As there are clearly so many thousands of these numpties about does it not seem a tad surprising that none of them have ever had the notion (hmm, no, I see the fault in my argument right there) to rent a learjet and borrow a likeminded chemistry PHD stude with a mass spectrometer and go fly through these things, and see what they find? Easy as pie. Of course the results would not make the exercise worthwhile, as they know in reality, so they just stay on the ground and bleat like sheep instead.
What is interesting too are the differrences in culture between these fora and the Chemtrails one, where dissent is forbudden and will be erased, pilots are specifically forbidden entry and logical argument is scoffed at in favour of blind regurgitation of the "company" line. A bit like some churches, I suppose...
Sad, really, isn't it?
