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 (2,812,273 kilograms).¹ It could lift a payload of 260,000 pounds (117,934 kilograms) to Low Earth Orbit.

The first stage was designated Saturn 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 Saturn 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 Saturn 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.

Edwards Flier Sets Altitude Mark For Jets
By WALT KEESHAN JR. Valley Times Aviation Editor
EL CENTRO — The world’s altitude record for jet planes has been taken to the Antelope Valley by a Navy pilot dressed in a Mars-like suit who flew to the edge of space at 76,828.8 feet above Mojave.
This historic event, announced yesterday at the third annual Naval Air Weapons meet, staged in the Imperial Valley, brought the Distinguished Flying Cross to LCDR George C. Watkins, 37, who gave America the first altitude record it has held in 28 years. The flight was Wednesday.
Flying a F-11-1F Super Tiger, Watkins, of Pasadena, proved that jet airplanes can operate for a brief period of time 14 miles above earth—a period long enough to launch missiles into space.
45-Minute Flight
The actual flight which took Watkins up into the Ozonosphere lasted 45 minutes and covered a distance of 500 miles stretching from Needles to Mojave. He stayed at the record altitude for four seconds.
Watkins flew in a patch like a ballistic missile strapped in his swept-wing fighter, Outside the snug cockpit the temperature was 69 degrees below zero.
The swept-wing fighter shot from the Edwards Air Force Base runway loaded with 6,270 pounds of fuel and raced for Needles, 210 miles to the east.
Making a U-turn 30 miles beyond Needles, Watkins poured on teh speed and dashed toward Edwards with his throttle wide open at 1,260 miles per hour (Mach 1.9) at 40,000 feet.
Cruise Climb
Watkins slowly began to cruise climb, rising 1,500 feet a minute until he had only 400 pounds of fuel left. Rising skyward the afterburner cut off at 65,000 feet and he was on his way.
The altimeter began to spin crazily and all the energy he had built up pushed him up at a rate of 50,000 feet a minute in what pilots call a zoom-glide.
As he eased over the top at 76,828.8 feet, the Super Tiger was only going 100 miles an hour and Watkins was experiencing zero-gravity for more than a minute—an uncomfortable 60 seconds when he became weightless and objects began floating in the cockpit.
Outside the sky was very deep blue. He was the first jet pilot to see this new color. “I hardly had time to look,” Watkins said.
Lands Without Fuel
During the record run he had to hit a five mile square area in the sky so that radar cameras on the ground could officially record his record. He landed without enough fuel to taxi back to the hangar.
The record run was part of “Operation Apollo” now being staged at Edwards. He will try for 84,000 feet probably the first part of next week when the temperature gets down to a minus 79 degrees outside. The colder it is the faster he can go.
The Air Force and the Navy are both interested in this altitude mark because solid missiles could be launched from these sky platforms and fired at tremendously increased distances—maybe put in orbit.
The record Watkins broke was 70,308 feet set by the British last year in a combination jet and rocket powered airplane.

Watkins’ flight was observed by the National Aeronautic Association and certified by the Fédération Aéronautique Internationale (FAI). For his record-setting flight, Lieutenant Commander Watkins was presented the Distinguished Flying Cross by Vice Admiral William F. Davis, Jr., Deputy Chief of Operations for Air.

