Just a useless story... but the Galaxy has huge doors. The visor is probably 80-90 linear feet. And we only occaisionally have trouble latching them. The problem is not fuselage flexing, so much as, all the electric targets that indicate closed. It's sort of like the old Christmas tree lights where any one bulb out took the whole string out. If there is a strong wind blowing, it requires some thought about which door to close first, front or back.
