L-shaped contrails

Sorry I haven’t posted much lately. I’ve been run off my feet with work. Like that woman at the end of Twelve Monkeys, I’m in insurance, and work is pressing. But anyhow, very briefly, I wanted to show you something I saw yesterday evening: L- shaped contrails. At least that’s what they looked like:

There appears to be two, one lower, one higher. Here’s another picture I took a few seconds later:

I was in Poole looking west, at circa 18:53 GMT.  Interesting, that!

    1. A paper on aluminium poisoning in India? I think you’e on the wrong website, Navid. Especially since the 1930s is nothing special. It gave us Born-Infeld theory, which I think is pretty good. But it was studiously ignored by the Copenhagen School, and now nobody knows about it.

    Interesting to think why the contrails split off at right angles? Such clean,straight lines. I’m sure there are some solid meteorological and chemical explanations as to why.

      I’m sure there’s some solid physical reason too. I don’t believe in magic. I was wondering if they were left by a couple of F35s doing vectored thrust, But then I thought they wouldn’t be able to shed the East-West velocity instantly. Or should that be North-South velocity? That’s if they are contrails of course. And of course, I thought I shouldn’t mention this sort of thing.

    In a moment of sibling love, against my better judgement, I allowed my only brother John W. Leslie to sign me up to Peter Mandeville’s UFO F.B. page. The one main bone of contention that I pick with all the others on UFO sightings is exactly what you stated: how does one defy wind resistance,gravity and inertia? The only answer I can come with is: Light ! Photons and electrons in the form of holographs? Perhaps an advance counter measure by our military to confuse the enemy? Or if it is extraterrestrial in origin, perhaps scientific probes? Pure speculation as always, but me thinks in a more logical manner.

    1. The physics detective

      I’m not sure about the wind resistance Greg. But I would say this: if you can defy gravity you can defy inertia. The man in the falling escalator doesn’t feel any downward acceleration. As far as he’s concerned, it would appear that there are no forces acting upon him. Of course that sentiment will end abruptly when he hits the ground!

    2. physics philosophy

      I once saw a UFO in an area the locals say they are quite common, and I regret not asking what the other UFO sightings in the area look like. What I saw looked more like something you might see in a plasma tube than an aircraft or an alien spacecraft. It consisted of two luminous red balls with tufts, each circling around a center point-they slowed down and sped up in their orbits once every second or so. They were connected by a what looked like a plasma streamer and were pretty close to eachother, probably less than the circumference of each ball. The whole phenomenom drifted across the sky at a slow, constant speed and eventually moved behind the treeline. Maybe it was “dragged” along by a charged cloud discharging through it into the ground, like a piece of pointy metal between the two electrodes of a giant static machine?

      It seems to me that all UFO sightings are probably some form of atmospheric electrical phenomenon. The hallucinations from high intensity EM fields, the sudden movements too fast for a physical object, the glowing balls of light or glowing clouds, and the mirroring of the motion of aircraft all seem to suggest this. Even the silvery disk shape might be a plasma with a really smooth boundary layer, which would cause it to reflect light like the electrons in a metal. I think that a number of “silver disk” sightings also include the disk splitting into multiple smaller objects, transforming into a glowing ball, or changing shape, even passing through solid objects like ball lightning, all of which a physical craft cannot do. Plasma, however, can do all sorts of incredible behaviors, far more than most think.

      There is a long list of atmospheric phenomena dismissed by science untill the evidence is too strong to ignore: ball lightning and upper atmospheric lighting come to mind. I would wager that eventually UFOs will join their ranks.

        You should talk to pilots.

    I spent many hours at altitude and many years in the Great Sonoran Desert. You see lots of very strange things when the air is clear and dry.

    I don’t think they are contrails, as in produced by aircraft. I think they are natural cloud formations. Just not very common ones. I have not seen this formation before but I have seen clouds forming along the edge or air streams that roll and I would think you have seen a rare occurrence of that happening in two directions. More than that I cannot say at this time, but it is an interesting observation.
