The Air Force made no such claim though. The paper you refer to was a War College what if paper. IF the technology existed, how could we use it.
Of course the planes are creating man made clouds. I never said they were not. But contrails aren’t geoengineering. As for crossing, there are thousands of planes in the sky at any given time, so of course they’re going to cross.
Yes. Crossing at 90* angles, nearly always the same altitude, filling the sky with a man made cloud that does not disburses but holds together as it sails the jetstream.
As for technological advances. It does look like they no longer have to rely so heavily on Evergree Air.
There is something about the emissions coming out in pulses that must be helping accomplish some of their goals.
I may be wrong and there is a logical explanation why jet exhaust is now coming out in pulses like a sputtering engine.
I have been watching a science lesson in the sky since the early 90's.
It fascinates me still to this day.

That would be why they are called “persistent contrails”.
Evergreen no longer exists. And I assume you are talking about their super tanker. That had nothing to do with spraying anything but water or flame retardant. It was a firefighting modification.
Exhaust isn’t coming out in pulses. Once the contrail is laid the air pushes it around and it starts to get pushed around by air currents.

That one sat in Pinal Air Park for years after they retired it. They modified a -400 but USFS wouldn’t certify it for more than on demand contracts, so they gave up after a few trades m years, and converted it back to a freighter. There’s a former a Northwest -200 they’ve been working on for years, but I don’t know if it will ever get off the ground.
