Alternate History
Dyna-Soar soars into orbit!
On February 20, 1962, Dyna-Soar 3, piloted by US Air Force Astronaut Jim Wood, achieves orbit, making him the first American to orbit the Earth. The space vehicle stays in orbit for four hours, before descending and safely landing at Edwards Air Force Base.
This monumental achievement by the US Air Force encourages the Kennedy Administration of the Air Force's ability to lead the US space program. Because of this further funding for US Air Force space projects are given, paving the way for the US military's increased presence in space.
Carruthers - DYNA-SOAR
"... Not sure where the name "Carruthers" comes from, but they're the faceless builder that's associated with the infamous Dyna-Soar fuzz (from the early 80s). Most notably used by @kimletgordon , the original Dyna-Soar is a super heavy, sludgy Big Muff clone of sorts. The "Lite" version, which I've had for over a decade, is essentially the same circuit but with a strange configuration of the transistors that make it sound more like a chunky overdrive than a fuzz. Interestingly enough, the one I have was modded by the previous owner back into its original Muffy glory! So I had been waiting and searching for nearly 13 years to find an actual Dyna-Soar to compare it to, and finally last week I nabbed one. 😎 Both are pretty intense with the amount of gain that's available. The only other Muff style pedal that comes close would be the Maxon OD-801. The modded "Lite" I have is oddly articulate, even at the highest gain setting, but still punishing. While the regular Dyna-Soar has a mountain of low-end that can dooooooom for eons..."

Proposal: Dyna-Soar/Little Joe II Suborbital Flight Test Program

"The X-20 Dyna-Soar program is often remembered as one of the biggest lost opportunities in the history of manned space flight. Evolving from the WS-464L Program, Dyna-Soar had great potential for use as a military space platform as well as civilian science laboratory. Unlike the earlier Mercury, Gemini and Apollo capsules that were single-use vehicles returning to earth under a parachute system, the X-20 was a winged vehicle, capable of landing on select runways, then refur- bished and utilized again.
Initial flight testing of the Dyna-Soar had the vehicle dropped from a modified B-52C, 53-0399, carrier aircraft to test atmospheric handling qualities and landing techniques. The USAF selected Ed wards AFB, CA, and White Sands Missile Range, NM, due to their natural runway surfaces. (AFTC History Office)
The initial phase of the X-20 flight test program had the vehicle dropped from high altitudes from a B-52C mothership to test atmospheric aerodynamic handing of the vehicle, as well as develop landing techniques at Edwards AFB, CA. The second phase of testing involved sending the X-20 on unmanned and manned orbital spaceflight test mis- sions powered by a Titan III rocket booster which left a large gap in the standard progression of flight testing. The Convair Division of General Dynam- ics proposed making suborbital test flights using a Little Joe II booster.
The Little Joe II was a clustered, solid-propellant rocket booster designed as unguided and controllable versions. The vehicle could accommodate one to seven, 40-inch diameter, 100,000-lb thrust, Aerojet Algol 1D solid rocket mo- tors. With minor modifications the im proved launch vehicle (IPLV) could ac commodate the more advanced 44-inch diameter Algol IIA motors.
Little Joe II had the reputation as a reliable work- horse of the early manned space program, testing Mercury and Apollo escape and recovery systems from various launch locations. The Little Joe II booster was a versatile rocket with capabilities not found on many systems of the day and could be adapted and configured for several different flight profiles.
This detailed dimensional drawing shows some of the modifications required for the Little Joe il booster in order to carry the Dyna-Soar test vehicle. In addition to the upper adapter fairing, the booster required larger aerodynamic stabilizing fins to compensate for the larger payload. (Convair)
Convair proposed making test flights of the Dyna- Soar/Little Joe II combination on an overland range between Edwards AFB, CA and the White Sands Missile Range in New Mexico. Launching from Edwards AFB provided a lakebed in case of an aborted launch . and emergency landing. Range instrumentation was already in place at both sites, keeping the range support cost to a minimum.
Two different versions of the modified Little Joe II booster
The Dyna-Soar test vehicle would be mounted atop the Little Joe II booster with a two-part transition fairing, gloved over the X-20 to minimize drag and would be jettisoned prior to separation. This variation of the Little Joe II booster required movable aerodynamic fins, larger than those used on standard Little Joe II launches.

Utilizing a standard Little Joe II booster, the X-20 could be propelled to a maximum speed of 10,000 fps (approximately 6,800 mph) at an altitude near 170,000 feet. With the improved Little Joe II launch vehi- cle, those figures would rise to a speed of 15,000 fps (approximately 10,200 mph) and an altitude near 200,000 feet. The entire flight covered approximately 582 nautical miles, with the booster impacting the desert floor just over halfway through the flight. The Dyna-Soar test vehicle would experience considerable aerodynamic heating during the reentry phase with the final landing on the alkali flats of the White Sands Missile Range.
The Dyna-Soar suborbital program required a minimum of five test flights: two unmanned flights utilizing the existing automatic guidance, and three manned flights. Convair projected the total price of the five-flight test program at $12.2 million, considerably less than the projected $18 million per flight for a Titan III booster (figures are in FY 1965 dollars)."
