thanks for the ball lightning followup Karl 12 -- I know I gave it as the explanation for a couple UFO sighting links you wanted me to check out.
Apparently ball lighting follows other electromagnetic signatures -- which explains it appearing inside commerical jets....

While I do believe ball lightning could explain a lot of UFO sightings readily, I would really need the data on how it formed (observed data, not theoretical) and how frequently it formed to really make any conclusions. I can also say without a doubt the one UFO I saw long ago was not ball lightning, as it was basically a hunk of polished metal hovering in broad daylight .

I've been thinking about this, there's a similarity with the orb UFO's and ball lightning. There's not much evidence of ball lightning, maybe one photo and stories, but people still believe in them but not in alien UFO's
the question of whether this incident might be explained in terms of any "plasma effect" is considered but rejected. In the end, this case is conceded to be unexplained.

I'm looking for any mention of plasma balls or plasma lightning in the two new links you gave. I could find NONE.
The Committee has made a careful examination of the present state of the UFO issue and has concluded that the controversy cannot be resolved without further study in a quantitative scientific manner and that it deserves the attention of the engineering and scientific community..

"There's certainly no consensus. I don't think that anyone knows what it is," said Graham K. Hubler, a physicist at the U.S. Naval Research Laboratory in Washington, D.C...
While some skeptics remain, there is significant observational evidence for ball lightning's existence.
"There are around 10,000 written accounts of observations covering many countries with similar properties recurring in many observations," said John Abrahamson, a professor of chemistry at the University of Canterbury in Christchurch, New Zealand.
"All this points to a phenomenon which is repeatable and justifies a single label."
Thousands of eyewitnesses have described seeing a floating, glowing ball similar to a tennis ball or even a beach ball..
Ball Lightning Research
Despite some fairly consistent characteristics, ball lightning has thus far defied scientific explanation—but it's not for a lack of theories.
Scientists have postulated that plasma may be behind the phenomenon.
Plasma clouds are composed of charged particles that recombine into atoms and glow with light.
The clouds may be created by an energy source like a conventional lightning bolt and could theoretically form ball lightning.
An alternative theory promotes the notion that small particles held together in a ball by electrical charges emit chemical energy through oxidation.
This theory suggests that when lightning strikes a surface, a vapor is formed. The vapor condenses into particles that mix with oxygen in the air and then slowly burn with the release of chemical energy.
"The whole picture is electrical energy, in a huge amount really, and a small part of that energy gets converted to chemical energy and stored in particles," said the University of Canterbury's Abrahamson, who supports the theory.
Laboratory work is currently seeking to reproduce ball lightning under this model and several others.
Meanwhile, the Naval Research Lab's Hubler hopes that technology will leave less room for the real thing to hide.
"There is such a proliferation of video cameras these days that people must have captured [pictures of] ball lightning, and it would be an immense help to see some of those videos and study them," he said.
"Here's a real, physical phenomenon that's out there in nature, and we don't have the foggiest idea what it is—that's interesting," he added.
"I hope in my lifetime we find out what it is. It's possible that there's some very new physics in it and that could be very profound."

Does Ball lightning account for some UFO sightings?

It does seem to show a darker part along the bottom, so maybe he didn't rotate the camera. Could it still possibly be something he threw in the powerlines that then violently 'sparked' to the left by sheer electro/magnetic power?
I have no clue, but here's the sequence as in the original video:

Ball Lightning report:
[atsimg]http://files.abovetopsecret.com/images/member/085d956bc166.jpg[/atsimg]
Between two flashes of lightning perhaps five minutes apart, I happened to gaze out the window to view the downpour. At that moment a fiery ball of brilliant yellow moved across our front yard about 10 feet from the ground. The ball itself was somewhere between the size of a grapefruit and a soccer ball. I saw its tight spherical shape engulfed in a sort of plasma while a tapered tail of bright yellow flame trailed behind it for a distance of about twenty-five feet.
It moved not so quickly as a bird might fly across the yard. It did not "streak" but simply moved deliberately at a sort of cruising speed. My companions saw it only indirectly but I eyed it thoroughly, completely, and totally.
As I tried to come to terms with what I had just seen, I mentioned ball lightning - a rare and mysterious phenomenon I had read about some time ago. But my recollection was that ball lightning is so rarely seen that its very existence is in doubt.

Arbitrageur, good call -those are some very interesting pics.
There's another strange account below from 2007 which was said to happen between two flashes of lightning:
