How fast is that helicopter moving at top speed? I&#x27;m genuinely curious the amount of energy involved in a collision like that and if it would be enough to break the windshield. I presume the windshield (possibly incorrectly) on a helicopter like that is Plexiglass or some other plastic to save on weight. How do they handle impact?  I have to imagine birds as big as geese get hit regularly. How do they handle that kind of impact?
