Yes, all Boeing heavy jet transports have blowout panels in the floor and other places to accomodate the largish airflows associated with rapid decompression. As I recall, just about everything has a blowout panel, lavs, flight deck, cargo holds... The ones in the floor are next to the sidewalls, right over the crease beams (called a "coat hanger" by the assembly mechanics, FWIW). -- Terry firstname.lastname@example.org "Anyone who thinks they can hold the company responsible for what I say has more lawyers than sense."
