Yes, but I can't convince myself it was sound transmitted from the Cape. Sort of a low rumble that lasted for perhaps 10 seconds. But the calculation is possible to do. Sound moves at about 1125 feet per second. The cape is 90 miles or 475200 feet straight line distance from TV. So 475200 feet / 1125 ft/sec = 422 secs or 7 minutes. Now the reentry burn was at 7:13 secs so darn close to the right time.
