I've never seen it happen before. There is some pressure on the edges to create a seal and prevent leaks. Not saying the antenna caused it, but it didn't help. Like I said I've never seen a car come in with that before.
It take's ALOT of force to break that glass, something had to have hit it. You can bounce a hammer off car glass. Anyone ever try to break a car window with a hammer?
