I guess I understand why they locked the building down but I think it is a mistake. Usually you don't want that picture of what is a fairly normal sort of engineering snafu (this would hardly be a story except for the MAX) out there with scary headlines, but one of the big problems with the whole MAX debacle was the lack of transparency and circle the wagons approach to the disaster by Boeing. If they let the press in to sniff around and made engineers available, I think it would go a long way to reinforcing the "Boeing comeback" narrative that we need to start seeing pretty soon. "This highlights our commitment to building the safest planes ever", "the engineers are back in charge", "we won't release it until it is right" sorts of
PR taglines practically write themselves.
What are they worried about, the stock is going to take a short term hit?
