What may be of great concern are the allegations of "schedule before quality" but it takes just one more battery fire or one hull breakup to ruin the 787 project for the foreseeable future.
And there you have it : schedule before quality.
Through the test of time it either flies for two decades and saves numerous operators from drowning in red ink along with safely delivering the payload - or it turns out to be a bridge too far.
Drug testing isn't relevant , neither are bullets fired into batteries. In my backyard I can fire bullets into cans of petrol and the result is very unsafe. But all aircraft have fuel tanks. The problem depicted by this documentary is that of shifting standards of safety and actively overriding the safety inspector's concerns. The motive for doing so ( irredeemably behind a reasonable service date schedule) is well documented.
