TOWN 'N COUNTRY - Late Monday, Andres Javage's Ford Mustang was still sitting exactly where it was Sunday when it was crushed by a giant block of ice from the sky.The ice was gone, but the damage wasn't."I didn't think it was that big of a deal," Javage offered, back on the job as a mechanic.He may wonder about the attention his car's been getting, but everyone else wants to know how something like this could happen.Most experts believe the huge ice chunks fall off airplanes, but that's not the only theory."Oh, the paranormal! I don't know about ice chunks falling off of UFOs, but it might be global warming. Everything else is, so why shouldn't this," FOX 13 meteorologist Howard Shapiro offered. "Just kidding!"Shapiro was referring to the belief by some scientists that such ice balls, or megacryometeors, are caused by changing conditions in the lowest level of the atmosphere. But he says the simplest explanation is the most likely."Logically, it has to be an airplane. There's no other mechanism up there to form something that large. Hailstones don't exist that large," he continued. When the accident happened, police say, no planes were in the area. But now federal investigators are checking their radar and say it's "outside the norm" for a big chunk of ice to fall from a plane and cause damage like this."If they analyze it and don't find any waste in it or anything, then it didn't come from the bathrooms. But if you have a constant leak, lets say of freshwater, that's coming out and freezing it would make logical sense that you're getting this onion-skin look to these big stones similar to a hailstone," Shapiro added.Andres Javage doesn't really care why. He just wants a new car, and maybe a chance to cash in on the fact that what happened to him is one in a million."I thought it was pretty good luck. I was going to play the lottery tonight," he added.This isn't the first time falling ice has caused major damage. In fact, it happened twice in the last two weeks at homes in Philadelphia and San Diego. Fortunately, no one was injured during any of these incidents
