I recently stumbled across an old turbojet maintenance manual. Included within the manual was a rather nice cutaway illustration, colored in the way that only early 1950’s technical manuals were.

A 300 dpi scan of the diagram has been made available to above-$10 patrons/subscribers.

Little known today is the Northrop MX-334 rocket powered flying wing. Originally designed (circa 1942) without a vertical tail, wind tunnel testing showed that such a tail was needed. Three aircraft were built and flown at Muroc dry lake bed (later known as Edwards Air Force Base), towed into the air behind a Cadillac and then a P-38; once in flight a liquid propellant Aerojet rocket engine would provide thrust.

The MX-334 (as it was known as a glider… when rocket powered, it was known as the MX-324) was intended as a technology testbed and proof of concept vehicle for the Northrop XP-79. This was, like the MX-324/334, a smallish flying wing with a prone pilot. As originally designed the XP-79 was to have a liquid rocket engine; it was eventually built with two turbojets. Unfortunately the single XP-79 crashed on its first flight.

The MX-324/334 was painted in high visibility colors and must have made a striking sight at the time.

After LM: NASA Lunar Lander Concepts Beyond Apollo

As this document is being compiled in 2019, NASA is once again planning a return to the Moon, and new lunar lander designs are being generated. Compared to Apollo, crews are projected to be larger (at least four per mission) and stay times longer (beginning at 6.5 days). However, it is expected that the landers will look much like the designs in this document because, as stated in the introduction, lunar lander design is a response to the simple physics that governs the tasks they are asked to perform. Design is also a living thing. New crewed lander designs will continue to emerge up until the point that humans return to the Moon, and even beyond. New players from different countries and commercial providers will create new designs based on new technologies and new requirements. Until some breakthrough technology or new physics principle is created, each lander will respond to the current physics of lunar landing. There may come a time, generations from now, when future engineers are paging through a digital copy of this catalog and reflecting on the early work of lunar lander designers. “Those Apollo guys were really smart, given that they started with nothing as a reference. The Lunar Module – now THAT was a great lunar lander design.”

It’s an interesting, illustrated catalog of many lunar lander concepts, but it’s hardly comprehensive; it largely starts with the Space Exploration Initiative, largely ignoring concepts from the 70’s and 80’s, and of course focusing almost entirely on NASA_designed concepts rather than Lockheed, Boeing, Rockwell, etc.

The most recent APR rewards included a CAD diagram I created of the “Disney Bomb.” This little known weapon was created by the British in WWII, but dropped by USAAF B-17’s in the last months of the war in Europe. The reason for the unusual name: in 1942 Disney produced an animated propaganda film on the history and potential or military air power. This film included sequences of the war to come, depicting some kinda-sorta sci-fi thinking. Included here is a bomb with a rocket motor, used to penetrate the reinforced concrete roof of a submarine pen. This gave some British engineers ideas… and they made it reality. The Disney bomb was imperfect, but damned if it didn’t work. Next time someone argues that sci-fi doesn’t actually directly inspire engineers to create the future, remember the Disney bomb.

The YouTube version of “Victory” linked below is pretty awful in reproduction quality, but it’s the best I’ve seen (it was released on DVD some years ago).

If you look back to NASA in the mid-1960’s, it certainly seems like it was an organization filled with people who thought that the future was wide open. Apollo was merely going to be the first step; after some landings would come longer-term “camps” on the moon, with stays of a few weeks in temporary habitats; then would come bases that could be visited by multiple crews. Nuclear powered space stations with artificial gravity. There would be manned flyby missions to Venus and eventually manned landings on Mars; as propulsion systems inevitably grew vastly more capable, manned missions to the moons of Jupiter and Saturn would follow in due course.

By the time Apollo 11 actually landed on the moon, though, it was becoming clear that the future was not going to be what it should have been. As noted previously, the production line of the Saturn V was shut down a year before Apollo 11, not only limiting the possible missions of the Apollo program but ending hope for missions that would expand upon Apollo. Shortly after Apollo 11, it seems that morale at NASA was already in decline as the engineers, scientists, technicians and so on could see the writing on the wall. Not only was Saturn dead, but funding was in decline and it was becoming clear that there was minimal political interest in carrying Apollo forward… the job of beating the Soviets to the Moon was done, and the important scientific work, not to mention the prospect of carrying western civilization to the stars, was not that important to the political class who were far more interested in the “Great Society” spending programs. So in September of 1969 a “Seminar on Manned Flight Awareness” was held at the Manned Spacecraft Center, Houston, to deal with the issue:

The successful lunar landing and completion of the flight of Apollo 11 achieved a national objective in this decade and is a significant milestone in man’s continuing progress in space exploration. Historically, achievements of such magnitude, requiring concentrated efforts over an appreciable time period, are followed by a letdown and general relaxation of the personnel involved. In addition, this letdown may be amplified by a serious morale problem when funding cutbacks are experienced. The result is n decline in the required attention to detailed workmanship which can cause a rise in accident rates and potential loss of life.

