The reason planes don't do it all the time is precisely because the conditions vary. I've tracked flights and taken photographs myself when I was
looking into the theory.
In lower, warmer air no plane will leave a contrail. At cruising altitudes for civil aircraft between 28,000 and 38,000 ft it is always freezing cold,
minus 20 or colder, and so all aircraft here will leave trails. Here it is the relative humidity (RH) that makes the difference. When it is low the
frozen trail will quickly sublimate and the trail will disappear. If it is high and the air is already full of moisture and cannot take any more, the
frozen trail has nowhere to go and hangs around until that condition changes.
A plane seeming to turn a trail on or off is simply flying out of one condition into the other, no switch flicking is required for that effect.
By all means be suspicious and on the look out, that's how wrong doing always gets found out, all I'm trying to say in my long winded way is to try
and understand as fully as possible exactly WHAT you are observing so that you are equipped to identify nefarious activity when it happens and you
don't fall into the same trap as so many on here of just mis-identifying regular contrails which CAN persist, CAN stop-start and which pretty much
HAVE to form grids due to the nature of air traffic. In my experience you will always see a grid when contrails persist. And yes, I have photos of
That's why I ask what the reason is for believing, my personal theory is that people look on the Internet to explain something that looks odd to them
in the sky, find chemtrails and that's that.
If chemtrails are evidenced entirely from what the trail looks like, then I SHOULD have seen one by now. I have seen grids, stop-start trails, long
persisting trails that spread out, in fact ALL the classic descriptions we get on here, over a 40 year fascination with flying, but I still haven't
seen a trail that looks out of place based on what I know contrails do and have known since long before chemtrails were first claimed.
If people are ONLY convinced about chemtrails because they don't think that contrails should look like any of those things, then I believe they are
making a wrong call.
When someone then tells me I am a closed minded sheeple, unable to absorb facts, or words to that effect (not you, it's happened a few times from
believers not just the imbeciles that have done it in this thread) when i dare to disagree with them because I did my OWN research and used my own
knowledge and experience and combined it with all the independant sources I have access to, rather than simply take their word for it, or swallow the
rambling nonsense linked on some nutjob website, it convinces me even more strongly that the whole Chemtrail malarkey is a scam.
Here is an example image from my own research where I identified aircraft to eliminate "secret military" flights from the trails, the data was from
flightradar24, the photo is my own.
