We did have flight operations in that region today that included supersonic testing. Our pilots work to perform these flights in a manner that hopefully impacts the fewest number of people while still allowing us to make sure each aircraft made meets our customer requirements.  Atmospheric conditions sometime make a difference in whether the sonic booms reach the ground.  It is our intent to disturb the community as infrequently as possible.
