On Wednesday morning, 16 July 1969, the Apollo 11/Saturn V launch vehicle, AS-506), stood on the pad at Launch Complex 39A, Kennedy Space Center, Cape Canaveral, Florida. On board were Neil Alden Armstrong, Mission Commander; Michael Collins, Command Module Pilot; and Edwin E. Aldrin, Jr., Lunar Module Pilot. Their destination was Mare Tranquillitatis, The Moon.

The cryogenic liquid oxygen in the rocket’s propellant tanks cooled the humid Florida air to the point that frost formed on the tanks’ skin.

The mission was on schedule. At T – 6.1 seconds (13:31:53.9 UTC) the first of the five F-1 engines ignited, followed in quick succession by the others. When the engines had reached full thrust, the pad’s hold-down arms were released. First Motion—10.47 m/s² (34.35 ft/s²)—1.07 gs , was detected at T + 0.3 seconds (13:32:00.3 UTC, 9:32:00.3 a.m., Eastern Daylight Time). The umbilical was released at T + 0.6 seconds. The Saturn V cleared the gantry tower and rolled onto its programmed course.

The Saturn V rocket was a three-stage, liquid-fueled heavy launch vehicle. Fully assembled with the Apollo Command and Service Module, it stood 363 feet, 0.15 inches (110.64621 meters) tall, from the tip of the escape tower to the bottom of the F-1 engines. Fully loaded and fueled, AS-506 weighed  6,477,875 pounds (2,938,315 kilograms).

The Saturn V first stage was designated S-IC. It was designed to lift the entire rocket to an altitude of 220,000 feet (67,056 meters) and accelerate to a speed of more than 5,100 miles per hour (8,280 kilometers per hour). The S-IC stage was built by Boeing at the Michoud Assembly Facility, New Orleans, Louisiana. It was 138 feet (42.062 meters) tall, 33 feet, 1.2 inches (10.089 meters) in diameter, and had an empty weight of 287,531 pounds (130,422 kilograms). Fully fueled with 203,400 gallons (770,000 liters) of RP-1 and 318,065 gallons (1,204,000 liters) of liquid oxygen, the stage weighed 5,023,648 pounds (2,131,322 kilograms). It was propelled by five Rocketdyne F-1 engines, which were built by the Rocketdyne Division of North American Aviation, Inc., at Canoga Park, California.

The AS-506 S-IC stage’s five F-1 engines  produced 7,552,000 pounds of thrust (33,593 kilonewtons). According to the post-mission flight evaluation report, “The F-1 engines performance levels during the AS-506 flight showed the smallest deviations of any S-IC Flight.” The center engine shut down at T + 135.20 to limit the rocket’s acceleration, and the outer four were shut down at T + 161.63 seconds.

The S-II second stage was built by North American Aviation, Inc., at Seal Beach, California. It was 81 feet, 7 inches (24.87 meters) tall and had the same diameter as the first stage. The AS-506 second stage weighed 79,714 pounds (36,158 kilograms), dry, and 1,058,140 pounds (479,964 kilograms), fueled. The propellant for the S-II was liquid hydrogen and liquid oxygen. The stage was powered by five Rocketdyne J-2 engines, also built at Canoga Park. Each engine produced 232,250 pounds of thrust, and combined, 1,161,250 pounds of thrust.

The Saturn V third stage was designated S-IVB. It was built by Douglas Aircraft Company at Huntington Beach, California. The S-IVB was 58 feet, 7 inches (17.86 meters) tall with a diameter of 21 feet, 8 inches (6.604 meters). The AS-506 S-IVB third stage had a dry weight of 24,852 pounds (11,273 kilograms) and fully fueled, it weighed 262,613 pounds (119,119 kilograms). The third stage had one J-2 engine which also used liquid hydrogen and liquid oxygen for propellant. At the first burn, the J-2 produced 202,603 pounds of thrust (901.223 kilonewtons). The S-IVB would place the Command and Service Module into Low Earth Orbit, then, when all was ready, the J-2 would be restarted for the Trans Lunar Injection. At this second burn, it produced 201,061 pounds  of thrust (894.364 kilonewtons).

The Apollo Command/Service Module was built by the Space and Information Systems Division of North American Aviation, Inc., at Downey, California. The Apollo 11 Command and Service Module, CSM-107, weighed 109,646 pounds (49,735 kilograms).

The SPS engine was an AJ10-137, built by Aerojet General Corporation of Azusa, California. It burned a hypergolic fuel combination of Aerozine 50 and nitrogen tetraoxide, producing 20,500 pounds of thrust (91.19 kilonewtons). It was designed for a 750 second burn, or 50 restarts during a flight.

The Apollo Lunar Module was built by Grumman Aerospace Corporation to carry two astronauts from lunar orbit to the surface, and return. There was a descent stage and ascent stage. The LM was intended only for operation in the vacuum of space, and was expended after use.

