Found this as part of a thread over on reddit.
I gotta say, this is pretty egregiously absurd for the simple reason that this person allegedly saw incredible orbs flying next to the airplane, but seems to have made no effort to say anything about this to other passengers. Also apparently no one else was looking out the windows or took any notice of this whatsoever given that there doesn't seem to have been a big news story about a plane of people all seeing dazzling orbs.. The video was just dumped with essentially no provenance om youtube and that's that.
To me these "orbs" look very much like they're done using pretty basic special effects in something like aftereffects, very undetailed and simple blobs of white light.
