Have you ever been out for a walk, minding your own business on a nice day, only to have something mysterious fall from the sky and land right by you?
No joke, I was once leaving the supermarket and heading to my car, only for a Lego brick to fall out of the sky and land right by my feet. I suspect a bird had been carrying it in their beak or something, but the point stands that it's a pretty surreal experience.
Whether as a result of animals, ridiculous weather, or possibly even a plane crash, there have been plenty of strange incidents of things falling from the sky. The incidents of balloons coming down are an obviously man-made error, while things like fish and insects raining down have often been attributed to crazy weather conditions.
Some incidents though are ones that defy all explanation and just leave everybody involved puzzled. Case and point: a batch of frozen, grocery store pork recently fell from the skies above Florida, and people are stumped as to why.
