Images above: Sprites over thunderstorms in Kansas on August 10, 2000, observed in the mesosphere, with an altitude of 50-90 kilometers as a response to powerful lightning discharges from tropospheric thunderstorms. The true color of sprites is pink-red.

Or maybe Sprites are aliens and the natural cause explanation is just a cover...

Lymon powered sprites?

A natural phenomenon called silliness explains most UFO sightings. :)

Pretty cool. I've come close to being hit by lightning a few times while photographing thunder storms. No one ever said I have common sense.

Maybe it's the 'vodka'...

While cool, they only last for a second....it is frankly.....stupid to consider they could be UFO sightings, at least the ones that last for awhile.

The phenomenon has existed for millions of years, but was first discovered and documented in 1989.

BUT, BUT, BUT! UFO's are real, just like the easter bunny & santa claus! Strawberry Quik told me so and demanded I agree with him! He even tried to claim my father didn't love me because i tend to rely on facts (like my daddy taught me), not fallacy to make decisions.

UFOs are a natural phenomenon? No way. That is too complicated an answer.

The simpiler, more straight-forward answer is they are alien space ships from a planet over 1,000 light years away that planted live on Earth thousands of years ago and have come back to monitor our progress. When we become enlightened enough they will teach us the secrets of intersetlar space travel so we too may take our place in the community of planets.

Now isn’t that a simpiler explination?

This explains why UFOs sometimes hover in trees and have occupants, and, hey wait, no it doesn’t... ;’)

Or maybe

Thanks.
