Good question Union! I've been thinkng the same thing myself- surely there must be a glass product available today that is srong enough for hatches and ports. I recall seeing a vídeo some time ago about a Florida inventor that came up with a special glass that could withstand hurricane-driven debris hitting windows. I wonder if it ever went to market? FWIW, my hard dodger windscreen panels are made of tempered glass. They're as new and clear as the day they were put in.

CCRiders, I think that's the vídeo I saw- they shot a 2x4 out of a canon and the glass deformed and crazed, but remained intact. You woudn't happen to know the comercial (market) name of this glass, would you?
