20 May 1969: The Apollo 11 Saturn V (SA-506) “stack” was rolled out of the Vehicle Assembly Building aboard a Mobile Launch Platform, carried by a Crawler-Transporter, and moved to Launch Complex 39A. The rocket would be launched for the Moon at 13:32:00 UTC, 16 July 1969.

The two Crawler-Transporters are the world’s largest self-propelled land vehicles. They were designed and built by Marion Power Shovel Company, Marion, Ohio, and were assembled on Merritt Island. (The Crawlerway connected the island to mainland Florida, so that it now forms a peninsula.) They are 131 feet (39.9 meters) long and 113 feet  (34.4 meters) wide. The height is adjustable from 20 feet (6.1 meters) to 26 feet (7.9 meters). The load deck is 90 feet × 90 feet (27.4 × 27.4 meters). The transporters weigh 2,721 metric tons (3,000 tons).

The Crawler-Transporters were powered by two 10,687.7-cubic-inch-displacement (175.1 liters) liquid-cooled, turbosupercharged, American Locomotive Company (ALCO) V-16 251C 45° sixteen-cylinder 4-cycle diesel engines. This engine produced 2,750 horsepower. The engines drive four 1,000 kilowatt electric generators. These in turn supply electricity to sixteen 375 horsepower traction motors.

Two 1,065 horsepower White-Superior eight-cylinder diesel engines provide electrical and hydraulic power to operate the crawlers’ systems. The hydraulic system operates at 5,200 p.s.i.

The maximum loaded speed is 0.9 miles per hour (1.4 kilometers per hour).

Since the time of the Apollo and Space Shuttle Programs, the Crawler-Transporters have been upgraded to handle the Space Launch System (SLS) heavy-lift rockets. The original ALCO locomotive engines have been replaced by two Cummins QSK95 16-cylinder diesel/C3000-series 1,500 kW power generation units. The new engine displaces 5,797 cubic inches and produces a maximum 4,200 horsepower at 1,200 r.p.m. The QSK95 has 46% less displacement than the old ALCO, weighs 39% less, but produces 57% more horsepower. The generators also double the electrical output.

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 (110.642 meters) tall. The first and second stages were 33 feet (10.058 meters) in diameter. Fully loaded and fueled the rocket weighed 6,200,000 pounds (2,948,350 kilograms). It could lift a payload of 260,000 pounds (117,934 kilograms) to Low Earth Orbit.

The 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 and had an empty weight of 290,000 pounds (131,542 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 5,100,000 pounds (2,131,322 kilograms). It was propelled by five Rocketdyne F-1 engines, producing 1,522,000 pounds of thrust, each, for a total of 7,610,000 pounds of thrust at Sea Level. These engines were ignited seven seconds prior to lift off and the outer four burned for 168 seconds. The center engine was shut down after 142 seconds to reduce the rate of acceleration. The F-1 engines were built by the Rocketdyne Division of North American Aviation at Canoga Park, California.

The S-II second stage was built by North American Aviation at Seal Beach, California. It was 81 feet, 7 inches (24.87 meters) tall and had the same diameter as the first stage. The second stage weighed 80,000 pounds (36,000 kilograms) empty and 1,060,000 pounds loaded. 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 McDonnell Douglas Astronautics 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). It had a dry weight of 23,000 pounds (10,000 kilograms) and fully fueled weighed 262,000 pounds. The third stage had one J-2 engine and also used liquid hydrogen and liquid oxygen for propellant. The S-IVB wou 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.

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

Colonel Robin Olds, United States Air Force

20 May 1967: Colonel Robin Olds, USAF, commanding officer of the 8th Tactical Fighter Wing based at Ubon Rachitani Royal Thai Air Force Base, and Weapons System Officer 1st Lieutenant Stephen B. Croker, destroyed two Vietnam People’s Air Force MiG-17 fighters with AIM-7 Sparrow radar-guided and AIM-9 Sidewinder heat-seeking air-to-air missiles while flying McDonnell F-4C-24-MC Phantom II, serial number 64-0829, named SCAT XXVII.

