Triangle Formation Of UFOs Pass Swiftly Over Russia! Is It Aliens?

This might be old but I've always had an interest in the triangle formation that appear worldwide, what I like about this is how high they are and yet they are perfectly aligned while keeping a static shape while moving swiftly across the skies over Russia. Recorded on the 13th of April 2012 the sighting is among the best from Russia of the triangle formations. Hard to say these are lanterns unless you tie them together, but tying them would result in the spinning or twisting! these dont. What is your thoughts on this strange set of lights?
