Yes the TEX are trainers (flight training for military pilots). Their location and quantity and movements are not considered very significant by planefags.
I took a quick look at some of the images captured there. In-your-face, blatantly pedo.

and downloaded.
Maybe a few anons can also archive that thread.
I would assume there's a competent flight instructor in every trainer plane.

Looks like halfchan is actively investigating.
I'm not digging into this, but hope a digger will pursue it.
My conclusion this morning: Likely some kind of SpaceForce-type activity occurring in near earth orbit or where it could easily be observed as the spaceships transit the sun. Military activity in space, /ourguys/ need for it not to be seen/noticed by the public. Closure of observatories, although suspicious, will not arouse nearly as much suspicion as what would be seen if the observatories remained open.
It's on, anons. It's on.
