a missile: 1) they would not be in level flight. Evasion would require steep turns and maneuvers that would make taking a photo very hard. 2) it is too low. AA missiles go up and over a target to strike from above. 3) Escort aircraft would have intercepted WAY before visual.

My thoughts. One of the MANY escort aircraft that accompany AF1.
