A Pilot's Perspective

33 Minutes

Dr. Kevin Stillwagon is a retired airline pilot with a scientific mindset who has observed, and in fact created, the "white lines in the sky", also referred to as chemtrails, contrails, and vapor trails.

This video is an exhaustive explanation of the phenomenon in a very rational manner. Dr. Stillwagon explains that what we're seeing are not the result of special chemicals being sprayed during flight (although there are cases where this can occur, but we wouldn't see them) but are an effect of a combination of newer jet engine designs, atmospheric conditions, and changes in the amount of traffic and navigation planning over time. The video includes many photos and videos (some here on this website) that claim to "prove" a particular point, and he walks through each one and explains the problem with them.

Dr. Stillwagon stresses that there is still a danger related to these visual trails, but that we're going down the wrong rabbit hole. We should be focussing on reducing the visible vapor trails (which are blocking sunlight; easily done with minor changes during flight) and reformulating jet fuel (to reduce sulfur and particulates), similar what was done in the past with diesel fuels.

I strongly recommend watching this video; it's quite the education.
