There is one more explanation, and sky spirals have been thought of as "UFO" related a few times.
There is a classified type of airplane chaff with this result.
For decades, missile deterrent chaff spewed, out of the aircraft, as a defensive measure for itself.
However in the past few years at least, since the Norway incident, a deterrent chaff has been developed. To not only be a self plane shield, but so
that it could also be used as a chaff deterrent for a nearby ally aircraft.
The chaff is wound in a cord around a center cylinder, like a craft store yarn cone.
It can be launched as an air to air missile.
As it travels it unwinds and spirals out, releasing chaff in a wide round disc of coverage. Ala, spiral in the sky.
It provides hundreds of times more barrier coverage, than conventional chaff releases.
You have the option of shielding another friendly plane, by launching the missile between the friendly craft, and the enemy warhead.
This may or may not be the explanation for this video, but it may be a possibility.
