#Repost Chemtrail Pilots Club This is a manoeuvre that you don't see every day!Images have just been released of the joint EU-NASA efforts to develop verticle trails!Technically called Vertical Wind Sheer Dispersal technique, it is a method developed to take advantage of wind currents at different altitudes.Counter-intuitively, it actually achieves a much great spread and coverage as these high altitude wind currents can disperse in various directions at the same time. With some calculations, one aircraft can cover a much larger area!Whilst you'd be pretty lucky to witness one of these today, hopefully we will see many of them into the future.
