I watched it from a small plane about 10 miles west of the Cape. Me and about 500 others! That count came from ATC controllers later that day. They quit counting targets in a 10 square mile area. Talk about dodge ball with planes....to make it worse, the Air Force sent a flight of 4 F-4's up through the mess about 1 minute pre launch! We had a radio with the count down going and everyone timed a turn so we were all pointing at the pad as it went off. Got an old picture of it here somewhere....all you can see is a small pinpoint of light as the candle burned oh so bright! Will never forget the day I saw history made.
