I flew the "3" had several strikes with it too, so I am quite familiar with how it is built. You missed the point of my post since they didn't reduce the speed from 145 kts to 130 kts as a result of that particular incident did they? The point is that the regulation has nothing to do with bird strike protection but rather traffic management, what has to do with bird strikes is the several layers of glass and plastic which aircraft windshields are built today and all large transport aircraft's are certified to withstand a large bird impact at high speeds. the assumption of the original poster is incorrect
