Costa Rican UFO

Malvin Badilla, a Costa Rican construction worker, has apparently recorded video of a small, hovering, disc-shaped object with his cell phone camera. After watching the local news report below, I don't really have a theory as to what the thing actually is. The video is pretty low-res, and there isn't much in the way of reference points. Badilla says it was about the size of a tractor tire. While it's possible the thing is a craft full of adorably tiny extraterrestrials, I'm thinking it's probably something spinning on a string.
