we will talk to kevin stirling, director and producer of "mooned beach," a documentary that looks at the apollo 11 -- "moon beat," a documentary that looks at the apollo 11 landing. >> when i heard the alarms, when they were descending, i felt sure that the mission was going wrong. i could not believe that they would be able to make the landing on the first landing mission. the lunar module, this weird spider thing, was such an unpromising a vehicle. i was sure it would tip over when they landed. i was expecting that mission to be aborted, and if it was not aborted, i felt the odds are that it would not get back. >> we are now in the approach phase. everything looking good. all two, 4200. you are a go for landing. -- all to 2, 4200. you are a go for landing. all two, 1600. 1400 feet, still looking good. 1201 alarm. >> the touch and go of that, when you think of it, as they were coming down and there were ready to abort, to get a wonderful guy in the control center who kept on coming back to jean and saying, "is ok." alarms were coming on and everything else but he kept on coming back