The LM was 23 feet, 1 inches (7.036 meters) high with a maximum landing gear spread of 31 feet (9.449 meters). It weighed 33,500 pounds (15,195 kilograms). The spacecraft was designed to support the crew for 48 hours, though in later missions, this was extended to 75 hours.

The Descent Stage was powered by a single TRW LM Descent Engine. The LMDE used hypergoloc fuel and was throttleable. It produced from 1,050 pounds of thrust (4.67 kilonewtons) to 10,125 pounds (45.04 kilonewtons). The Ascent Stage was powered by a Bell Aerospace Lunar Module Ascent Engine. This also used hypergolic fuels. It produced 3,500 pounds of thrust (15.57 kilonewtons).

Eighteen Saturn V rockets were built. They were the most powerful machines ever built by man.

22 March 1956

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.”

Always Another Dawn: The Story of a Rocket Test Pilot, by A. Scott Crossfield and Clay Blair, Jr., The World Publishing Company, Cleveland and New York, 1960, Chapter 21 at Pages 201–202.

The Superfortress pilots, Stanley Paul Butchart and Neil Alden Armstrong, landed the plane safely on the lake bed at Edwards Air Force Base.

Neil Armstrong would land on The Moon 13 years later.

19–20 February 1979: Professor Neil A. Armstrong of the University of Cincinnati College of Engineering, 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, March 1979.
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 at Kittyhawk, North Carolina on 19 February. On the same day, during a flight from Wichita, Kansas, to Elizabeth City, North Caroline, Armstrong flew the Learjet to 15,584.6 meters (51,130.577 feet), setting records for altitude and for sustained altitude in horizontal flight.

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).

The Learjet 28 was a development of the Learjet 25 twin-engine business jet. It was operated by two pilots and could carry 6–8 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 inches (14.503 meters) long with a wingspan of 43 feet, 10 inches (13.360 meters) and overall height of 12 feet, 3 inches (3.734 meters). It has an empty weight of 8,267 pounds (3,749.9 kilograms) and gross weight of 15,000 pounds (6,803.9 kilograms).

The Learjet 28 is powered by two General Electric CJ610-8A turbojet engines, each  producing 2,850 pounds of thrust at Sea Level, and 2,960 pounds of thrust for takeoff (five minute limit).

The business jet has a cruise speed of 470 miles per hour (756.4 kilometers per hour) at 51,000 feet (15,544.8 meters). Its maximum speed is 549 miles per hour (883.5 kilometers per hour). Maximum range is 1,309 miles (2,106.6 kilometers). The service ceiling is 51,000 feet (15,544.8 meters), the same as the record altitude.

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.

After serving as a naval aviator from 1949 to 1952, Armstrong joined the National Advisory Committee for Aeronautics (NACA) in 1955. His first assignment was with the NACA Lewis Research Center (now NASA Glenn) in Cleveland. Over the next 17 years, he was an engineer, test pilot, astronaut and administrator for NACA and its successor agency, the National Aeronautics and Space Administration (NASA).

As a research pilot at NASA’s Flight Research Center, Edwards, Calif., he was a project pilot on many pioneering high speed aircraft, including the well known, 4000-mph X-15. He has flown over 200 different models of aircraft, including jets, rockets, helicopters and gliders.

Armstrong transferred to astronaut status in 1962. He was assigned as command pilot for the Gemini 8 mission. Gemini 8 was launched on March 16, 1966, and Armstrong performed the first successful docking of two vehicles in space.

As spacecraft commander for Apollo 11, the first manned lunar landing mission, Armstrong gained the distinction of being the first man to land a craft on the moon and first to step on its surface.

Armstrong subsequently held the position of Deputy Associate Administrator for Aeronautics, NASA Headquarters, Washington, D.C. In this position, he was responsible for the coordination and management of overall NASA research and technology work related to aeronautics.

He was Professor of Aerospace Engineering at the University of Cincinnati between 1971-1979. During the years 1982-1992, Armstrong was chairman of Computing Technologies for Aviation, Inc., Charlottesville, Va.

He received a Bachelor of Science Degree in Aeronautical Engineering from Purdue University and a Master of Science in Aerospace Engineering from the University of Southern California. He holds honorary doctorates from a number of universities.

Armstrong is a Fellow of the Society of Experimental Test Pilots and the Royal Aeronautical Society; Honorary Fellow of the American Institute of Aeronautics and Astronautics, and the International Astronautics Federation.

He is a member of the National Academy of Engineering and the Academy of the Kingdom of Morocco. He served as a member of the National Commission on Space (1985-1986), as Vice-Chairman of the Presidential Commission on the Space Shuttle Challenger Accident (1986), and as Chairman of the Presidential Advisory Committee for the Peace Corps (1971-1973).

Armstrong has been decorated by 17 countries. He is the recipient of many special honors, including the Presidential Medal of Freedom; the Congressional Space Medal of Honor; the Explorers Club Medal; the Robert H.