An official U.S. Air Force history publication describes the air battle:

Two other MiG-17s became the victims of Col. Robin Olds and his pilot, 1st. Lt. Stephen B. Croker. [Note: at this point in time, the WSOs of USAF F-4Cs were fully-rated pilots.—TDiA] These were aerial victories three and four for Olds, making him the leading MiG-killer at that time in Southeast Asia. An ace from World War II, the 8th TFW commander was battle-tested and experienced. Olds termed the events of 20 May “quite a remarkable air battle.” According to his account:

F-105s were bombing along the northeast railroad; we were in escort position, coming in from the Gulf of Tonkin. We just cleared the last of the low hills lying north of Haiphong, in an east-west direction, when about 10 or 12 MiG-17s came in low from the left and, I believe, from the right. They tried to attack the F-105s before they got to the target.

We engaged MiG-17s at approximately 15 miles short of the target. The ensuing battle was an exact replica of the dogfights in World War II.

Our flights of F-4s piled into the MiGs like a sledge hammer, and for about a minute and a half or two minutes that was the most confused, vicious dogfight I have ever been in. There were eight F-4Cs, twelve MiG-17s, and one odd flight of F-105s on their way out from the target, who flashed through the battle area.

Quite frankly, there was not only danger from the guns of the MiGs, but the ever-present danger of a collision to contend with. We went round and round that day with the battles lasting 12 to 14 minutes, which is a long time. This particular day we found that the MiGs went into a defensive battle down low, about 500 to 1,000 feet. In the middle of this circle, there were two or three MiGs circling about a hundred feet—sort of in figure-eight patterns. The MiGs were in small groups of two, three, and sometimes four in a very wide circle. Each time we went in to engage one of these groups, a group from the opposite side would go full power, pull across the circle, and be in firing position on our tails almost before we could get into firing position with our missiles. This was very distressing, to say the least.

The first MiG I lined up was in a gentle left turn, range about 7,000 feet. My pilot achieved a boresight lock-on, went full system, narrow gate, interlocks in. One of the two Sparrows fired in ripple guided true and exploded near the MiG. My pilot saw the MiG erupt in flame and go down to the left.

We attacked again, trying to break up that defensive wheel. Finally, once again, fuel considerations necessitated departure. As I left the area by myself, I saw that lone MiG still circling and so I ran out about ten miles and said that even if I ran out of fuel, he is going to know he was in a fight. I got down on the deck, about 50 feet, and headed right for him. I don’t think he saw me for quite a while. But when he did, he went mad, twisting, turning, dodging and trying to get away. I kept my speed down so I wouldn’t overrun him and I stayed behind him. I knew he was either going to hit that ridge up ahead or pop over the ridge to save himself. The minute he popped over I was going to get him with a Sidewinder.

I fired one AIM-9 which did not track and the MiG pulled up over the ridge, turned left and gave me a dead astern shot. I obtained a good growl. I fired from about 25 to 50 feet off the grass and he was clear of the ridge by only another 50 to 100 feet when the Sidewinder caught him.

The missile tracked and exploded 5 to 10 feet to the right side of the aft fuselage. The MiG spewed pieces and broke hard left and down from about 200 feet. I overshot and lost sight of him.

I was quite out of fuel and all out of missiles and pretty deep in enemy territory all by myself, so it was high time to leave. We learned quite a bit from this fight. We learned you don’t pile into these fellows with eight airplanes all at once. You are only a detriment to yourself.

North American Aviation P-86A-1-NA Sabre 47-605, the first production aircraft. (U.S. Air Force)

20 May 1948: The first production North American Aviation, Inc., P-86A-1-NA, 47-605, made its first flight.

The P-86A-1-NA was very similar to the three XP-86 prototypes. As an operational fighter, its empty weight increased 347 pounds to 10,077 pounds. The Chevrolet J35-C-3 and Allison J35-A-5 engines were replaced with a more powerful General Electric J47-GE-1. The fighter’s maximum speed increased 74 miles per hour to 673 miles per hour at Sea Level.

The P-86 was unlike any airplane before it. (The designation was changed to F-86 the following month.) It was the first airplane produced with a swept wing. After analyzing World War II test data for the Messerschmitt Me 262, North American’s engineers designed a wing with a 35° degree sweepback to its leading edge. The wing sweep allowed high speed shock waves to form without stalling the entire wing. The wing tapered toward the tips, and its thickness also decreased from the root to the tip. In order to create a very strong but very thin wing, it was built with a two-layered aluminum skin, instead of ribs and spars, with each layer separated by “hat” sections. The thickness of the skin panels also tapered to decrease weight.

