The site is clearly a labor of love by
Ben Feist and all his collaborators. There's an instructions/credits button on the
Apollo 11 in Real Time page with details.
The synchronization of all the audio (and there's a tremendous amount), video, photos, and text make watching the replay as fascinating (if not more so) as the original broadcast. It's one of the best examples of multimedia that I've ever seen.
(I had the scale model of the Saturn VI -- as tall as I was. And of course the starship Enterprise, and the Klingon battle cruiser. For anyone from that era in need of a memory refresh, I recommend Richard Linklater's "Apollo 10 1/2" for a fun trip down memory lane)
