Can anyone logically explain my UFO sighting?

Still trying to figure out mine

In the night sky

Looked like a satellite moving across the night sky

But the movement was not straight or steady

It was moving ahead but in a twisty, turning path

It was not steady either. It stopped, slowed down, accelerated ...

The U stands for "unidentified."

However, I know exactly what your sighting was. The earliest time travelers were magicians. Their first attempts came with loud booms on arrival from the time-compressed sound waves. The "sonic boom" disinformation plan was successful in covering this up. On their way to perfecting the process, some failures occurred. One of which was a ceremony that involved heating up assorted mystical components (2000 deep fried bird-anus rings for instance) in an enormous silver cauldron. The traveler would don his ice-breeches and leap into the blazing cauldron at just the right moment to "ride" it to a fantastic future. The poor bastards would skip through the time stream, appearing for 15 minutes at a time to shine in the sky on their unending, stuttering journey to the end of creation. Their appearance of movement is only due to the rotation of the Earth vs the start of the journey. Did you hear the howling of agony from it?

Bad Weed.

It was probably a high altitude research balloon. These balloons are sometimes mistaken for UFOs.
