I had not heard of this theory until very recently and it took me by surprise as an acquaintance of mine suddenly starting explaining the issue and his worry. I initially thought he was pulling my leg, since it seems crazy on the face of it, but sadly he wasn't.

The idea that chems could be effeciently distributed in such a way, or that the plane could hold enough materials to itself carry and disburse such long trails, seems to me to be testable and verifiably false.

I strongly disagree that this theory holds any water.
