> Of course, FAA, aviation, space, healthcare etc. should have much lower tolerance to risk For space, FAA is primarily concerned with risks to public safety (launch vehicle goes off course and crashes into populated area); and also risk to third party space assets. It also cares about environmental risks, but to a lesser degree (risks of short-term environmental harms can be tolerated, especially if there is a plan being seriously pursued to mitigate them). Very different from FAA for commercial aviation where passenger safety is paramount (or at least that’s what it is supposed to be.) From what I understand, FAA considers all human spaceflight to be experimental, and passengers/crew need to sign a waiver acknowledging there is a significant risk of dying-nobody is asked to sign such a waiver before boarding a commercial flight, which is why the FAA’s commercial aviation division has enormously tougher passenger safety standards than their space division.
