Lived in central Washington State. We would hear sonic booms all the time. SR71s out of Cali would linkup with a tanker over the north Cascades. Once refueled they would head out on their mission. Given their range and altitude I would imagine it didn’t take long for the Blackbird to reach and exceed 30,000 ft. Kinda made sense because Fairchild AFB in Spokane has KC135s based there. A specially outfitted KC135 would be used to do the refueling.
