I´ll bet that you have never heard about this 1996 speech by Bill Wood, a close friend of Bill Kaysing:
http://www.hawken.edu/ptra/archive/msg01616.html The speech was posted in a forum on February 15, 2002, by fellow debunker Carol Balfe. She does not mention exactly from where she has the transcript of Bill Wood´s speech, but these are her own comments: "Hi Steve and others, I found the doc that I was given citing some of the "Moon Hoax" ideas. Since it seems to be floating out there so prevalently, you may as well see some of the arguments -- all of the "conspiracy theory" variety -- Pseudo science is alive and well!! I think it can be an opportunity to help students examine ideas like these critically!! Anyway -- here's the text -- that contains a reference to a book about all this stuff. The author claims to have been an engineer and therefore "in the know." And then follows a HUUUUGE transcript of HB Bill Wood´s speech. These are but a few quotes from this speech: "William (Bill) Wood presented this speech to an audience of 90 people in San Jose, California in 1996. **The title of my talk today is “Did we ever go to the Moon?” *About half of what I’m presenting today is extracted from Bill Kaysing’s book, We Never Went to The Moon, which I highly recommend. Anyone who is interested can obtain one from him for $20, including shipping. See me afterwards for the address. The rest of what I’m presenting today comes from my own 30-year investigation." And .. "**In the Apollo photographs there are no stars in the lunar sky. No crater was produced by the rocket exhaust under the LEM. Recent tests with the DC-X rocket, landing tail first on Earth, produced a large, 2’ deep crater and significant damage to the vehicle. The crater was so large that there was concern that the DC-X might fall over, into it. On the Moon the crater would have been much larger, due to the Moon having only 1/6 as much gravity as the Earth and no atmosphere. In the Apollo landings, there was no Moon dust on the landing pads in spite of the fact that Armstrong talked about all the dust he was kicking up. In photos, Moon dirt is clearly defined out to a certain distance, then there is an abrupt transition to a fuzzy enlarged photo of lava flows in Hawaii and Utah used for background. Prior to Apollo, top geologists were asked what they expected lunar soil to be like. Afterward, they were provided with just what they expected: nothing not found on Earth." Lava flows in Hawaii and UTAH, eh ? Oh, Jaaayy, any comments on these lava flows in Utah ? [img]/phpBB/images/smiles/icon_smile.gif[/img] "**As in the 1974 movie Capricorn I, Apollo missions took off with no astronauts aboard and went into orbit. Then the 3rd stage took an unmanned spacecraft to the Moon, where it performed a lunar landing, lowered a seismometer, ejected a laser reflector, transmitted back prerecorded manned audio and video, then dug up Moon rocks and returned them to Earth. Later, the crew in a burned capsule were dropped from a C-5a aircraft into the Pacific for recovery. Some of the real Moon rocks were then traded with the Russians for real Moon rocks they has just obtained with their own unmanned lunar lander and return craft. Larger amounts of phony Moon rocks were manufactured on Earth and sent to laboratories for analysis and put on public display."

As usual Jay smashes the competition. One thing to add.
The RL-10A-5 engines that the DC-X used have a thrust range of 4,500 to 15,000 pounds. So it is basically 18,000 lbf vs 3000 lbf for the LM. It's probably closer to 22,000 to 25,000lbf, when accounting for the fuel. In the G. Harry Stine Book, Halfway to Anywhere, which is a book devoted to Single Stage to Orbit vehicles, with about half covering the DC-X, there is a nice photograph of the "blast crater" in the sand. The author calls them four small potholes. The ground is not burnt or melted or anything like that, even with the higher burning temperature fuel of liquid hydrogen and oxygen. The four craters each are about 2 feet across and maybe a foot deep. http://www.amazon.com/exec/obidos/AS...102443-9702213 If I find the photo on the Internet I'll post it. <font size=-1>[ This Message was edited by: jrkeller on 2002-07-07 23:58 ]</font> |

Oh my aching ribs! thank you for cheering me up on a rather drab Monday morning. That 3rd stage vehicle was some piece of work, eh? I bet we can't construct anything like that right now. Gosh how technology has slipped in the past 30 years.

