This sometimes happens to the pressurized Beech turboprops. Usually the windshield develops a crack, sometimes herringbone pattern cracks, and sometimes it appears like "crazing" and pretty well obscures the view. There are specific limits for ferrying the airplane -- pressurization differential, etc., and advice is available from Beech, Raytheon, Hawker Beechcraft (or whatever they're calling themselves this week). Sometimes limits are even published in the MEL, with specific limitations. Usually damage must be confined to the inner or outer pane of the windshield. They're glass, incidentally, except in rare cases where the airplane is not approved for flight in icing.