The F11F-1F Tiger was a higher performance variant of the U.S. Navy F11F single-seat, single-engine swept wing aircraft carrier-based supersonic fighter. The last two regular production F11F-1 Tigers, Bu. Nos. 138646 and 138647 were completed as F11F-2s, with the standard Westinghouse J65-WE-18 turbojet engine replaced by a more powerful General Electric YJ79-GE-3, which produced 9,300 pounds of thrust (41.37 kilonewtons), or 14,350 pounds (63.83 kilonewtons) with afterburner. The air intakes on each side of the fuselage were longer and had a larger area to provide greater airflow for the new engine. After testing, the fuselage was lengthened 1 foot, 1½ inches (0.343 meters) and an upgraded J79 engine installed. The first “Super Tiger” was damaged beyond repair in a takeoff accident and was “expended” as a training aid for fire fighters.
The U.S. Navy determined that the F11F-2 was too heavy for operation aboard carriers and did not place any orders. The designation was changed from F11F-2 to F11F-1F, and later, to F-11B, although the remaining aircraft was no longer flying by that time.
The F11F-1F Tiger is 48 feet, 0.5 inches (14.643 meters) long with a wingspan of 31 feet, 7.5 inches (9.639 meters) and overall height of 13 feet, 10 inches (4.216 meters). The Super Tiger has an empty weight of 16,457 pounds (7,465 kilograms) and maximum takeoff weight of 26,086 pounds (11,832 kilograms).
The General Electric J79 is a single-spool axial-flow afterburning turbojet, which used a 17-stage compressor and 3-stage turbine. The engine is 17 feet, 3.5 inches (5.271 meters) long, 3 feet, 2.3 inches (0.973 meters) in diameter, and weighs 3,325 pounds (1,508 kilograms).
With the YJ79 engine, the F11F-1F has a maximum speed of 836 miles per hour (1,345 kilometers per hour) at Sea Level, 1,325 miles per hour (2,132 kilometers per hour) at 35,000 feet (10,668 meters) and 1,400 miles per hour (2,253 kilometers per hour) at 40,000 feet (12,192 meters). Cruise speed is 580 miles per hour (933 kilometers per hour). It had an initial rate of climb of 8,950 feet per minute (45.5 meters per second) and service ceiling of 50,300 feet (15,331 meters). Range with internal fuel was 1,136 miles (1,828 kilometers).
The Tiger’s armament consisted of four 20 mm Colt Mk 12 autocannon with 125 rounds of ammunition per gun, and four AIM-9 Sidewinder heat-seeking missiles.
The single remaining F11F-1F, Bu. No. 138647, is on static display at the Naval Air Weapons center, China Lake, California.
George Clinton Watkins was born at Alhambra, California, 10 March 1921, the third of seven children of Edward Francis Watkins, a purchasing agent for the Edison Company, and Louise Whipple Ward Watkins. (Mrs. Watkins was a candidate for election to the United States Senate in 1938.) George’s brother, James, would later serve as Chief of Naval Operations.
George was educated at the Army and Navy Academy, Carlsbad, California, and at The Citadel, the Military College of South Carolina, before being appointed to the United States Naval Academy, Annapolis, Maryland. He entered the Academy 3 July 1940. He graduated and was commissioned as an Ensign, United States Navy, 9 June 1943. He was then assigned as a gunnery officer aboard the battleship, USS Pennsylvania (BB-38). Ensign Watkins was promoted to the rank of lieutenant (junior grade), 1 September 1944.
Near the end of the war, Lieutenant (j.g.) Watkins entered pilot training. He graduated and was awarded the gold wings of a Naval Aviator in 1945. He was promoted to the rank of lieutenant, 1 April 1946. His first operational assignment was as pilot of a Grumman TBF Avenger torpedo bomber with VT-41. In 1950 Watkins attended the Navy’s test pilot school at NAS Patuxent River on the Chesapeake Bay, Maryland. Among his classmates were future astronauts John H. Glenn and Alan B. Shepard. Lieutenant Watkins served as a fighter pilot during the Korean War, flying the Grumman F9F-6 with VF-24, aboard USS Yorktown (CVA-10)then returned to duty as a test pilot. On 1 January 1954, he was promoted to lieutenant commander.
George Watkins was the first U.S. Navy pilot to fly higher than 60,000 feet (18,288 meters), and 70,000 feet (21,336 meters). In 1956, he set a speed record of 1,210 miles per hour (1,947.3 kilometers per hour). Lieutenant Commander Watkins was promoted to the rank of commander, 1 March 1958. He was assigned as Commander Air Group 13 in August 1961. On 9 May 1962, Commander Watkins became the first U.S. Navy pilot to have made 1,000 aircraft carrier landings.
Commander Watkins was promoted to the rank of captain, 1 July 1964. Captain Watkins served in planning assignments at the Pentagon, and was an aide to Presidents Kennedy, Johnson and Nixon.

