I have no doubt that some UFO sightings could have been ball lightning. Of course there was a long time when scientists didn't believe in ball lightning. Or at least that is what I have heard. The report may of course have been what a few scientists said, not what the general consensus would have been. Taking the words of a few and attaching them to the many is a common thing to happen.

But as far as I know there still isn't much of a consensus as to how ball lightning and St. Elmo's fire work. I presume it is some kind of a plasma display, but how it manages to stay together is a pretty good question.
