It does not take any great skills at critical thinking and problem solving to realize what is going on. People know they are being handled. You should be ashamed of yourselves. You must not realize that people know. It is your reputation, your analytical skills, and your honesty that is on the line here.
Integrity still matters.
Honoring the trust of the Nation still matters. I am not too worried about the lies that will be told at the August NTSB closure meeting. The truth is beyond time limits. This matter will not be closed however much you want it to be. The truth will remain the same no matter how much time passes.