Bill Kaysing worked at Rocketdyne for over 7 years (1956-1963) with a secret security clearance ...
Just to add... I applied for a job with the IRS while in college. As part of the application process, I was investigated and givn a Secret security clearance. This is the minimum security clearance there is. As Jay implied, it doesn't mean you will be privy to "gubmint secrets" but that you can be trusted not to speak out of school. And Kaysing himself puts the lie to that. The Saturn 5 was supposed to contain over 2 million parts, an impossible reliability nightmare. No. Part count is only one measure of reliability. Factors such as linearity and coupling also affect the reliability of a system. In fact, the Saturn V is a much more loosely coupled system than, say, a Boeing 747 which has about six million parts and was also being developed at this time. So, you're saying the 747 can't really fly? That the airlines have been tricking us all these years? Will the conspiracy never end?! The LEM was poorly designed, with 2 doors instead of one, adding critical weight and reducing interior space and safety. False. The LM was brilliantly designed ... the LM is often praised as the most innovative and "pure" vehicle design of the 20th century. Just wanted to emphasize this. In the Apollo photographs there are no stars in the lunar sky. This from a man who claims to have a baccalaureate and a master degree in engineering, and three other unspecificed degrees in highly technical fields, including physics and chemistry? Degrees which don't make him an expert on astronomy or photography, but which do make it sound like we should pay attention when he speaks. Recent tests with the DC-X rocket, landing tail first on Earth, produced a large, 2’ deep crater and significant damage to the vehicle. Hm, DC-X at 16,000 kg in earth gravity versus a 7,000 kg lunar module in lunar gravity. Could there possibly be just a tad more thrust involved with the DC-X? Now, here's where all those degrees should come in to play. So, why didn't he use one or two of them? He seems to be taking only the facts he wants to use... 1/6G so the same force should have 6X the effect as on earth... but ignoring the others... 1/6G so you don't need the same force. The factors that affect cratering are... And, of course, ignored these, too. Did he resign from the Apollo Program in 1970 out of disappointment that we weren’t really going? In 1970, NASA asked von Braun to move from Marshall Space Flight Center where he was Director to Washington, D.C., to head up the strategic planning effort for the agency. Less than two years he decided to retire from NASA and go to work for Fairchild Industries. He died in 1977. Looks like Wood was guilty of some of that "lackadaisical attitude" Kaysing noted. _________________ <font color=000099>Never attribute to malice what can be adequately explained by ignorance or stupidity.</font> Isaac Asimov (fixed Code) <font size=-1>[ This Message was edited by: Jim on 2002-07-08 09:06 ]</font> |

Maybe, but it'd cost ya. Unmanned soft-landing on the moon was possible. Remember the Surveyors. But of course the Surveyors didn't always work. Unmanned pinpoint landing is even harder. Now try it with a vehicle the size and complexity of the proposal. Sample-return, deploys various precision-aligned equipment, and plays a two-hour (or 24-hour, for the J-mission) prerecorded EVA video. Heaven help us if the VCR jams up there. And who built this thing? The original argument was that NASA and its contractors were technically inept and managerially lackadaisical. Yet they come up with this miraculous piece of equipment to do all this stuff by automation and/or remote control. Why not just put a couple of pilots on the dang thing in order to simplify its design, and call it a lunar module? |

Sure, all you need is a Perl script that inserts the phrase, "Very interesting, sir or madame; do you have any evidence to support that?" after each paragraph. Do you have irrefutable proof - know that phrase? - that you really exist? The IRS seems to think I do. Do you want to argue with them? |