The wing  incorporated leading edge “slats” which were airfoil sections that automatically extended below 290 knots, smoothing the air flow over the wing’s upper surface and creating more lift at slow speeds. Above that speed, aerodynamic forces closed the slats, decreasing drag and allowing for higher speeds. Effectively, the wing could change its shape in flight.

Like the XP-86, the P-86A was 37 feet, 6.5 inches (11.443 meters) long with a wingspan of 37 feet, 1.4 inches (11.313 meters) and overall height of 14 feet, 8.9 inches (4.493 meters). The empty weight was 10,077 pounds (4,571 kilograms), gross weight, 14,050 pounds (6,373 kilograms) and maximum takeoff weight was 15,876 pounds (7,201 kilograms).

The J47-GE-1 was an axial-flow turbojet with a 12-stage compressor, 8 combustion chambers, and single stage turbine. It had a normal power rating of 4,320 pounds of thrust (19.216 kilonewtons) at 7,370 r.p.m.; and military power, 5,200 pounds (23.131 kilonewtons) at 7,950 r.p.m. (30-minute limit).

The P-86A had an initial rate of climb 7,470 feet per minute (37.95 meters per second) and could reach 40,000 feet (12,192 meters) in 10 minutes, 24 seconds. Its service ceiling was 48,000 feet (14,630 meters).

The Sabre was armed with six Browning AN-M3 .50-caliber aircraft machine guns placed in the nose, with three on either side of the engine intake. These were lighter and had a higher rate of fire than the World War II AN-M2 machine guns. Ammunition containers had a capacity of 300 rounds, but normally they carried 267 rounds per gun. Early aircraft had small doors covering each gun port. They opened in 0.05 seconds but were difficult to keep properly adjusted, so they were soon deleted.

The airplane could also be armed with two bombs and up to sixteen 5-inch (12.7 centimeter) High Velocity Aerial Rockets (HVAR) on underwing hardpoints.

North American Aviation built thirty-three P-86A-1-NAs. The U.S. Air Force ordered 190 F-86Bs, but these were cancelled in favor of the F-86A-5-NA.

The F-86A became operational with the 1st Fighter Group at March Air Force Base, near Riverside, California. In February 1949, a contest was held within the group to select a name for the new fighter. “Sabre” was chosen.

20 May 1941: North American Aviation, Inc., test pilot Robert Creed Chilton took the first XP-51 for its maiden flight at Mines Field, Los Angeles, California. The XP-51 was the fourth production Mustang Mk.I built for the Royal Air Force, (North American serial number 73-3101) and assigned registration number AG348.

The Mustang was reassigned to the U.S. Army Air Force, designated as XP-51, serial number 41-038, and sent to Wright Field, Dayton, Ohio, for evaluation.

The Mustang Mk.I (NAA Model NA-73) was a single-place, single engine fighter primarily of metal construction with fabric control surfaces. It was 32 feet, 3 inches (9.830 meters) long with a wingspan of 37 feet, 5/16-inches (11.373 meters) and height of 12 feet, 2½ inches (3.721 meters). The airplane’s empty weight was 6,280 pounds (2,849 kilograms) and loaded weight was 8,400 pounds (3,810 kilograms).

The Mustang was powered by a liquid-cooled, supercharged, 1,710.597-cubic-inch-displacement (28.032 liter) Allison Engineering Company V-1710-F3R (V-1710-39) single overhead cam (SOHC) 60° V-12 engine with a compression ratio of 6.65:1. The -F3R had a Normal Power rating of 880 horsepower at 2,600 r.p.m., at Sea Level, and 1,000 horsepower at 2,600 r.p.m. at 11,000 feet (3,353 meters). It had a Takeoff and Military Power rating of 1,150 horsepower at 3,000 r.p.m., to 11,800 feet (3,597 meters). The engine turned a 10 foot, 9 inch (3.277 meter) diameter three-bladed Curtiss Electric constant-speed propeller through a 2.00:1 gear reduction. The V-1710-F3R was 7 feet, 4.38 inches (2.245 meters) long, 3 feet, 0.54 inches (0.928 meters) high, and 2 feet, 5.29 (0.744 meters) wide. It weighed 1,310 pounds (594 kilograms).

