Comment Re:So no planes are to fly over Tennessee? (Score 1) 202
I can at the very least attest to the fact that jets used to leave the exact same trails when I was a kid. I'm also from a very rural flyover state so I spent most of my childhood outdoors with my bb gun or stomping around the pastures. I vividly remember in the late 80s and early 90s the planes going over (there is an international airport an hour's drive from my parents farm). Then, as now, they had thick white trails that would start out very small and tight and gradually get wider. If the plane was low enough and it wasn't windy, I could watch them for a very long time spreading into huge fluffy long clouds. I obviously am not sending up weather balloons and taking samples of it, but it looks pretty much like normal cloud so these days I assume water vapor like I do now.
Growing up a classmates dad was also an air-traffic controller. He once came on career day to inspire us and talked a lot about how it worked. The main things I remember were that you have to space out flight plans and also that they have some horrid three strikes rule where if any two planes on your watch ever become indistinguishable as a single dot on radar you get a strike whether there is a collision or not. Three strikes and you're out of the air traffic controller business for life. So - rather than inspiring me I never wanted to be an air-traffic controller.
There was also an old-timey festival in our neighboring small town where they'd get out steam engines and thrash a field using pre-tractor era farming techniques. A sideshow event of that was a small single-propeller aircraft you could take rides in. Depending on the time of the day the coolest thing about that plane was that when it was running on the ground it would make these white spirals in the air around the nose of the plane and as a kid that was the coolest thing ever. When it took off, they'd continue and it would leave a white trail too - but it didn't really look quite like the ones that the jets at the airport left. It was more like:
| | | | | \ | | |
At first (from below - it would fly right over the festival grounds). After a minute or two it would spread out enough that the pattern wasn't really as visible anymore but it would still look like a long cloud.
I know it wasn't the exhaust because I could see where the exhaust was coming out of the tailpipe which was kind of down and below the airplane.
This didn't always happen, and was more common when they did the morning flights than the afternoon ones. I don't know why, maybe the warmer day air was drier? In any case that dude wasn't in on some chemtrail thing; he was just a farmer dude whose land butted against the festival grounds and he had a bulldozer so he made himself a grass runway and when that festival became a thing he started selling short flights with his little plane.
So at the very least - I know it's possible that one can do the whole contrail thing at LEAST with a propeller plane since I've seen it first-hand. I presume a similar principle can apply to jet engines but that's not a firsthand assumption.
As to the KC-135 aircraft refueling thing - the only speculation I have is some kind of military nonsense. I know some transport aircraft are disguised as passenger planes to avoid being shot down in clandestine delivery operations so it doesn't sound unreasonable to me that you're correct about seeing the refueling of passenger aircraft.
