V shape 11 very huge white cotton ball type shapes above normal jet liner cruising elevation, appeared 50,000 feet or higher. first the v traveled nw to se for 3-4 minutes, then the lead sphere turned back towards the nw and the following spheres gradually turned with the 3-5 lead spheres turned slightly north and they all became similarly aligned perfectly. the v headed n/nw for another a minute and a half and then dissipated/disappeared. they were not birds, way way too high in the sky and the spheres movements throughout were precise, the turn back to the nw was almost like the back spheres moved north and just dropped straight back in line, appeared to be quick straight movement and when they were all lined back up, they all appeared linked together and under control of the lead sphere. tried to video last few minutes but camera did not record.
