Aviation lights is a joke. Actually, my guess is that what you are seeing is the tail end of a jet engine.. We used to live in North Richland Hills near DFW and you would often see these little glowing orbs that slowly fell, then often shot to the right or left.. what they where, where jet engines seen looking straight on from the back so they appeared to be floating or standing still when in reality, they where moving away, thus they would ‘slowly disappear’..
That’s just my guess based on the video..