From 14 December 1965 to 12 December 1966, Captain Watkins commanded USS Mars (AFS-1), a combat stores ship. (Experience commanding a deep draft ship was a requirement before serving as captain of an aircraft carrier).
He later served as a technical adviser for the 1970 20th Century Fox/Toei Company movie, “Tora! Tora! Tora!,” about the Japanese attack against Pearl Harbor which brought the United States of America into World War II.
By the time Captain Watkins retired from the Navy in 1973, he had flown more than 200 aircraft types, made 1,418 landings on 37 aircraft carriers, and logged more than 16,000 flight hours. He continued flying after he retired, operating sailplane schools at Santa Monica and Lompoc, California. He had flown more than 21,000 hours during 26,000 flights.
Captain Watkins married Miss Monica Agnes Dobbyn, 20 years his junior, at Virginia Beach, Virginia, 9 June 1979. Mrs. Watkins is the author of Cats Have Angels Too, Angelaura & Company, 1998.
Captain Watkins died 18 September 2005 at the age of 84 years. His ashes were spread at sea from the deck of a United States Navy aircraft carrier.

16 April 1949: At Van Nuys Airport, California, test pilot Tony LeVier and flight test engineer Glenn Fulkerson made the first flight of the Lockheed YF-94 prototype, serial number 48-356. The aircraft was the first jet-powered all-weather interceptor in service with the United States Air Force and was the first production aircraft powered by an afterburning engine.

Two prototypes were built at Lockheed Plant B-9, located on the east side of Van Nuys Airport. Two TF-80C-1-LO (later redesignated T-33A) Shooting Star two-place trainers, 48-356 and 48-373, were modified with the installation of air intercept radar, an electronic fire control system, radar gun sight, four Browning AN-M3 .50-caliber (12.7 × 99 NATO) aircraft machine guns and a more powerful Allison J33-A-33 turbojet engine with water-alcohol injection and afterburner. The rear cockpit was equipped as a radar intercept officer’s station.

It was initially thought that the project would be a very simple, straightforward modification. However, the increased weight of guns and electronics required the installation of a more powerful engine than used in the T-33A. The new engine required that the aft fuselage be lengthened and deepened. Still, early models used approximately 80% of the parts for the F-80C fighter and T-33A trainer. The Air Force ordered the aircraft as the F-94A. Improvements resulted in an F-94B version, but the definitive model was the all-rocket-armed F-94C Starfire.

The Allison J33-A-33 was a single-shaft turbojet engine with a single-stage centrifugal-flow compressor, 14 combustion chambers and, a single-stage axial flow turbine. The engine was rated at 4,600 pounds of thrust (20.46 kilonewtons) and 6,000 pounds (26.69 kilonewtons) with afterburner. The J33-A-33 was 17 feet, 11.0 inches (5.461 meters) long, 4 feet, 1.3 inches (1.252 meters) in diameter and weighed 2,390 pounds (1,084 kilograms).
Originally a P-80C Shooting Star single-place fighter, 48-356 had been modified at Lockheed Plant B-9 in Van Nuys to become the prototype TF-80C two-place jet trainer (the designation was soon changed to T-33A), which first flew 22 March 1948. It was then modified as the prototype YF-94. 48-356 was later modified as the prototype F-94B. It is in the collection of the Air Force Flight Test Museum, Edwards Air Force Base, and is in storage awaiting restoration.
Probably the best-known Lockheed F-94 variant is the all-rocket-armed F-94C Starfire. (Lockheed Martin)

