I've never thought lenticular clouds were a good explanation for UFOs. I've seen a lot of them and there's no way to mistake them for anything else. First, they're way too big--even the smallest ones are miles across. Second, they have no noticeable motion. They're a visible manifestation of standing waves in truly huge air currents. These air currents can't change direction fast enough to make the cloud move fast enough to see happening. Nor do these things suddenly vanish.
So while from certain angles and under certain lighting conditions they look like flying saucers, it's always obvious that they're clouds. They're just clouds that look like flying saucers, as other clouds look like people, animals, or other terrestrial objects.
I guess ball lightning is a good name for these blobs of light I was talking about, because they seem to be electrostatic things. Problem is, what I was talking about happens when there are no storms around. That's why some folks think they might have to do with tectonic activity, and call them
earthquake lights, even if the earthquake involved is too small for people to notice, at least in the areas I'm familiar with (west Texas and SE Missouri). But whatever causes them, they seem definitely to be the result of some natural, non-paranormal process that we just don't understand yet.
I've seen actual ball lightning twice. Once it came out of a telephone handset, and the other time out of a radio handset. Both times, there was a bad thunderstorm going on and lightning had just struck close by. Both times, the ball was about 4 inches wide and shimmered between violet and electric blue, while appearing to be rotating VERY fast. Both balls skipped and hopped along the ground in an irregular path, crackling and spitting, for a second or 2, then disappeared, without damaging anything. They didn't last long enough for me to jump out of their way, so fortunately they didn't come right at me

. They left that ozone smell behind them.