I'm sure Kaysing had a security clearance of some sort. He couldn't have done his job without it. But he's not the first conspiracy theorist to try to bolster his credibility by touting a real or imagined security clearance. The problem is that it's always a two-edged sword. I'm sure you were told about the very draconian penalties for violating the terms of a security clearance, and the little white card you sign which waives your right to trial in such matters. Given that the U.S. government appears very serious about its security clearances, how are we to interpret the actions of alleged holders of these clearances? You can go to jail just for telling your mother about secret information, and these guys are writing books and going on television? Can anyone explain to me why the FBI can't seem to catch them? The obvious answer is that the tales these folks are spinning have nothing to do with anything they might have learned as a result of their security clearances. The whole idea of a security clearance is to prevent just such an occurrence. But the real answer, as I said, lies in the structure of Bill Kaysing's case. He stands up and claims to be an insider. But his evidence consists of things that anybody could have found out: photo anomalies, etc. Kaysing may have had a security clearance, but compared to his argument that's just a big smelly red herring. So, you're saying the 747 can't really fly? LOL! No, I'm putting the Saturn V in perspective. Most large-scale engineering projects have parameters that would impress or frighten the layman. Two million parts sounds like a lot to people who have trouble with a 100-part kitchen toaster. But of course professional engineers have ways to manage that complexity. The Boeing 747 has about six million parts, or three times as much as the Saturn V launch vehicle. It was rolled out in 1968, if memory serves, about the same time the Saturn V became a viable machine. Bill Wood wants to make the Saturn V sound like some impossible engineering nightmare that couldn't possibly have been accomplished because it had two million (gasp!) parts. That's very misleading, and someone with as extensive an engineering background as Mr. Wood purports to have shouldn't be making that sort of argument. In engineering terms, the Saturn V has only two million parts. Another thing to consider is that the Saturn V is a three-stage rocket, and each stage was given to a different company to design and build: The S-IC first stage went to Boeing (while it was building the vastly more complicated 747, I might add), The S-II second stage went to North American Aviation, and the S-IVB third stage went to McDonnell-Douglas. Divide and conquer. The issue about linearity and coupling is very important. The Saturn V is a modular design. The S-IVB, for example, can work either as the Saturn V third stage or as the S-IB second stage. What does that mean? It means that the design and operation of the S-IVB is largely independent of what you stack above or below it. That greatly reduces the coupling in the system. There's very little the S-IC or the payload can do to affect the operation of the S-IVB. That means it can be designed, built, tested, and certified independently. It's not a matter of throwing all two million parts together and hoping they work. Compare that to a 747. While it's not true that each part affects the other six million parts in the design, it is true that the 747 is not modular. You can't detach the wings and hook other wings on. You can't partition the design up into large segments and say that the operation of each segment is unaffected by other segments. Sure, you can put different engines on, but those are made by someone else anyway. That's a "design interface" problem. The point is that Mr. Wood isn't giving us the engineer's point of view. He's simply reinforcing the incorrect layman's view of large scale engineering and how it affects reliability. The 747 is a highly reliable design, and according to Mr. Wood it would have been three times the nightmare of the Saturn V, which he says is an unreliable design. Degrees which don't make him an expert on astronomy or photography ... You can't get a physics degree without taking astronomy classes. You can't get a chemistry degree without knowing about photochemical reactions. While you can say he might not personally have acquired the necessary special expertise to cover this question, consider that he claims to have researched these questions for 30 years, and the statements in question were given in 1996. Surely by that time someone would have said, "Uh, Mr. Wood, that's not a supportable argument." Let me be frank. I don't think Mr. Wood actually holds all the degrees he claims. Let's break it down. Quote:
Quote:
The point is, he isn't designing the things, he's just following the steps in the maintenance manual intended for use by your average airman. Of course he'd have a security clearance. You don't even get to see the service manual without a clearance. The point is that all this happened before he got his degrees from the institution he named. Quote:
When did he get them? His resume has him working on various projects from his graduation from CalPoly in 1976 right up to 1993, three years before making his claims. Sure, I worked professionally while working toward advanced degrees, but I certainly couldn't have kept up that pace through three highly technical degrees. Continuing on, Quote:
In any case, if Mr. Wood was familiar with the Delta launch vehicle, we wonder why he has such a problem understanding the LM ascent engine. The Delta second stage uses an Aerojet engine which is an almost exact double of the TRW LM ascent engine. It's about the same size, produces the same thrust, and burns the same fuel. Is Mr. Wood playing dumb, or is he padding his resume? Quote:
To this point he hasn't been specific about what he worked on with these projects. His arguments below discuss supposed irregularities with propulsion, yet he doesn't say what he did for the Delta program, or for his "various classified projects". The problem is that "Bill Wood" is a pretty common name, and so it's easy to verify that a certain "Bill Wood" did this, and a certain other "Bill Wood" did that, but we can't verify that they're this particular Bill Wood. There's a Bill Wood who works on propulsion at the University of Michigan, and one who works on propulsion at Stanford, and a Bill Wood who wrote a proposal to NASA. There's also a Bill Wood who is well-known in California in the field of model rocket propulsion. Now model rocketry requires expertise, but one can be a model rocketeer without having the required expertise to say definitively that the F-1 engines wouldn't have worked. Quote:
