Have you ever wondered to yourself “what were the Air Force Weapon System Designations as of September, 1959?” Wonder no more:
The following page does not continue the Weapon System list, but goes on to list Air Force ace fighter pilots.

HOTOL (HOrizontal Take Off and Landing) was a British Aerospace concept for a single stage to orbit airbreathing launch vehicle, originating in the mid 1980’s. It was a stellar example of aerospace optimism; like its contemporary the X-30 National Aerospace Plane, it relied on a propulsion system of spectacular complexity and stunning lack-of-actual-existence to function. As originally conceived it was supposed to have an RB545 engine; unlike the X-30’s scramjet engine, the RB545 was an air breathing rocket engine. Liquid hydrogen would be used to liquify incoming air, a portion of which would be turbine-fed into rocket engines to burn with the hydrogen. Due to some amazing bureaucracy, the engine was slapped with the “Official Secrets Act” which meant that it was so amazing that it had to be classified… so classified that it basically couldn’t be worked on. Genius! Whether it would have actually worked any better than NASP’s scramjet is anyone’s guess. In the going on forty years since the RB545 was dreamed up, it obviously hasn’t driven an aircraft to orbit. Or, it seems, off a runway. Like the scramjet, it *might* work, if only the development effort was properly funded and allowed to work through issues, rather than starved and throttled.
The early HOTOL configuration shown here would have taken off using a ground trolley in order to save on landing gear mass. The vehicle was nominally unmanned, though crew and passengers could be installed in a module in the cargo bay, located well aft. One problem the configuration had was substantial center of gravity and center of pressure issues, driven by the long, slim fuselage filled with sloshing and emptying hydrogen tanks. As memory serves, this remained a problem throughout the design lifetime of HOTOL.

HOTOL was a 1980’s/90’s British Aerospace idea for an airbreathing SSTO spaceplane. As with all such designs to date, it came equipped with a heavy load of optimism; physics, however, does not care about your sunny worldview, and like all other airbreathing SSTOs to date, the design simply could not be made to work with existing materials, propulsion systems, politics and economics.

Just bought on ebay, a print of the Boeing “Space Sortie” vehicle.
So much for my “maybe I should spend less in these difficult times” idea.

In March of 1961, “Space World” magazine published a few articles about what the future would look like thanks to the onrushing new technologies of the space age. It is… well, it’s wrong.
The article is jam-packed with predictions of a glorious technological and economic future to be brought about by the Space Age. And from the standpoint of 1961, it probably made sense: technology was advancing by leaps and bounds, the budget for NASA was beginning to explode, overall space and related science spending by both government and industry were shooting upwards. It *should* have been a glorious new age. But the experts did not count on a few things. Viet Nam, for example and, worse, LBJs “Great Society” economic and social suppression/dystopia promotion programs.
Some of the predictions for 1971:
1) The “Space Industry” would be the biggest industry in America
2) The “middle class” would be working high-paying skilled jobs and would make up 80% of the population
3) Skyscrapers would dwarf the Empire State Building, using girders made from beryllium, tantalum and niobium
4) Tape recorders would be the size of a cigarette
5) You could easily send a fax from, say, New York to Australia. You’d scan the page, beam it up to a satellite passing overhead, the satellite would store the scan and, when it some time later passed over Australia, the fax would be beamed down. That’s… not how international satellite communications works, but OK.
6) There’d be cities in Antarctica
7) There’d be regular, routine and affordable suborbital rocket passenger transport. Such as from Antarctica to New York, several flights a day.
Amusingly, these predictions are considered likely to be too conservative; people would look back to the predictions and “wonder why the prophets of 1961 were so shortsighted.”
“Today it is rocket time, and the coming decade will carry us all into the Age of Astronautics.”
They could not have known that their glorious future would only last a small handful of years. By 1968, the Apollo program was already terminated, with no follow-on. And the maximum spending for NASA occurred only in 65-66 or so, peaking at about 4% of the federal budget. Imagine if the upward trend had continued to, say, 1970. Perhaps 6, maybe 8% of the federal budget. What a world it could have been.
Awww. I gave myself a sad.
Sigh.

Radian announces plans to build one of the holy grails of spaceflight
The “holy grail” in this case is an SSTO spaceplane. It is to *not* incorporate airbreathing or wacky unproven technologies; instead, it is to use fairly conventional liquid propellant rocket engines in the tail of a cranked-delta spaceplane. To lob it off the ground, it will use a powered sled for a horizontal runway launch.
Ehh.
Same basic concept as the Sanger Silverbird of 1944 vintage, or the Boeing “Windjammer” and RASV concepts from the 70’s. If they can get the mass ratio to work… sure, it’s possible. They’re claiming a 48-hour turnaround. Uh-huh. I’ll believe it when I see it. I wish them the best, but I’ve seen far too many such press releases since the 90’s to get all excited.
A few patent applications that might be of interest:
“Earth to Orbit Transportation System”
“Rocket propulsion systems and associated methods”
The not terribly enlightening website is here:
https://www.radianaerospace.com/
Curiously, one of the names attached to both patent applications that might be of interest to readers of this blog is Gary Hudson, of the Phoenix SSTO, Air Launch and Roton fame. But he doesn’t seem to be listed on the website.

All I have is this single page. This would be from the 1980’s, probably before or concurrent with the X-30 NASP program. The range of possibilities for hypersonic cruise airbreathing vehicles is pretty remarkable.
