This video from 2014 is by all indications authentic and quite unusual. It shows a small oval object that fires pulses of energy into a contrail. The composition of the contrail, and the reason that the object reacted in this way, are unknown. It could be that the contrail is not actually the reason that the object is firing the pulses. In any case, video of a UFO doing anything remotely like this is almost always fake. There is no indication of that here.
Rated A-Probably True.
