Eric, this was exactly my thinking when I took out the drain plugs.  Maybe water would cause some missing but it should eventually clear.  I have to admit that I didn't think about freezing (who would when its always 80 and sunny :-), or LARGE quantities of water, or other contamination besides water, or that gulp of water I might suck in when the tail comes up (which probably is not a factor because the drain plug is not as far aft as the fuel pick-up tube).

I think I will still do the experiment, but maybe the drain plugs are going back in reguardless of the result.
