22 March 1956: While carrying the U.S. Navy’s Douglas D-558-II Skyrocket, problems developed aboard both the research rocketplane and the “mothership.” The modified four-engine heavy bomber, a U.S. Air Force Boeing B-29-95-BW Superfortress (which had been transferred to the U.S. Navy and redesignated P2B-1S Superfortress), had a runaway propeller on the Number 4 engine, outboard on the right wing. The propeller broke apart from excessive rotational speed, slicing through the Number 3 engine, the fuselage, and striking the Number 2 engine.

NACA research test pilot John Barron (“Jack”) MacKay, in the cockpit of the Skyrocket, had called “No drop!” because of problems with the rocketplane, but he was jettisoned so that the mothership could maintain flight and make an emergency landing.
McKay dumped the Skyrocket’s propellants and glided to the lake bed.

“Each rocket-plane pilot had worked out, in conjunction with the pilot of the mother ship, a procedure to follow if any emergency developed in either plane. Jack McKay, who had developed into a very able test pilot, and I had agreed with Butchart that if something went wrong after either of us had entered the cockpit of the Skyrocket and had closed the canopy, he would immediately jettison the rocket plane, leaving the rocket-plane pilot to look after his own hide. As a matter of fact, McKay and Butchart later ran into such an emergency. One day something went haywire in a propeller on the B-29 mother plane. As agreed, Butchart instantly cut loose the Skyrocket. A split second later the B-29 prop tore loose and cartwheeled through the space the Skyrocket had just vacated. McKay landed without difficulty; but had Butchart not cut the parasite plane loose, the prop would have ripped into its fuel tanks, causing an explosion that would have killed everyone, including McKay.”

Gemini VIII lifts off from Launch Complex 19, Cape Kennedy Air Force Station, 16:41:02 UTC, 16 March 1966. (NASA)
16 March 1966: At 16:41:02.389 UTC (12:41:02 p.m. Eastern Standard Time), forty years to the day after the launch of Dr. Robert Goddard’s first liquid-fueled rocket, Gemini VIII, with command pilot Neil Alden Armstrong and pilot David Randolph Scott, lifted off from Launch Complex 19 at the Cape Kennedy Air Force Station, Cape Kennedy, Florida, aboard a Titan II GLV booster. Their mission was to rendezvous and dock with an Agena Target Vehicle launched earlier aboard an Atlas rocket.
Gemini VIII entered a 86.3 × 146.7 nautical mile (99.3 × 168.8 statute miles/160 × 271.7 kilometers) elliptical orbit. The spacecraft was traveling at 17,549 miles per hour (28,242 kilometers per hour).

The docking, the first ever of two vehicles in Earth orbit, was successful, however after about 27 minutes the combined vehicles begin rolling uncontrollably. The Gemini capsule separated from the Agena, and for a few minutes all seemed normal. But the rolling started again, reaching as high as 60 r.p.m.
The astronauts were in grave danger. Armstrong succeeded in stopping the roll but the Gemini’s attitude control fuel was dangerously low.

The pilots’ report reads:
Shortly after sending encoder command 041 (recorder ON), roll and yaw rates were observed to be developing. No visual or audible evidence of spacecraft thruster firing was noted, and the divergence was attributed to the GATV.
Commands were sent to de-energize the GATV ACS, geocentric rate, and horizon sensors, and the spacecraft Orbital Attitude and Maneuver System (OAMS) was activated.
The rates were reduced to near zero, but began to increase upon release of the hand controller. The ACS was commanded on to determine if GATV thruster action would help reduce the angular rates. No improvement was noted and the ACS was again commanded off. Plumes from a GATV pitch thruster were visually observed, however, during a period when the ACS was thought to be inactivated.
After a period of relatively stable operation, the rates once again began to increase. The spacecraft was switched to secondary bias power, secondary logics, and secondary drivers in an attempt to eliminate possible spacecraft control-system discrepancies. No improvement being observed, a conventional troubleshooting approach with the OAMS completely de-energized was attempted, but subsequently abandoned because of the existing rates.
An undocking was performed when the rates were determined to be low enough to precluded any recontact problems. Approximately a 3 ft/sec velocity change was used to effect separation of the two vehicles.
Angular rates continued to rise, verifying a spacecraft control-system problem. The hand controller appeared to be inactive. The Reentry Control System (RCS) was armed and, after trying ACME-DIRECT and then turning off all OAMS control switches and circuit breakers, was found to be operative in DIRECT-DIRECT. Angular rates were reduced to small values with the RCS B-ring. Inspection of the OAMS revealed that the no. 8 thruster had failed to open. Some open Attitude Control and Maneuver Electronics (ACME) circuit breakers probably accounted for the inoperative hand controller noted earlier. All yaw thrusters other than number 8 were inoperative. Pitch and roll control were maintained using the pitch thrusters. . .
All four retrorockets fired on time. . . .

The mission was aborted and the capsule returned to Earth after 10 hours, 41 minutes, 26.0 seconds, landing in the Pacific Ocean at N. 25° 12′, E. 136° 05′. U.S. Air Force pararescue jumpers (“PJs”) parachuted from a Douglas C-54 transport and attached a flotation collar to the Gemini capsule. The astronauts were recovered by the Gearing-class destroyer USS Leonard F. Mason (DD-852), about three hours later..

