Add to the fact that if the missile was a heater it would have been tracking (drifting) to the rear quadrant of the target aircraft immediately after launch. If the missile was a radar guided missile then the aircraft is not on the CATA and also the missile would have been tracking on a lead/intercept track immediately after launch instead of aimed straight at it.
This is nonsense.
and why would the aircraft be in focus? not fuzzy at all
