The process of injecting aerosols into the atmosphere involves a lot of hardware. Hardware fails. It's a fact of life. Also, you're going to run out of chemical aerosol eventually.
This collection of photos and videos shows failing equipment, oscillating trails, and what it looks like when trails are intentionally turned on and off.
Sudden Starting and Stopping
Oscillations From Only One Engine
We have seen many artifacts of malfunctioning spray equipment. In this video, a pump or valve is oscillating causing a pulsing pattern in the emitted aerosols.
Many have spotted spraying start and stop. The government propagandists claim this is due to changing moisture content in the air, but nothing could be further from the truth. Historically, high bypass turbofan engines have never produced trails regardless of atmospheric moisture.
It's not uncommon to see trails start and stop abruptly.
About 2012, they begin spraying in short bursts to make the trails look more like clouds. Many saw this activity and quickly realized how hard they are attempting to hide the spraying from the public.
Whistleblowers have stated that pumps controlling aerosol dispersion are controlled remotely. This enables command centers to precisely release aerosols based on wind velocity and other atmospheric conditions.
In the following video, not only do the trails start and stop abruptly, but they are not synchronized. A whistleblower told us that trail dispersion (turning the pumps on and off) is controlled remotely. Even so, we would expect to see slight delays in the reaction time of the equipment on board, just as shown in this video.
This video clearly shows the moment that a lateral-wing dispersal system is running out of aerosols. Air enters the lines resulting in an intermittent pattern. Once the chemical-aerosol is gone, the trails disappears.
