Who do you think the NTSB are? The NTSB is staffed with people familiar with the industry - it has to be. Thus, a significant portion of these people are former Boeing employees. And historically, many NTSB staff have gone to work for Boeing (and other industry giants) after their stint at the NTSB as well. It's not that large of an industry after all. This is known as the Revolving Door.
