The outcomes were SUBSTANTIALLY worse than the US government expected. The results of this study are why even war planes rarely go supersonic over the continental US.
I remember the sonic boom over the Seattle area in the summer of 2010 when Obama was in town. A seaplane accidentally violated the 10 mile exclusion zone around Air Force 1 at Boeing Field and two F-15s were scrambled from Portland International Airport (Oregon National Guard operates the fighters tasked with protection from Northern California to the Canadian border). It was quite exciting.
