ttb, please tell me, as I am a mere mortal, how more regulation would prevent an aircraft operating in controlled class D airspace, cleared for departure routing and frequency change to controlled class B airspace from having an emergency causing it to bust into airspace it was not cleared for in the same small piece of sky another aviator was unlucky enough to be operating in at the same time?
One would think "Aviate, Navigate, Communicate" would have been all the regulation required, and arguably the most effective in this situation.
The US has a pretty mature approach to Self Regulation, that works pretty effectively across various types of legislation... Every so know and then people/organizations need to be reminded of their self regulation obligations yes, it does not mean the right to self regulate, when it works for 99.9% of the time is at fault.