To counter these potential morale and complacency  problems in the spaceflight program, this Government/Industry Manned Flight Awareness Seminar is  being conducted. The objective of this seminar is the  maintenance of high quality workmanship through effective awareness and motivational programs. We  intend to do this by outlining NASA’s plans for future  programs and the resources being made available to  successfully conclude these programs. In addition,  executives of various industrial firms deeply involved  in space work will present their views of the future.  In this way we can get the message from NASA Management to the individuals responsible for doing the  work that is vital to assuring a high quality of workmanship in the aerospace force.

Not having been born yet, I don’t have any firsthand information on just what was going on at the time in NASA. However, one thing I *do* have firsthand information on was the end of the United Technologies Center/Chemical System Division facility south of San Jose, California, circa 2003-2004. That company was a manufacturer of solid rockets such as the booster separation motors for the Space Shuttle, booster rockets for the Tomahawk cruise missile, Minuteman ICBM stages and so on. It was a vital part of the rocket industry of the United States. And in 2003-2004, it was *obvious* to everyone there that the company was doomed. Things were going wrong left and right to the point that a lot of us were wondering if it was active sabotage; in reality it was merely management and unions working together to make things as ridiculous as possible. Coupled with the fact that the company could, at best, turn in a profit measured at a handful of millions of dollars a year while sitting on *billions* of dollars of prime Silicon Valley real estate, everyone there knew that the companies time was strictly limited. So, what did the USAF and NASA do about it?

The USAF/NASA told the rest of the United States aerospace industry to *not* hire any of us. We were embargoed from seeking employment elsewhere, at least at companies that received federal contracts. So we stayed on the job. Until, of course, the embargoes were lifted, then we fled like rats fleeing a sinking ship.

It seems that NASA in September 1969 was facing a similar predicament. Everyone there – scientists, engineers, technicians and subcontractors of all kinds – could see the writing on the wall. And when you know that the project you’re working on has a near-term end date, you look for somewhere else to be, preferably before all your co-workers get the same idea. This is sensible, but it’s also a problem. Yes, Apollo/Saturn had a distinctly limited lifespan. But the program still had a number of years left, and it would need the bulk of the staff to stay on the job to make sure that the spacecraft and launch vehicles were finished, maintained and prepared for their missions. If everyone at NASA fled for brighter opportunities elsewhere, the missions still funded would be unable to be completed. So NASA held a seminar that seemed to have the singular goal of convincing people just how bright NASA’s future really was. A space shuttle would be available by 1976 and a space station by 1979… as well as a polar orbit station and one in geosynchronous. A lunar orbiting station around 1976. Nuclear powered inter-orbital shuttles. Manned missions back to the Moon and on to Mars.

It was all wrong. Yes, the Shuttle finally arrived in the early 1980’s, greatly delayed and vastly and permanently over budget, each flight costing one to two orders of magnitude more than originally projected. yes, a space station did eventually arrive… in the 1990’s, handicapped by international politics, small, undermanned, under-capable. None of the rest of it even *tried* to happen. The seminar reads like desperation, or a rah-rah session at some multi-level marketing scheme; I had flashes to scenes in the recent Hulu series “Dopesick” where Oxycontin sales reps are getting the latest BS about how great the next dosage of the pill will be, so go out there and sell more.

*A* future does not mean *A* *GOOD* *FUTURE.*

No. It was the end, and apparently everyone involved could see it.

My book on the B-52 is now being printed (I understand that copies physically exist), so it is perhaps a little late for additions and revisions. Still, I remain on the lookout for relevant information. To that end I recently plunked down a fair chunk of change for a pair of documents on ebay… a set of blueprints of the B-52G cockpit, and a B-52G mockup review. I eagerly await their arrival. I have high hopes that the US Postal Service won’t drop a tractor axle dipped in anthrax onto the package.

These will likely end up in the catalog for monthly rewards. If they are of interest, and/or if you would like to help fund the acquisition and preservation of such things, please consider signing on either for the APR Patreon or the APR Monthly Historical Documents Program.

Back in the day, aerospace companies would actively court the public, including those crazy kids who liked to make models. To that end, a number of aerospace companies would release surprisingly nice diagrams of their aircraft. North American Aviation was one such company, and one of their aircraft that they diagrammed for the public was the A3J-1 (later A-5) Vigilante supersonic carrier based bomber. Oddly, I’ve had trouble finding the full scale print of this… but then, I’ve had trouble finding *most* of the ones released by North American. Seems that they tended to not survive to make it to ebay. However, I recently acquired a copy of an old magazine that had the Vigilante diagram, reproduced reasonably well. Woo.

A 300 dpi scan of the diagram has been made available to $4 and up patrons/subscribers in the 2021-11 APR Extras Dropbox folder. A 600 dpi scan has been made available to above-$10 patrons/subscribers.