The two-man Gemini spacecraft was built by the McDonnell Aircraft Corporation of St. Louis, Missouri, the same company that built the earlier Mercury space capsule. The spacecraft consisted of a series of cone-shaped segments forming a reentry module and an adapter section. It had an overall length of 18 feet, 9.84 inches (5.736 meters) and a maximum diameter of 10 feet, 0.00 inches (3.048 meters) at the base of the equipment section. The reentry module was 11 feet (3.353 meters) long with a maximum diameter of 7 feet, 6.00 inches (2.347 meters). The Gemini re-entry heat shield was a spherical section with a radius of 12 feet, 0.00 inches (3.658 meters). The weight of the Gemini spacecraft varied from ship to ship. Gemini VIII weighed 8,351.31 pounds (3,788.09 kilograms) at launch. Spacecraft 8 was shipped from the St. Louis factory to Cape Kennedy on 2 January 1966.

The Titan II GLV was a “man-rated” variant of the Martin SM-68B intercontinental ballistic missile. It was assembled at Martin’s Middle River, Maryland plant so as not to interfere with the production of the ICBM at Denver, Colorado. Twelve GLVs were ordered by the Air Force for the Gemini Program.
Titan II GLV, (NASA Mission Report, Figure 3-1, at Page 3–23)
The Titan II GLV was a two-stage, liquid-fueled rocket. The first stage was 70 feet, 2.31 inches (21.395 meters) long with a diameter of 10 feet (3.048 meters). It was powered by an Aerojet Engineering Corporation LR87-7 engine which combined two combustion chambers and exhaust nozzles with a single turbopump unit. The engine was fueled by Aerozine 50, a hypergolic 51/47/2 blend of hydrazine, unsymetrical-dimethyl hydrazine, and water. Ignition occurred spontaneously as the components were combined in the combustion chambers. The LR87-7 produced approximately 430,000 pounds of thrust (1,912.74 kilonewtons). It was not throttled and could not be shut down and restarted. Post flight analysis indicated that the first stage engine of GLV-8 had produced an average of 461,080 pounds of thrust ( kilonewtons).
The second stage was 25 feet, 6.375 inches (7.782 meters) long, with the same diameter, and used an Aerojet LR91 engine which produced approximately 100,000 pounds of thrust (444.82 kilonewtons), also burning Aerozine 50. GLV-7’s LR91 produced an average of 102,735 pounds of thrust ( kilonewtons).
The Gemini/Titan II GLV VIII combination had a total height of 107 feet, 7.33 inches (32.795 meters) and weighed 345,359 pounds (156,652 kilograms) at ignition.

19–20 February 1979: Professor Neil Alden Armstrong of the University of Cincinnati College of Engineering, a member of the Board of Directors of Gates Learjet Corporation, former United States Navy fighter pilot, NACA/NASA research test pilot, Gemini and Apollo astronaut, and The First Man To Set Foot On The Moon, set five Fédération Aéronautique Internationale (FAI) and National Aeronautics Association class records for time to climb to an altitude and altitude while flying the prototype Learjet 28, serial number 28-001.
Professor Neil Armstrong and co-pilot Peter Reynolds in the cockpit of the record-setting Learjet 28.
Armstrong, with Learjet program test pilot Peter Reynolds as co-pilot, and with NAA observer Don Berliner aboard, flew the Learjet 28 to 15,000 meters (49,212.598 feet) in 12 minutes, 27 seconds over Kittyhawk, North Carolina, on 19 February.¹
On the same day, during a flight from Wichita, Kansas, to Elizabeth City, North Carolina, Armstrong flew the Learjet to 15,584.6 meters (51,130.577 feet), setting records for altitude, and for sustained altitude in horizontal flight.² ³
The following day, 20 February 1979, flying from Elizabeth City, North Carolina, to Florence, Kentucky, Armstrong again set altitude and sustained altitude in horizontal flight, in a different class, by taking the Learjet to 15,585 meters (51,131.89 feet).⁴ ⁵

The Learjet 28 was a development of the Learjet 25 twin-engine business jet. It is operated by two pilots and can carry 8 passengers. The Model 28 used a new wing design. It was the first civil aircraft to be certified with winglets. The prototype first flew 24 August 1977, and it received certification from the Federal Aviation Administration 29 July 1979.
The Learjet 28 is 47 feet, 7.5 inches (14.516 meters) long with a wingspan of 43 feet, 9½ inches (13.348 meters) and overall height of 12 feet, 3 inches (3.734 meters). The wing area is 264.5 square feet (24.6 square meters) It has an empty weight of 7,895 pounds (3,581 kilograms) and maximum takeoff weight of 15,000 pounds (6,804 kilograms).
The Learjet 28 is powered by two General Electric CJ610-8A turbojet engines. This is a single-shaft axial-flow turbojet, developed from the military J85. It has an 8-stage compressor section and 2-stage turbine. The CJ610-8A is rated at 2,850 pounds of thrust (12.68 kilonewtons) at 16,500 r.p.m., and 2,950 pounds (13.12 kilonewtons) at Sea Level, for takeoff (five minute limit).
The business jet has a cruise speed of 464 knots (534 miles per hour (859 kilometers per hour) at 51,000 feet (15,544.8 meters). The Learjet 28 has a maximum range of 1,370 nautical miles (1,577 statute miles/2,537 kilometers). The airplane’s maximum operating altitude is 51,000 feet (15,545 meters), the same as the record altitude. It can reach that altitude in less than 35 minutes.
The aircraft was limited by its older technology turbojet engines, and only five Learjet 28s were built.
The first Learjet 28, serial number 28-001, has been re-registered several times. At the time of its FAI record-setting flights, it carried FAA registration N9RS. Later it was registered as N3AS. The most recent information shows it currently registered as N128LR.
The record-setting Learjet 28 is in the collection of the Armstrong Air & Space Museum, Wapakoneta, Ohio.
