Object not bullet
The NTSB’s lead investigator says the object that hit the train windscreen is not a bullet, and cautioned that there is still not enough information to determine whether it was related to the train derailment.
I’d like to downplay that part. I’ve now seen the fracture pattern. It looks like something about the size of a grapefruit, if you will. And it did not even penetrate the entire windshield…It could be completely coincidental or it could be causal. And that’s exactly what we intend to find out.
