The F15 is meant to resist penetration of objcts at up to Mach 2!

For goodness sake, that's twice in a week I find myself agreeing with wnut.
Even basic car windscreen are safety devices (amongst other things), otherwise they wouldn't be expensive laminated objects. Why else do you need to carry around a hardended pointed hammer to break them if you fall in to a river (Well, I do - lots of long roads next to rivers where I live)
And yes, an F16 screen can withstand impacts at mach 2 - so not really comparable to f1's rather palty 200mph.
And to be honest, they don't need to withstand penetration as such, just need to deflect enough energy go give better protection that a visor alone.
