The computer than became over loaded because it had to do too many calculations per second. It for it had to re-account for a new trajectory, a new landing velocity, a new target spot, chaining fuel levels etc. .. everything was dynamic all at once! The computers warning lights then came on all the while Buzz was calling out the fuel level. Neil then switched off the flight computer and flew the Eagle manually in which he landed on 17-25 seconds left of fuel. The funny thing is your reference that you provided says a simplified version of what I just said ... it is funny that you dont understand your own reference!
Im sure you read popular mechanics ...
http://www.popularmechanics.com/scie...n-mars/4318170


As you can see you are wrong and have no idea what you are talking about then have the nerve to tell me im wrong lol! This is going to be my problem when going to industry ... arguing with non engineers lol! You guys think you know something because you think your logic to be intuitive and or you know some basic facts about something but in reality the real world can be counter-intuitive on a regular basis. Then when we explain to you and talk to you like an engineer you do not understand and or miss-understand what we wrote. To make matters worse when we talk to you on a simple non technical basis you feel we are over simplifying it for you and ask for more technical details. Overall I just cant stand talking to non engineers about engineering problems and I hope I never have to do it in the work place
Since you made an effort to address a specific point and added “documentation”, I will try to help you a little. First, you should preferably get your documentation from official sources with some context because you don’t seem to be able to analyse the information properly on your own. I quoted Margaret H. Hamilton, Director of Apollo Flight Computer Programming MIT Draper Laboratory, Cambridge, Massachusetts and you show up with a “knuckle-biting” story from Popular Mechanics. Are you even serious? Is your young brother or maybe a senile uncle using your computer while you are busy getting your 15000$ a year education?

You are a person who would rather be right at all cost, than admit to be a little ignorant about certain issues. You are also doing a disservice to the very NASA personal and NASA program that you are claiming to admire, while condemning others for not caring enough. You can try to fool people on AAm, but you are not fooling me. You actually have no clue what you are talking about. The guidance computer functioned extremely well and that was crucial to the alleged successful Apollo 11 landing. This is clearly stated by our friend, Margaret, and you should go read it again in my last message.

A computer generating an error message does not mean that it failed. In this case, it was the Rendezvous Radar Switch that shouldn’t have been left on ‘AUTO’ and so it provided too many useless instructions (it was not after Neil’s intervention as you seem to think so). This overloaded the program which then generated the error codes to alert the crew that it was dropping some lower priority tasks. The program was designed to do just that. Basically, you can question the logics behind programming such a procedure, but that is not a failure of the program itself. The computer was just doing its job flawlessly. It was not immediately clear what those messages were, but after a while, it was deemed by mission control to not be a cause for major concerned. It is only after this that the landing target was determined to be unsatisfactory and that Neil took over some of the tasks to land in a location that he considered was safer. Here, there are a dozen accounts and retelling of what actually happened, but the thing that is clear is that Neil never landed in a complete manual mode (although he might have switched to that mode for a while, but it is unlikely) as he took over some tasks while the computer was still performing the others. Again, Neil decided to override some of the computer’s tasks, it does not mean that the computer failed catastrophically as you seem to think. The point is that the computer was still needed for landing as you don't seem to understand. Do you actually comprehend the tasks that were needed to be processed? If you go to the proper sources, you will get all the confirmations of everything I wrote, which refutes your inane out of order and undocumented description.

Here is Buzz teaching you a few very basic things about computers (listen to the last 30s, that is the important part for your understanding):
http://www.history.com/videos/buzz-a...ters-on-apollo

Here, Buzz fails to even mention your catastrophic computer failure part of your Hollywood script:
http://www.history.com/videos/diffic...ng-on-the-moon

Here is more information about the reason the error codes were generated. You might want to read a little (and watch less movies), since you were not aware about the fact that it was caused by the Rendezvous Radar Switch and not by Neil's take over of some of the tasks. There is also the part about why it is not a computer failure, as you wrongly believe, even after being corrected:

I remember bumping into one of our M.I.T. engineers, George Silver, who was usually at our office at Cape Kennedy. George had been involved in and witnessed many pre-flight tests. I asked him in frustration if he had ever seen the Apollo Guidance Computer run slowly and under what conditions. To my surprise and rather matter of fact, he said he had. He called it "cycle stealing" and he said it can occur when the I/O system keeps looking for data. He had seen it when the Rendezvous Radar Switch was on (in the AUTO position) and the computer was looking for radar data. He asked "the Switch isn't on, is it?" "Why would it be on for Descent, it's meant for Ascent?"

