There’s always been something disturbing about public internet advertisements of military equipment. I suppose it’s dual use, but it seems like baiting a malicious actor to play with it in detail.

If you're ever in DC, you should check out the ads in the metro stops near the Pentagon. Seeing those kinds of ads in real life is even more shocking.

This is something the military, e.g. fighter jets worry about. The altitudes (in a given airspace) that form contrails are briefed as part of "tactical weather". You try to avoid them if able, because no matter how stealthy you are, you are lit up for all to see if you fly at those altitudes.

This seems pretty useless in an age with super cheap 8k cameras and novice ability to do a delta-recorded image.

You don’t understand conspiracy loon logic. By the very act of hiding the chemtrails you are demonstrating that you are doing something nefarious.

Plus, the invisibility of a thing does not stop the conspiracy loons from building conspiracies around it. 5G RF is invisible, yet still being used by the government to control our brains. For chemtrails, the conspiracy is just going to turn into: "They're spraying invisible chemicals all over us to turn us into communists." There's no end to it.

> 5G RF is invisible, yet still being used by the government to control our brains.

Well it's one of the main last-mile mediums people use to doomscroll their propaganda feeds, so... yes?

What do you mean by delta-recorded image?

If it were all that simple would you not expect at least one of China, Taiwan, Iran, Israel, Ukraine, Russia to deploy such a technology? To me this recently popular idea that you can just point a load of cameras at the sky to beat stealth is disproved by the lack of such installations. These are fairly motivated actors.

Could you clarify this?

The fixed resolution of an image sensor can be augmented by capturing multiple frames over time.

> in places near busy airports I hear that a sizable fraction of all cloud cover is due to lingering contrails Hmm. I don't know about that. My understanding is that contrails only (or mainly?) form at higher altitudes. Most of the traffic around a busy airport is low-altitude take-offs and landings. I live practically next door to a busy international airport and can't say I ever notice contrails, except for a few o…

Do you ever see this kind of sky https://www.spiegel.de/wissenschaft/technik/kondensstreifen-... ? That's over Frankfurt, Germany's busiest airport. Also from the 2020 article (v. G. tr.): > Researchers believe that the ice clouds created by contrails have contributed more to the rise in global temperatures in recent years than all the CO2 released into the atmosphere since the beginning of aviation. The annual incre…
