And finally, to bring us full circle back to my original post...

look again and pay close attn from around 0:32 (just before and after one plane goes 'off'). To my eyes, those trails are mingling. Though ofc, your eyes may not see it the same way. Discount the 6000 ft thing as you are ofc correct, there is no way of telling from that vid.

I know what you mean, what I'm getting at is theres no obvious way of knowing altitude of both planes in the vid, one could be quite a bit above the other so there could be temperature and/or humidity variation which does cause contrails to appear and disappear, especially if the plane was making a turn at the time too which it was in the vid.

It could perhaps be turning a spray off and back on again on a new path but why bother? For that matter why would we even see the chemicals concerned as I mentioned before we have to assume its visible...whatever it is and we don't know that for sure either

Is it weird..yes, impossible to explain no so we're at square one again. I hate the topic, I know for certain there is some nefarious crap going on with it but so much speculation and its so hard to get any decent stuff on it.

Agreed, it is a difficult subject, fraught with pitfalls. It is one that needs discussion though, even if it ultimately merely leads to an answer, "no, it's just contrails" (which would actually be my preferred answer).

Any thoughts on t'other vid I posted? The 34k ft one?

Thats a better one provided the audio matches, I know that contrails can and do form at high altitudes (even 36000ft) but 'should' be much rarer. In fact you'll often more than not, see planes cruising at altitude with no contrail at all.
Did seem heavy for that altitude, couldn't see if it persisted though which would have helped.

Again, it is not provable that the video isn't faked in some way. But, taking it to be fo shizzle the video shows non commercial tankers that seem to be in and around the airspace of commercial flights with the pilot of the commercial flight having no prior knowledge of their presence. He requests advice over the radio. The trails are indeed very thick and do appear to be starting very very close to the engines, unlike classic contrails which form further back in the wake (though I concede this is not totally clear in the vid).
