Brilliant is right ! Find something thats's similarly reflective to the crystals formed by a jets exhaust vapours. The Governments will have a simple explanation to disprove any asbestos or similar chemical structure (newly developed) form and confuse the masses once again...
Chemtrails: Spraying in Our Sky. Petition to Canadian Parliament. Government’s Response as to the cause of exhaust vapours from jets.
"The water vapour in the exhaust freezes into ice crystals which form the clouds that are visible from the surface. The relative humidity in the atmosphere in the vicinity of a contrail is the primary variable that impacts how long a contrail lives. When the relative humidity is fairly high (i.e. near saturation) the contrails can provide sufficient moisture to initiate a long-lived cloud. Strong winds will also affect the lifespan of a contrail by changing their appearance as they move. In some cases, contrails have lasted more than 24 hours. When the relative humidity is low and wind speed is high the contrail clouds of ice crystals quickly sublimate and disappear.
Contrails frequently spread out. This happens when the relative humidity of the atmosphere is fairly high, so that the contrail serves like a cloud initiation mechanism. The ice crystals grow by vapour deposition (the process whereby water vapour molecules deposit onto the surface of the ice crystals) and can also form new ice crystals from the nearby water vapour. These new ice crystals, in turn, can grow and form more ice crystals until the environment is no longer saturated."
