At about 0230, 5 April 2024, Saint Peters/Harvester MO, I was returning home from a quick run to the gas station for cigarettes when a single bright light appeared in my line of sight in the sky, travelling at a high rate of speed slower than a shooting star but seemingly faster than a plane, moving close to parallel to the horizon before turning downwards (or flying away in same direction, hard to tell exactly) towards the horizon before I lost it behind trees and such. If it wasn't a plane crash I'd have to say maybe a UFO, definitely not what is described as Elon Musk's space station thing as it was a single light.