I rushed upstairs and suggested we look at the telemetry data. Some of the M.I.T engineers found the telemetry print out, found the correct 16-bit packed word, found the correct bit, and... yikes!!!, the bit was ON. Why was it on? It had to be set in that position by an astronaut. We looked at the 4 inch thick book of astronaut procedures and there it was -- they were supposed to put in on (in the AUTO position) prior to Descent. The computer had been looking for radar data. If the astronauts were trained this way, why had this effort never shown during training sessions? (I later found out that such training was for procedures only and the Switch was never connected to a real computer.)

But there was no time now for analyses or reflections. We called Houston and delivered the cause and solution. The final countdown to Ascent was proceeding. Just before ignition, and the last message sent to the astronauts, Glenn Lunney, the Flight Director, calmly told the astronauts to "please put the Rendezvous Radar Switch in the Manual position".

The Ascent and flight proceeded without incident.

Software Engineering Postscript

The Apollo program took some heat for this "software error" that almost caused Apollo 11 to abort. At M.I.T., we always thought and most would still maintain that the system operated as designed and saved the flight. We used a priority driven executive, rather than a round robin, FIFO, or table division executive. We provided for overload, or loss of computer speed, by continuing to execute the highest priority jobs. Those jobs (tasks) that fell off the queue were of lowest priority, perhaps a display refresh or some other non-essential procedure. Had we demanded computer time for every schedule task, then time would have run out, tasks would have overlapped, data would be confused and out of sync, and the flight would have been lost. Interestingly, this experience so influenced NASA's Jack Gorman and other NASA and Intermetrics software engineers, that we fought long and hard to retain a priority, asynchronous executive for Shuttle as manifested in the HAL/S language.
Now, you should go ask Buzz why that Rendezvous Radar Switch was left to AUTO. He has explained why and he knows that in the circumstances, it was a mistake. That is if this whole fairy tail of a moon landing actually did happen.

I suppose you will bury all this pertinent information in more “knuckle-biting” babble as soon as you can so that anyone still reading this (sure) will not be bothered to check your deficient logic, but I suppose this is the advantage you get when you post crap about Apollo missions on an Alizée forum.

Shows how much you know, Popular Mechanics is used often as a source on many engineering peer reviewed journals! Quit while you are behind you are making a fool of yourself! Also you saw who said the quotations I quoted ... so we can sit here all day long dick measuring on the internet but truth be told you don't know more than Neil, you don't know more than Buzz, you don't know more than Gene Kranz, and you sure as hell don't know more than me!
I am going to put those quotes up on this page too so everyone can see what a fool you are!
http://www.popularmechanics.com/scie...n-mars/4318170
Quote:
* Neil Armstrong, commander, Apollo 11: Prior to igniting the lunar module's descent engine to initiate the trajectory toward the lunar surface, I had been timing our angular rate over the craters on the surface below to calculate our altitude. I noted that, at ignition, we were somewhat west of our intended starting location. I inferred that our entire trajectory and landing point would be somewhat west of our planned landing spot.
Quote:
* Aldrin: We got the first 1202 alarm. So we look at each other, and we know it's in the guidance and navigation dictionary, but rather than try and get it out while the module is making a powered descent, Neil asked them what's the reading on the 1202 alarm. Then we got a 1201.
Quote:
* Charlie Duke, astronaut, capsule communicator (CAPCOM), White Team, Mission Control: I was shocked. Actually, "stunned" is a better word. I started reaching for my guidance and navigation checklist to see what a 1201 and a 1202 was. And, of course, Steve Bales knew immediately and didn't hesitate very long to say, "We're go on those alarms, Flight."
Quote:
* Kranz: Dick Koos, our simulation supervisor, gave us the 1201 and 1202 alarms. Steve [Bales] had never seen this before. During the simulation, they had an abort, which was his call.
Quote:
* Garman: Gene Kranz sat us all down and said, "I want you to figure out every possible alarm code that can happen in flight so that we're prepared." In those days, there was no such thing as desktop computers. So I wrote down all the alarm codes on a sheet of grid paper, with crib notes on what they meant and what our response should be. And I stuck it under the plexiglass of the console I was to sit at. And, lo and behold, one of them--well, a couple of them--popped up during the actual landing.
Quote:
* Eyles: What led to [the alarms] was an obscure mismatch deep in the electronics--two signals that should have been locked together in phase were only locked together in frequency. That hardware glitch involved the rendezvous radar, which really wasn't needed during the descent to the moon.
Quote:
* Ward: The computer was simply saying, "Hey, I've got more than I can handle, but I'm gonna do the important things, so don't worry about it."
Quote:
* Armstrong: The powered descent was the most challenging segment of the flight. The systems were heavily loaded, the margins were slim, and this would be the first time that the entire descent strategy would be fully tested. A decade earlier, while I was flying in the X-15 program, we learned, surprisingly, that all the pilots, while flying the X-15, had heart rates between 145 and 185. It reflected the mental intensity appropriate for a challenging situation. The Apollo data seemed to correlate well with our prior experience.
Quote:
* Carlton: I had a stopwatch. I'm looking at it, and at the same time I'm looking at the altitude, and I can see it's still a long way down. I didn't know it, but the guys were flying over a crater. We call up 30 seconds. I'm thinking there's no way we're going to make it.
Also watch this, maybe you can argue with these great men too and tell them how they are also wrong lol!