Quote:
Quote:
The problem is when he goes to criticize the F-1. The plume, he argues, is "fuel-rich", meaning that the plume contains unburnt fuel. This is an indication of combustion inefficiency -- fuel which should have burnt in the combustion chamber to produce thrust is being ejected unburnt where it burns non-propulsively in the atmosphere. Since all the hoax books, sites, and videos mention no more about Mr. Wood's claims than what has been given on the site under critique, we wonder what Mr. Wood believes is suspicious. Plume incandescence, perhaps? The Saturn V sure does have a bright exhaust plume. Might Mr. Wood have mistaken incandescence for combustion? Unfortunately the LOX/RP-1 bipropellant is known for its highly incandescent flame, and the best examples of it are the very Delta rockets that Mr. Wood claims to have worked on! What does he say? Mysteriously, the F-1 exhaust plumes are dark for the first 8’ after the end of the nozzle, then ignition of a very fuel-rich exhaust plume occurs in the atmosphere. You probably know the clip in question. It starts with a dark, grainy image looking up the skirts of a Saturn V. You see cryogenic oxidizer cascading from the nozzle in slow motion followed by the ignition. Then the view shifts to pad level and you watch the rocket rize slowly. As you see the nozzles rise above the MLP, you can see a portion of laminar flow, and underneath it a brighter turbulent flow. Mr. Wood theorizes that there's a smaller engine hidden inside the F-1, and they just squirted additional kerosine into the space between the "little" engine's nozzle and the "big" F-1 nozzle and lit it up for a light show. Well, any propulsion engineer can tell you that's a good way to blow your nozzle into a million pieces. Why do you think they make all those sparks under the space shuttle's engines? Cardinal rule: Thou shalt not burn thy fuel in thy nozzle, lest it go to pieces and smite thee. Further, if the combustion took place outside of the nozzle, it would produce a dramatic spheroid fireball, not an 800-foot sufficiently laminar plume. The F-1 nozzle ration was optimized for sea level, to provide the most thrust at launch. (The N-1's engines were optimized for about halfway through the first-stage burn.) The Saturn V's plume just after launch is only about twice the diameter of the rocket itself, and almost perfectly cylindrical. That's a textbook plume. Apparently Mr. Wood doesn't realize his "dark plume" argument is based on footage taken from a high-speed armored DAC and thus is trememdously underexposed. Though taken in daylight, most of the rest of the frame is dark. It's only when the F-1 plume becomes visible that the frame is sufficiently lit. Not only does this plume completely saturate film at normal exposure, we even get optical scattering in some lenses, centered right at the nozzle where the plume would be brightest. The plume is not "dark" coming out of the nozzle, it's merely very slightly darker than the more turbulent flow beneath it. In terms of human visual perception both would be too bright to look at with the naked eye. Mr. Wood's statements about "combustion instability" are fairly misleading. "Combustion instability" is a catch-all phrase in rocket engineering which is equivalent to the automotive, "My car's making a funny noise." What was really going on was that the injector scaled up from the H-1 design wasn't working. And the problem wasn't "suddenly" solved; it took Rocketdyne 12 months to design a new injector that damped out the instability. The injector is basically just a big showerhead at the top of the combustion chamber that sprays fuel and oxidizer in a pattern for optimal combustion. That's hard to determine. It's easy for flow characteristics to alter the pattern, which in turn alters the flow characteristics and you get a divergent feedback that blows your engine apart. Here's an example of divergent feedback. It's one of those "don't try this for real; just think about it" experiments. Accelerate down the street in your car. Now reach down and pull the release by which you adjust your seat. Since you're accelerating, you'll slide backwards. This pulls your foot off the accelerator, and your car begins to slow, This pushes you forward on the rail, which puts your foot back on the pedal and you accelerate, and back you go again. Now imagine those oscillations getting worse and worse each time. That's divergent feedback. Once the Rocketdyne engineers found a suitable dynamically stable injector design, they simply had to refine it to damp out induced instabilities. That is, you find an injector that won't spontaneously develope an instability that diverges and blows up your engine. But what if something causes the fuel flow to fluctuate? What if something bangs on the size of the nozzle? You have to find a design that naturally damps out these effects. Truth be told, they never actually got this fixed. The Saturn V was known for its "pogo" effect -- longitudinal vibrations caused by combustion instabilities. They just figured out how to work around it and limit its effects. In 1970, NASA asked von Braun to move from Marshall Space Flight Center where he was Director to Washington, D.C., to head up the strategic planning effort for the agency. Yes, to be sure, Mr. Wood gets his dates wrong. More than once. But the underlying concept is what's at issue. Mr. Wood insinuates that von Braun left NASA because NASA wasn't really going to the moon. That's consummate question-begging. I imagine a hypothetical situation along these lines: "Yes, Mr. von Braun, we know you've been very helpful designing our spacecraft and getting us to the moon, but that's going find now without your supervision. We'd like you to take a job in Washington D.C. where you'll be sitting in meetings all day with politicians and bureaucrats who will disagree with you just for the sake of disagreement. How does that sound?" And then along comes Fairchild and says, "Gee, Mr. von Braun, you're the most brilliant aerospace engineer that this century has ever known. Why does NASA have you sitting in meetings all day? Tell you what: we'll hire you as our V.P. of engineering, and you'll get to supervise all our design engineers and come up with great designs." It's clear von Braun wasn't happy at NASA anymore, but the question is why he wasn't happy. The hoax believers just assume it's because of the reason they've postulated and go from there. It's all very circular. |

