Jumbos are mostly the same size, except for the SP version which had a shorter fuselage. The main visible modification to some of the later versions was extending the upper deck... And the winglets. |

Hey, yeah it is. Except instead of a web page it is the original book scanned. Well what do you know... |

The link is from the NASA history site. www.hq.nasa.gov/office/pao/History/Think I ferreted it out a good while ago? Never seem to get the time to read it properly. I prefer books for that, it went for another tome I had heard about, "Chariots for Apollo" www.hq.nasa.gov/office/pao/History/SP-4205/cover.htmlBook appeared to be out of print but there it was on line. |

I've been using the Orbiter spaceflight simulator to see if it was possible to launch towards to moon on the 16th of August 1976.
It turns out that there is a launch window opening up around 22:20 on the 16th of August 1976 (Universal Time) eg the 17th of August (PST).
However it appears to push available fuel to the limits (at least on the S-IVb).
When/if I reach the moon I'll be able to see just how visible the landing site was.

Tha's some interesting software if it has the Earth rotating east-to-west.   ;D 22:20 16 Aug 76 UT is 15:20 16 Aug 76 PDT. California is on Daylight Savings Time in August. The time would be 14:20 if it was PST. |

The above launch time may or may be viable, I have not been able to get the Earth-Moon flight time below 128hrs which is about 5 days to the moon on a mission length of no more than 12-14 days.
Still have not reached the Moon yet.
Even in a computer sim with time compression these things take time.

Thought I'd just post an update on my attempts to simulate the mission. Somewhere I got something wrong and ended up doing a flypast of the lunar surface.  It's back to the drawing board for this would be lunar explorer. Interestingly enough using the Orbiter flight simulator to run a mission based on NASA's own simulation results (In this case for an Apollo 11 mission targeted for Sinus Medii.) everything went remarkably smoothly. If anyone can point me to a listing of lunar launch opportunities for 1976 I would be very happy. |

Someone on Youtube has put together a synopsis of the 'Apollo 20' footage here. There is some in-flight footage that I'd like someone to confirm. There is interstage separation between an S-Ic & SII that looks nothing like the Apollo 6 footage. Any idea which mission it came from? Also amongst the comments is the following: Anyone heard of this guy? |

There is interstage separation between an S-Ic & SII that looks nothing like the Apollo 6 footage. Any idea which mission it came from? I'm fairly sure it's computer generated. Three points. 1: There was usually a 30 second delay between dropping the S-IC and dropping the interstage, whereas here the delay is much shorter. 2: This footage was only required during the testing of the Saturn V, and to my knowledge wasn't done for any of the manned Saturn V missions. 3: I don't think the Earth moves at all in the footage supposedly recorded from the underside of the S-II. Also, there's something about the quality of the footage that looks more like CGI footage than film. Not me. But that means nothing. ;-) |

Any idea which mission it came from? I agree that it looks like CGI. Furthermore, the size of the Earth is all out of proportion. Stagging occured at an altitude of about 100 miles, yet we can see the whole disc of the Earth. Definitely fake. |

And not even a very good fake.

And not even a very good fake. Shortly after the first 'staging' footage is a scene that purports to have been taken from inside the interstage between the S-Ic & S-II, NASA never placed cameras in that location. |

While it has been a long time since anyone posted to this thread I thought I'd bring it back to life. It seems there are still people out there pushing the Apollo '20' wheelbarrow. One such is Moonwalker1966delta who has posted the following on youtube (All spellings as on the website). 1. Apollo 19 incident. ( www.youtube.com/watch?v=MQMTbsePb7Q2. Apollo 20 EVA1. ( www.youtube.com/watch?v=a-A8RmnWaG0) According to this video the 'tyros' satellite was used for the relay of signals from the Lunar farside 3. APOLLO20 EVA2 ON THE WAY TO THE MOTHERSIP. ( www.youtube.com/watch?v=d0treeb38C8) I'll be trying to download these from youtube for study purposes. |
