For an alternative view:
Military coup was well planned and very nearly succeeded, say Turkish officials

There is already a plausible explanation coming out as to why the coupist fighters tracking Erdogan's plane did not shoot it down in that the loyalist fighter pilots accompanying it allegedly convinced them in radio communications that it was a domestic passenger flight.
I have absolutely no doubt that a coup orchestrated from the very top would have been able to overthrow Erdogan's regime without any trouble at all, so the conclusion must certainly be reached that this attempt was only staged by part of the armed forces. Reports of a number of warships said still to be missing are interesting, too.
Another conspiracy theory doing the rounds particularly in the Kurdish community is that the Kemalists tricked the Gulenists into staging this coup promising that they would then lend it their support, but then left them to their fate, because they also wanted to see the Gulenists purged from the armed forces and elsewhere. As I have said before, the contents of the statement the coupists made on state TV made it appear targeted towards the secular/Kemalist section of society, yet, as far as I can see, absolutely nobody in the secular community came out in support of it.
