Hey! Anybody hereabouts interested in unbuilt variants of the North American B-70 bomber? I know a guy who can hook you up:

Construction is underway of an unmanned rocket-powered aircraft to be carried by the Stratolaunch “Roc” aircraft. The Talon-A is supposed to be something like the proposed X-24C… a lifting body hypersonic platform that can have various experimental units – including scramjets – attached to it. The Roc would be capable of carrying three Talon-A’s at a time, though it seems unlikely that there’s a really good reason to do so.
This art was posted a decade ago. But behold! Now there’s dimensional and weight data. Woo.
An early-1960’s idea for a one-man “space pod.” Similar in concept to von Braun’s “Bottle Suit,” the Remora would allow an astronaut to work in a more comfortable setting than a full pressure suit, while giving the astronaut more tools and greater protection from radiation, meteoroids and other space hazards.
The name “Remora” comes in part from the fact that the “suits” would not, unlike normal EVA suits, have to be put all the way through an air lock. Instead, the “head” of the Remora would enter a small port on the spacecraft, lock in, the pressure would equalize and the transparent dome would open allowing the astronaut to climb right out. The pressure in the spacecraft/space station would be the same as that within the Remora, meaning no prebreathing and no dangerous and time consuming steps up and down in pressure. The art shows the astronaut wearing a pressure suit; this would presumably be a safety measure in case the Remora was breached. So long as the Remora stayed pressurized, the astronauts suit could have had little to no relative pressure, meaning that it would not be stiff and difficult to work in. The Remora was to be equipped with a reaction control system of some kind, but exactly what remains unclear. Options would include:
1: Cold gas, like pressurized nitrogen
2: Monopropellant like hydrogen peroxide or hydrazine
3: Bipropellant, either hypergolic storables or something like hydrogen peroxide/kerosene. Cryogens seem unlikely.
The Remora was clearly meant to remain tethered to its spacecraft/space station. One wonders if the astronaut was supposed to remove his suit gloves before putting his hands into the external gloves of if the one would fit in the other. Additionally, it seems like there should have been little pressure doors on the inside of the glove in case a finger gets punctured.

A black and white bit of concept art that was sold on ebay a while back showing the Lockheed STAR (Space Transport And Recovery) Clipper space shuttle concept from the late 1960’s. This was a promising concept that used a lifting body orbiter with a wide, flattened rear fuselage that was liberally covered with rocket engines (a large range of engines and layouts were considered, including liner aerospikes). The shuttle was filled with liquid oxygen tanks and some hydrogen tanks; the bulk of the hydrogen was stored in a large V-shaped drop tank. This component would have been larger but reasonably inexpensive, jettisoned after deletion to be destroyed during re-entry or splashdown in the Indian Ocean. The vehicle would have continued on to orbit using the propellant remaining in the internal tanks.
A vast amount of information on the STAR Clipper is available HERE.
The STAR Clipper lasted a lot longer than many contemporary designs and went through a multitude of design revisions. it always seemed like it should have worked reasonably well… and it had the benefit of being aesthetically beautiful.
A piece of art that was on ebay a while back depicting a C-130 Hercules converted into an AWACS-like aircraft by the inclusion of a radar rotodome to the top of the vertical fin. This may look a little odd, but it was a good position for such a radar system as it puts it above all aircraft components.
