Well, they are at a higher altitude than jets you usually observe in binoculars. Do you know for a fact that they are unmarked, and not merely too distant to make out markings even in binoculars?
People only two miles away from the WTC on 9/11 claimed they saw an unmarked, windowless jet strike the south tower. They were probably closer to that jet than you are to yours, and they couldn't tell the difference between a United Airlines passenger jet and a military cargo plane (presumably).
That is, they fly back and forth across the sky until their persistent contrails are streaked all over the visible sky like a kid fingerpainting on a paper.
You know for a fact that these same jets are flying back and forth across the sky? Have you actually observed them, in your line of sight, turning around and flying in a criss-cross pattern over your neighbourhood, or have you simply assumed that a plane that drops over the horizon is the same plane that comes back up a while later?
These leave contrails that do not dissipate but persist and spread out to form something like large bands of clouds that will block the sun on a day that was only a hour or two before a clear blur sky day.
As I said, if they're modern commercial jets, that is to be expected: that's the way high-bypass turbofan engines work.
If you can explain what these unmarked white jets are doing, I might believe the EPA feds who came out on March 13 and said we at EPA are not aware of aerial spraying of chemical aerosols from jet aircraft.
If the jets are in fact carrying passengers from point A to point B, then it makes perfect sense that the EPA is not aware of them spraying chemical aerosols into the upper atmosphere.
I put about as much trust in the EPA as i do in Obama. Funny they didn’t deny there is any spraying going on.
If one were inclined to extend the benefit of the doubt rather than view the EPA's statement in the worst possible light, one would notice that it is worded carefully to allow for the possibility that someone is spraying chemicals without their knowledge.
I'm not saying that the unauthorized spraying is actually happening—merely that it would be bad form to have gone on record denying something categorically that turned out to actually be happening. Hence the weasel words, assuming you have reported them accurately.
Criss coss, back and forth, like a lofty game of tic tac toe. I see what I see with my eyes and a binocular assist, and I reported it here. I don’t know what they’re doing up there, but I sure would like to know.
