Doh!! Looks like the roof took a hell of a beating too. :shock:
Nearly happened to me a couple of years back. Doing c60-70mph & bonnet started "flapping". I'd forgotten to close it after removing the quick release plug that's fitted to it for the trickle charger and it was only staying down due to the release lever. Close call I'll say, sorry you weren't so lucky.
My daughter wasn't so lucky last year herself - new windscreen please :lol:
