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.
