We had two separate sonic booms yesterday morning so somebody must have been in a hurry. At first I thought they were quarry blasts, but the local airport knew what it really was as it shook their hangar, and they are way too far away to have heard anything from my local quarry.
I heard them boom back in the 60's but not too often after that.
