There should be small pieces of whatever they hit embedded in the body & glass of the aircraft. As long as they are analyzed, the cause of this won't remain a mystery forever.

Unless it was hail.

My first thought was that this is more likely to be a spontaneous failure of the windshield glass under pressure, due to manufacturing flaw or improper maintenance. Things like that have certainly happened before. But then again, it seems weird that glass fragments would be projected inward in that scenario.

There are pictures of the outside where you can clearly see impact damage to the top of the window frame.

At speed, I don't know what the outside pressure on the windshield would be, but I'd be surprised if it was lower than the cabin air pressure.

After all, it is called a wind "shield".

Don't worry, if it can be blamed on Boeing, it will be.
