Pitching in my own theory,

Theory 1
As CIT posits, a large aircraft flew over the Pentagon approaching from north of CITGO, then explosives create damage along the route described in the OCT.

Theory 2
1. a large aircraft approached the Pentagon via north of CITGO and corroborated by witnesses questioned by CIT
2. if it was a large RPV rather than an airliner, it could have impacted the Pentagon from that north angle, but explosives created the damage along the official impact route (south of CITGO angle) including the downed light poles to simulate a larger aircraft (a case of misalignment)
3. the RPV impact explains:
a. the engine allegedly photographed inside the Pentagon,
b. the small impact entry hole,
c. the small object flying in the released Penatagon video

Do I feel strongly about theory 2, not really, theory 1 is my bet, but I do not rule out theory 2 as of now.

I think CIT has done valuable research on the Pentagon, and I think it pretty much confirms that an airliner did not impact the Pentagon. I am less convinced at the moment though that theory 1 is the only explanation of what transpired. Further research and evidence would probably support CIT's theory or else lead to new ones. But I think that confirming an airliner did not hit the Pentagon is big enough a victory, just as free fall acceleration of WTC7, for me confirms that it was demolished, and details about whether nano thermite, or conventional explosives were used is a secondary (though still very important) concern that can be threshed out in further investigation.

I am not advocating that anyone rest where we are. Officials won't do any real investigating unless forced to. So citizen investigators such as CIT, Steven Jones, et al are our best source of info until such time that the citizenry take back their government from the perps.
