The NTSB asked Boeing for the names of the specific people on the team that replaced that door, and they said Boeing hasn't provided that. In Boeing's response, they didn't say they provided that, either. They said they provided "names of Boeing employees, including door specialists, who we believed would have relevant information." If they had actually provided the names of the crew that did the work, they'd have said they did exactly that rather than giving a lawyerish sidestep. I don't even think that the people who'd have done the actual repairs were even Boeing employees. Isn't a big part of the criticism that this work is farmed out? Not positive, though: that could have been work for one of the other recent Boeing catastrophes.
