It has been said, if you want to control the future, you must control the past, and indeed, today our tax dollars are being used to convince public that chemical aerosols being sprayed around the world are harmless. They are also attempting to convince the public that the skies have always been covered in jet trails.
It was inevitable that, eventually, they would begin to edit chemtrails in to old movies in order to convince the public that they have been around since jets have been flying, but they have to be careful, because in this age of YouTube and video archiving, they won't get away with it.
Below we see an early attempt to "normalize" chemtrails by adding them to a movie clip used in a commercial from a remake (1970) of the classic movie called "The Railway Children". This is likely a test to see if they can get away with it. They probably used this altered movie clips in commercials because they can simply shift the blame to corporations without it being labeled "propaganda".
As more clips from old movies appear on YouTube sporting chemtrails in the background, don't blindly believe these are unaltered clips. Until you see a true, positively-unaltered original, you won't know if the trails have been added in later or not. What we do know is historically, this is exactly the style of propaganda that has been used against the public.
Interestingly, most of the the newly-emerging movie clips with chemtrails were shot before high-bypass turbofan engines were in mainstream use. Even the Boeing 707 - which was developed and first test-flown shortly before 1960 - used low-bypass turbofans (called simply "turbofans") for decades, and it took years for turbofans to become the mainstream source of propulsion on airlines.
Please do not be deceived.
Let's be sure they don't get away with this historic crime against humanity. Please share this post with everyone you know.
