Infrared video readily records birds, insects and even the smallest meteors. However, this video shows objects at altitude moving in a very steady formation. We have been unable to find any species of high-flying bird that might fly like this, and these object do not have the footprint of planes, which generally offer a much brighter return. Still, it’s impossible to be certain that they are not something conventional. The smaller objects flashing past are probably meteors or birds, but the higher formation remains an unknown.
