I would guess that one logical course of action was to reduce speed in order to reduce air pressure on the windscreen. Perhaps the reduction in altitude was also to protect the pilots in case the screen did break properly, so that they would not have to operate in low-oxygen conditions in the cockpit. Then again the speed would still have been far too high to be able to see anything in the cockpit, unless they had some serious helmets at hand (Think of driving a convertible at 150+mph without a windscreen). Anyway, enough armchair-philosophying from me, I am not an aircraft engineer and am just genuinely curious about the correct course of action to take in such an event.
I don't believe it's the air pressure from the outside on the windscreen but rather the pressurization. The plane is like a pop can with pressure in the plane cabin relative to the outside. The risk is the windshield blowing out (opening the pop can) vs being pushed in.