The Mustang Mk.I had a maximum speed of 382 miles per hour (615 kilometers per hour) at 13,700 feet (4,176 meters), the Allison’s critical altitude, and cruise speed of 300 miles per hour (483 kilometers per hour). The service ceiling was 30,800 feet (9,388 meters) and range was 750 miles (1,207 kilometers).

The Mk.I was 30 m.p.h. faster than its contemporary, the Curtiss P-40 Warhawk, though both used the same engine. Below 15,000 feet, the Mustang was also 30–35 m.p.h faster than a Supermarine Spitfire, which had a more powerful Roll-Royce Merlin V-12.

The XP-51 would be developed into the legendary P-51 Mustang. In production from 1941 to 1945, a total of 16,766 Mustangs of all variants were built.

Robert Creed Chilton was born 6 February 1912 at Eugene, Oregon, the third of five children of Leo Wesley Chilton, a physician, and Edith Gertrude Gray. He attended Boise High School in Idaho, graduating in 1931. Chilton participated in football, track and basketball, and also competed in the state music contest. After high school, Chilton attended the University of Oregon where he was a member of the Sigma Chi fraternity (ΣΧ). He was also a member of the Reserve Officers Training Corps (ROTC).

Bob Chilton enlisted as an Aviation Cadet in the U.S. Army Air Corps, 25 June 1937. He was trained as a fighter pilot at Randolph Field and Kelly Field in Texas, and was commissioned as a Second Lieutenant in 1938. Lieutenant Chilton was assigned to fly the Curtiss P-36 Hawk with the 79th Pursuit Squadron, 20th Pursuit Group, at Barksdale Field, Louisiana. Because of a medical condition, he was released from active duty, 1 April 1939.

At some time prior to 1940, Bob Chilton, married his first wife, Catherine. They lived in Santa Maria, California, where he worked as a pilot at the local airport.

In January 1941, Chilton went to work as a production test pilot for North American Aviation, Inc., Inglewood, California. After just a few months, he was assigned to the NA-73X.

Chilton married his second wife, Betty W. Shoemaker, 15 November 1951.

On 10 April 1952, Bob Chilton returned to active duty with the U.S. Air Force, with the rank of lieutenant colonel. He served as Chief of the Republic F-84 and F-105 Weapons System Project Office, Air Material Command, at Wright-Patterson Air Force Base, Dayton, Ohio, until 9 March 1957.

From 1958, Chilton was a vice president for Horkey-Moore Associates, an engineering research and development company in Torrance, California, founded by former North American aerodynamacist Edward J. Horkey. In 1961, he followed Horkey to the Space Equipment Corporation, parent company of Thompson Industries and Kerr Products, also located in Torrance. Chilton served as corporate secretary and contracts administrator.

Chilton married his third wife, Wilhelmina E. Redding (Billie E. Johnson) at Los Angeles, 26 July 1964. They divorced in 1972.

In 1965, Bob Chilton returned to North American Aviation as a flight test program manager. He retired in 1977.

Robert Creed Chilton died at Eugene, Oregon, 31 December 1994, at the age of 82 years.

Amelia Earhart with her Lockheed Electra 10E, NR16020.

Leg 1: After her Lockheed Electra 10E Special, NR16020, was repaired by Lockheed following a takeoff accident at Wheeler Field, Oahu, in March, Amelia Earhart repositioned it to Oakland Municipal Airport to begin her second attempt to fly around the world. Because of changing weather patterns since the earlier attempt, this time her route will be eastward.

On 20 May 1937, without any public notice, Earhart and her navigator, Captain Frederick J. Noonan, left Oakland, California, on the first leg of the trip: 283 nautical miles (325 miles (523 kilometers) to Union Air Terminal, Burbank, California (now, Hollywood Burbank Airport—BUR), where the airplane was manufactured and repaired. They arrived at about 6:00 p.m. and remained there over night.

“The rebuilt Electra came out of the Lockheed plant on May 19. Two days later we flew it to Oakland. . .  As that time we had made no announcement of my decision to reverse the direction of the flight. It seemed sensible to slip away as quietly as we could. While I was actually heading for Miami, with hope of keeping on from there eastward, technically the journey from Burbank across the country was a shake-down flight. If difficulties developed we would bring the ship back to the Lockheed plant for further adjustments.”
