But the missile lost track of the drone and locked in on 800..."
Rconawa, as a fellow military pilot, you can read the above and appreciate why I asked you what your experience in this topic is. When some people believe ATC radars can pick up targets as small as a SAM missile, that the military conducts weapons systems tests amid civilian traffic, and that semi-active radar guided missiles can lock on to targets other than what their fire control radars are guiding them to explains in part how conspiracy theories like this one continue to exist.
I have read in several posts SAM that implies suface fired missile. What about AAM (air to air) fired from an aircraft?
