Got a few points to make so pardon me if this goes on.
Last item first. Based on my time spent in and around aviation and the combination of visible cloud features and what could be mountain peaks just below the horizon/top of cloud cover at the midline of the photo, that picture was probably taken at or above 30,000 ft AGL (Above Ground Level). If it was presented as taken from AF1 at 40,000, I see no reason at all to disagree.
The "object" inside of the "Q" could be, JMHO, either a plane or missile as you contend. The only negative indicator about the "object" being a missile is the lack of exhaust plume which should be especially pronounced in the terminal guidance phase of a missile attack on an aircraft. (More on this below.) Since my only objection to identification of the "object" as an aircraft is that I can't recall any less than TWO military aircraft going on missions (outside of ASW patrols), I'll have to claim that the "object" is, in fact, an aircraft plus bow to Q's identification as an F-16, even if I'd have sent F-15 or F-22 for a job this High Priority.
Back to the beginning of the tale: While suborning an entire SSBN to launch a Trident/start WWIII to force Trump from office (which I count as Extreme High Drama but really kinda silly), a simpler and far more effective means could be the launch of an SM-6 Standard surface-to-air missile

to, at least implied in the words of John O. Brennan, "...To allies and friends, be patient. Mr. Trump is a temporary aberration. The America you knew once will return."
Conclusion: I may be less than charitable in my characterization of Brennan, but JMHO, if that POS didn't issue the orders to try and kill Trump/AF1 in June he damn well knows who did.
Obama, Clinton, Clapper, Brennan
I agree.
I'm thinking (and it might have already been posted in this long, long thread) that there was an order that came through the Chain of Command, but that that CoC was spoofed. Perhaps someone injected an order as though it came from the top, but in reality, it obviously didn't. If that's been traced back, you can bet that the access was immediately cut off. Someone would have had to have high level access and some know-how to do that.
