    The BBC has produced a podcast series on Apollo 11 13 Minutes To The Moon, which I recommend. Of particular note to hams is episode 11 where they play the comms during descent to the moon real time including interference. The whole story is still quite moving even fifty years later.

    It was an impossible feat performed in an unstable time. Incredible.

    Whose real time? Because of the distance involved and the time required for radio signals to traverse that distance, the timing of the conversation would have sounded noticeably different on board the spacecraft versus on Earth.

    Here's a site where the audio has been reconstructed to show the timing from a lunar perspective:

    Incredible, yes.

    But it should be remembered that NASA essentially had a blank check for the Apollo program, and anything that supported it. Plus the best German rocket engineers Operation Paperclip could snag. And an aerospace industry that was going full blast but also looking for more.

    The podcast clearly indicates it was the Capcom loop.

    Incredible, yes, but clearly not impossible. ;)

    Too bad none of us will live to see a successful manned mission to Mars

    I have been enjoying 13 Minutes to the Moon. FAcinating look at what al went into maing the final decent and landing possible.

    Something that is also interesting is the website: https://apolloinrealtime.org/11/
    This site combines a number of audio feeds from both Apollo and mission control, video, and still pictures andput it all together to "watch" the whole mission in real time, or something pretty close to it.
