Cabin floor, I remembered but wasn't sure.
So what was Sam S pointing to on the 777? Only on the -x or also on the classic? (I mean 777 classic must have been the pinnacle of safety and reliability in the Boeing fleet, so I'd be surprised)
For the sake of Boeing (and millions of the traveling public) I hope you're right.
Fair enough.