The man actually suffered a stroke, and was left unable to talk.
That's no excuse for having given half an argument (if even that) for decades. Yes, in 1958 there were many problems with going to the moon. They were solved in the subsequent decade. Mr. Wood claims to be an expert in the industry that solved those problems. Other experts in the industry speak freely about having solved those problems. (Just try to shut them up.) Mr. Wood is clearly splitting rails and I want to know why. |

Myself: The man actually suffered a stroke, and was left unable to talk.
Jay: That's no excuse for having given half an argument (if even that) for decades. You are joking, surely? Perhaps he has elaborated on this and we just don't know about it yet? After all, I have never seen this transcript before today but, evidently, he gave this particular speech some time ago. We know he talked a little bit on the WHotM? video, but it would seem that shortly after this he suffered a stroke. |
|

|
You are joking, surely?
I am most serious. Rail-splits are inexcusable. It is Wood's responsibility as an expert lecturer to establish for his audience the proper context for his statements. To say something is suspicious because certain problems once existed with it -- without discussing how those problems were subsequently solved -- is dishonest. You want me to believe that Wood just innocently neglected to mention the part of the story that completely undermines the point he was trying to make, and that if we just dig farther we'll find it. I'm not that naive. I have never seen this transcript before today Strange. It is almost verbatim what Wood contributes to Dark Moon on pages 127-128, which you claim to have read. |

This thing about the LM proposal only being 100ish pages long, when other proposals for other projects contained thousands...
I've just read Tom Kelly's Moon Lander and it specifically states that the proposal, without apendices etc, was limited to 100 pages by NASA. It even states that during the final printing, it was found to be half a page too long and Kelly and a colleage went through the whole thing taking out singlw phrases and sentences to bring the document in under the hundred page limit. All the proposals for Landers by all the companies asked to sumbit were under 100 pages. That's what NASA wanted. DC-X craters... Let me get this straight. The DC-X has five engines, each of which produces much more thrust than the LM DPS at landing. The DC-X keeps it's five engines firing until it has actually landed, unlike the LM which fell unpowered the last eight feet. The DC-X is very tall and slim, liable to topple, with retractable legs whereas the LM was short and fat, with legs that were extended once and verified locked in place before a landing was attempted, to enable it to be 'dropped' onto the surface quite safely. Even though the DC-X is set up to be more likely to produce craters and is operating to make craters more likely, it only produces craters two feet wide and one foot deep. This argument should make it less likely for a crater to be observed under the LM, not more likely. |

So that's the in depth investigation you claim to have done. Watched the vid, couldn't be bothered to read the book. How many of us have spent hours trawling through the ALSJ or the NASA photo archives to find a particular picture or a quote that answers a particular and obscure claim? Karamoon, go read some books, then come back with a coherent argument. I've read both sides of the argument. I actually read the HB stuff first, and I did indeed get angry. I wanted to verify what they'd claimed. Then I got really angry at the HBs for trying to take me for a fool. |
|
|||
|
Most HBs claim they 'stumbled' across the Moon Hoax by accident, and they got angry because they had been lied to, ie NASA had duped them into believing man had walked on the Moon. I also got angry at this thought. I then did a bit of backup research, just to see if they'd got their facts straight. They had not. I got angry at the fact that the HBs had tried to con me. Their subsequent behaviour (not answering questions, ignoring relevent facts, selective presentation of evidence and deleting whole web forums) has forced me to the conclusion that the Hoax is a con, to make money from the unwary. That's what makes me angry.

