Exploding UFO or is this a Chem-Bomb dropped near San Diego -Jan 18. 2014

Videographer ccrow777 has no idea what to think about the strange phenomenon he filmed over San Diego last night.

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.
