I've got a friend who was an SR-71 pilot, and he said "no" on the VHF radio.
As for supersonic flight, during the mid-90s, when they tried to bring the Sled back, he says they had 8 canned routes they could fly that didn't generate new noise complaints. They rotated them, based on weather, and to minimize the impact of their "boom". He said the mission planners used a 75nm turn radius template to wind around the areas that they were required to avoid (large cities, mainly).
Must have the same type of airspace around here. At least twice a week, you can hear a sonic boom or two here in SE Tennessee. It comes in waves. One week it could be everyday and even twice a day on a few occasions. I did some research and it showed that there is a corridor that runs through here where they test the F-22 out of Marietta after it gets off the assembly line. At least thats what the 2 our 3 pretty reliable sources on the net said. After the boom, you can look up and see 2 contrails and sometimes looks like they are maneuvering around. Pretty neat to see, but sure does scare the s*** out of you!
