[PSUBS-MAILIST] Crash bars / space frame

[Sean T. Stevenson via Personal_Submersibles]

This may be most appropriately directed at Vance, Phil et. al., but for anyone who incorporated into their designs impact protection for either your windows, hull or vulnerable external appendages in the form of crash bars or space frame, I am curious as to what scenarios were considered or what impact forces you designed to protect against?
