Does the US Air Force operate supersonic fighter jets over land?
I heard that the FAA banned supersonic flight over America due to the shockwaves creating loud booms and breaking windows on the ground, therefore the Concorde only operated over the Atlantic Ocean.
However, is the US Air Force allowed to operate supersonically over land? How about in training missions, or drills, or a real event? Did they go supersonic during 9/11?
