chemtrails and Black line phenomena

[jose v]

What is that mysterious black line occasionally seen running parallel to, or ahead of, chemtrails? When I first saw this I thought it was probably just a shadow being cast by the chemtrail. But I've seen the phenomenon several times when the position of the sun was such that it was obvious that the line could not be a shadow.

Some investigators think these dark lines are strongly indicative of particle-beams which would be greatly enhanced by the addition of aerosol metallic elements.

So far, it appears to be a mystery and we can only speculate on the reasons and causes.
