What is this that exploded near San Diego?
Ccrow777: "I filmed this while filming chem planes spraying very low and the object appeared after the second, higher, trail was laid. Whatever fell from the object rained down into a very urban area full of houses."
He wonders whether it is a chem-bomb being dropped near San Diego or a UFO targeted by some kind of electro-magnetic weapon.
As you can see from the footage the object does explode releasing some sort of liquid.