John,
Your experience is almost identical to mine and I even work for a NASA contractor. When I watched the fox show I thought that most of their claims at least had some merit. When the show got to the blast crater part, then I knew that they hadn't researched anything on this topic. At the time of the shows airing, I had spent about five years researching and analyzing blast craters. It's really more like lack of blast craters. The entire process is a very complex, fluid mechanics and heat transfer problem and what I heard made me gag. After that I have researched the Moon hoax topic to death. I have yet to find anything that even remotely sways me to believe in the moon hoax. I'm more convinced than ever that it happened. When it comes to to heat transfer, thermodynamics and fluid mechanics, my expertise, they have violated the first and second laws of thermodynamics just to make their points. I also believe that most of these people are just con artists and that they really know that Apollo did land on the moon. <font size=-1>[ This Message was edited by: jrkeller on 2002-07-08 23:46 ]</font> |

The hoax arguments were first presented to me in a way which immediately led me to think there was nothing behind them. They were so obviously ill-conceived. I've studied them extensively in the intervening years and in some cases spoken with their chief proponents. While I can't speak to their motives, I can definitely say that they go to great lengths to avoid and suppress the contrary evidence. That's suspicious.

Generally weight-loss schemes don't involve unfounded accusations of large-scale fraud and calling people liars who risked their lives in the exploration of space. Neither do they impugn the honor of an entire industry, in which I once worked and in which I still have many friends. Instead what you mention falls generally under caveat emptor.
Sell someone a sugar pill or a "balanced resistance coil" (i.e., a helical spring) at an exorbitant price and tell him he'll lose weight, and what do you get? Someone who's just as fat and somewhat poorer. Eventually, if he's smart, he'll quit buying the stuff. Plop a kid down in front of the Fox program and what do you get? Someone with a distorted and factually incorrect understanding of logic, science, and history, some of which will stay in his noggin for the rest of his life. Yes, it makes me a bit angry to see ineffectual products being greedily sold to a trusting public. But I talk about the moon hoax theory because I believe there's more at stake there, and primarily because that's where my expertise lies. I assume that there are qualified dieticians out there to debunk the latest weight-loss fad, if they feel the need. |

There does indeed seem to be a section of the exhaust plume from the F-1 engine that is objectively dark. It's visible in at least two Saturn V launch photos I have in my possession, as well as the famous footage you described above. It extends from the bottom of the engine bell for about 2/3 the size of the engine bell below it -- maybe 4-5 feet. It is very dark indeed -- much darker than the sunlit sides of the S-V, and far, far darker than the incandescent (and greatly overexposed) exhaust plume below that. It's a sort of golden brown color. The effect is so clear and surprising that for a long time I assumed that the F-1 engine had a long "skirt" of some relatively thin metal, through which the brilliant exhaust plume was visible. However, I have now seen pictures of the F-1 that show very clearly that the engine bell ends above this dark region. One unambiguous marker is the plumbing for the LOX coolant that wraps around the bell about halfway down. The dark plume is clearly not part of the engine bell. I have a couple ideas about what might be causing this effect, but they would be pure speculation at this point. However, one thing I would argue strongly: the dark portion of the exhaust plume is really dark, and would be no harder to look at directly than any other sunlit scene, if the incandescent plume were not present. If anyone has definitive information about the causes of this phenomenon, I'd be very happy to learn more. Quote:
Incidentally, Rocketdyne tried a lot of things to fix the F-1 problem, including changing the position and angles of the LOX and fuel sprays, moving the impingement positions somewhat lower in the combustion chamber (at a cost of some engine efficiency), and adding baffles to the injector plate (which had to be cooled by circulating LOX). None of these was a "magic bullet", but in combination, eventually the F-1 became so stable that they could detonate a small bomb in the combustion chamber, and the resulting oscillations would damp out within 100mS. |

There does indeed seem to be a section of the exhaust plume from the F-1 engine that is objectively dark. It's visible in at least two Saturn V launch photos I have in my possession, as well as the famous footage you described above.
That would be interesting. Any way you could scan those photos? I've only seen this effect in the underexposed photos. I'm reluctant to comment further until I can see what you're looking at. But wasn't pogo a problem mainly with the second stage? Come to think of it, you might be right. I'll have to go scour through the S-5 performance reports and make sure. |
