This is clearly off-topic, so please feel free to ignore:

I disagree with the sonic barrier wall analaogy. Is it that clearly
technical barrier the slowed down jet research, or did the nuisance of
sonic booms to people on the ground just make supersonic R&D less
convenient? I've heard that supersonic travel over land is restricted in
the US.