<iframe src="http://www.youtube.com/embed/rqQW-tmQRos" allowfullscreen="" frameborder="0" height="315" width="560"></iframe>

And don't be mad at the other members because I made a fool out of you (no you made a fool out of yourself) and now you are the laughing stock of anyone who reads this thread! You know im an Aerospace Engineer and very passionate about this field and I warned you i would make a fool out of you and now that I did you seem to be putting this forum down ... you feel like a big boy? Next time when someone tells you they are actually a near expert on a subject (and you knew I wasn't bullshitting) you should head the warning and not try to argue. By the way your last post is bullshit just like your others! Go watch Bart Sibrel, you seem to be just as smart and informed as him!

To quote Azhiri,
"I don't want this to get ugly - no more name-calling or insults to personal intelligence, that's silly and we're all bigger and better than that."

Come on, guys. Please refrain from the personal insults during your discussion. You are not making your arguments any more convincing by doing so.

Im sorry it is just so hard to talk to someone who is so blatantly wrong and who is even quoting correct sources and interpreting them wrong but yet somehow claims to know it all lol!

Edit:

I was looking for this ... in reference to my Japanese satellite and others from around the world claim from before!

Popular Mechanics is a joke:
“Popular Mechanics features regular sections on automotive, home, outdoors, science, and technology topics. A recurring column is "Jay Leno's Garage" featuring observations by the famed late-night talk show host and vehicle enthusiast.”

PM’s chief-editor is Jim Meigs, a notorious moron. PM is not peer-reviewed itself, so, basically, any clown can publish there. Go ahead and build your carrier to come on that sort of documentation if you want, I would advise not to.

So, ultimately, this is what this is all this is about, right? You and your heroes. Sure.

Mad at other members? I am having quite a good time in this thread, so far. I see no problem with other members. Just problems with your "knuckle-biting" Apollo stories.

You must love that piece of anthology, don't you:



Bart is a nutcase, but those highly trained NASA astronauts who can face any situation with calm and restrain seem a little out of control too:
http://vimeo.com/24508433



Seriously now, you should really stop a minute and reflect on what just happened in this thread. That would be beneficial to you.

Good luck with your career.

Not to worry lefty. I am done here. Sorry if this was a little more of a chore to monitor.

You clearly don't know a thing about the character traits of fighter pilots and test pilots! By the way I saw that video when it came out hence why I made reference to him before you even thought to post it .. you are not showing me anything I haven't seen (which is the general theme of this thread). But yea people love being called a liar to their face, being forced to an interview on false premise, and then having an obnoxious idiot like Bart talk to you explaining things to people who are a lot smarter than him.
On another note I find it funny that the person who started this whole moon conspiracy theory bullshit is an English Major of all things .... now that is hilarious but of course it does not surprise me!

I don't like at all your first post, FRA...
It is ridiculous to say we lack caring because we don't post on a certain thread.
Come on.
