I have seen this many times as well. Altitude is very difficult to observe from the ground. Using the UHF and VHF radios and altitude data from those sources it is explained by planes flying at different altitudes.
There can be large differences in pressure and temperature over even relatively short altitude and location differences.
The same goes for the 'stopping and starting' trails. Everything filmed I have seen is clearly contrails. I am skeptical on this topic so I frequently visit pages claiming to have new evidence.
i appreciate that the scenario you describe is something that needs to be ruled out - however, from what i have seen - there are some cases where significant altitude differences are unlikely. the KLM pilot describes the conditions necessary for contrails to form and states that they are not especially common in the context of commercial jets. that would appear to make extremely questionable, both the common site of entire skies being clouded over with thin material that has been filmed to have originated only from the rear of jets and the other phenomena that are often written off instead of the observer remaining open to what they may not already be aware of.
i do not know the answers 100% in 100% of the cases, but I have seen more than enough evidence to know that 'chemtrails' (or whatever scientific buzzword is being used) do exist - the only question for me is to what extent and for what purpose.
I disagree with this entirely.
They are spraying in some areas of the country. To what extent - well, they are certainly not spraying from commercial airliners.
I'm going to stay skeptical.
i don't see any reliable evidence that commercial airliners are not involved - obviously neither of us monitors the activity of all commercial flights.
I am not saying that I do but from a strictly logical standpoint - there is no reason to use commercial airliners.
There is no room for any holds of material on commercial airlines. It would make all the sense in the world to use military aircraft. People have looked into the commercial airline industry much deeper than I care to and I haven't seen anything that seems to indicate the possibility of commercial airlines being involved.
These tanks are not what the conspiracy theories say they are.
the issue of the tank images being mis-represented is well known. While there are images of ballast tanks being distributed and falsely represented as chemtrail tanks - there are also images (linked in the original post i shared in this thread) which appear to show actually spraying tanks too.
the picture you have chosen is not one i have investigated - but you gave no reasons for saying that the image is not as the meme you posted claims. why are the tanks not what other researchers have claimed they are?
what about the other images here: http://awarenessact.com/32-photoss-from-inside-chemtrail-planes-like-youve-never-seen-before/
There is a collection of actual areal spray equipment- mostly on the military aircraft. Lots of firefighting equipment and ballast tanks.
