> Some of you may have noticed the nuclear missile video says the explosion took place 10,000 feet above our group of soldiers. Apparently, the video is wrong. The Natural Resources Defense Council checked the numbers and says the explosion, part of Operation PLUMBBOB, was actually at 18,500 feet.

Well, there's actually some pretty good proof here that the explosion was closer than that: I count the time between light and sound to be slightly less than 13 seconds (and voices sound right so I'm assuming the recording is accurate in that respect). That would mean the explosion is about 14 000 feet away from the camera.