Harriet Quimby, September 1910. (Edmunds Bond/The Boston Globe)
16 April 1912: American aviatrix Harriet Quimby flew across the English Channel in a Blériot XI monoplane. She departed Dover at 5:30 a.m. and crossed a fog-shrouded channel to land at Hardelot-Plage, Pas-de-Calais, 1 hour, 9 minutes later. Her only instruments were a hand-held compass and a watch.
FLIGHT reported:
MISS QUIMBY FLIES THE CHANNEL.
ALTHOUGH Miss Harriet Quimby has made an enviable reputation for herself as a capable pilot in America, her native country, she has not been very well-known on this side of the Atlantic, and no doubt few of our readers who read the announcement in FLIGHT a week or so back that she was coming to Europe, looked for her so soon to make her mark by crossing the Channel. Contrary to what one would expect, the feat was carried through without any fuss or elaborate preparations, and only a few friends, including Mr. Norbet Chereau and his wife and Mrs Griffith, an American friend, knew the attempt was being made and were present at the start. Miss Quimby had ordered a 50-h.p. Gnome-Blériot, which arrived from France on Saturday, and was tested on Sunday by Mr. Hamel. On Tuesday morning, as previously arranged, after Mr. Hamel had taken the machine for a preliminary trial flight, Miss Quimby, who had been staying at Dover under the name of Miss Craig, took her place in the pilot’s seat, and at 5.38 left Deal, rising by a wide circle and steering a course, by the aid of the compass, for Cape Grisnez. Dover Castle was passed at a height of 1,500 feet, and by the time the machine was over the sea, it was at an altitude of about 2,000 feet. Guided solely by compass, Miss Quimby arrived above the Grisnez Lighthouse a little under an hour later, and making her way towards Boulogne she came down at Equihen by a spiral vol plané not far from the Blériot sheds.
To Miss Quimby, therefore belongs the honour of being the first of the fair sex to make the journey, unaccompanied, across the Channel on an aeroplane; and, appropriately enough, as the first crossing of an aeroplane by a “mere man” was on a Blériot machine, her mount was of that type. Miss Trehawke Davies, it will be remembered, was the first lady to cross the Channel in an aeroplane, but she was a passenger with Mr. Hamel on his Blériot monoplane.
—FLIGHT, No. 173. (No. 16, Vol. IV.), 20 April 1912 at Page 345
Quimby was the first woman to fly across the channel, but that was not her only “first”: On 11 August 1911, after 33 flight lessons over a four-month period at the Moisant Aviation School at Hempstead, Long Island, New York, she had become the first American woman to receive a pilot’s license, Number 37, from the Aero Club of America. She was called as “America’s First Lady of the Air.” Miss Quimby was widely known for her “plum-colored” satin flying suit.
Miss Harriet Qumby, 1911, (Leslie Jones Collection, Boston Public Library)
Harriet Quimby was born 11 May 1875 at Arcadia, Michigan. She was the fourth child of William F. Quimby, a farmer, and Ursula M. Cook Quimby. The family moved to California in 1887, initially settling in Arroyo Grande, and then San Francisco. There, she worked as an actress, and then a writer for the San Francisco Call newspaper, and Leslie’s Illustrated Weekly. Quimby also wrote a number of screenplays for early Hollywood movies which were directed by D.W. Griffiths.
Harriet Quimby was killed at Quincy, Massachusetts, 1 July 1912, when her Blériot XI, circling the airfield at 1,500 feet (457 meters) suddenly pitched down and she and her passenger were thrown out. Miss Quimby was buried at the Kensico Cemetery, Valhalla, New York.

The Blériot XI was a single-seat, single-engine monoplane, designed by Raymond Saulnier and built by Louis Charles Joseph Blériot. It was 26.24 feet (7.998 meters) long with a wingspan of 25.35 feet (7.727 meters) and overall height of 8 feet (2.438 meters). The wings had a chord of 6 feet (1.829 meters). The airplane had an empty weight of 507 pounds (229.9 kilograms).
In its original configuration, the airplane was powered by an air-cooled, 3.774 liter (230.273 cubic inches) R.E.P. two-row, seven-cylinder fan engine (or “semi-radial”) which produced 30 horsepower at 1,500 r.p.m., driving a four-bladed paddle-type propeller. The R.E.P. engine weighed 54 kilograms (119 pounds). This engine was unreliable and was soon replaced by an air-cooled 3.534 liter (215.676 cubic inch) Alessandro Anzani & Co., 60° (some sources state 55°) three-cylinder “fan”-type radial engine (or W-3) and a highly-efficient Hélice Intégrale Chauvière two-bladed fixed-pitch propeller, which had a diameter of 6 feet, 8 inches (2.032 meters). The Anzani W-3 was a direct-drive, right-hand tractor engine which produced 25 horsepower at 1,400 r.p.m. It was 1.130 meters (3 feet 8.49 inches) long, 1.500 meters (4 feet, 11.01 inches) high, and 0.720 meters (2 feet, 4.35 inches) wide. The engine weighed 66 kilograms (145.5 pounds).

Miss Quimby’s airplane, though, was powered by a normally-aspirated, air-cooled, 7.983 liter (487.140-cubic-inch-displacement) Société des Moteurs Gnome Omega 7-cylinder rotary engine which produced 50 horsepower at 1,200 r.p.m. The direct-drive engine turned a two-bladed wooden propeller in a left-hand, tractor configuration. The Omega 7 is 79.2 centimeters (2 feet, 7.2 inches) long, 83.8 centimeters (2 feet, 9.0 inches) in diameter, and weighs 75.6 kilograms (166.7 pounds). The prototype of this engine is in the collection of the Smithsonian Institution National Air & Space Museum.
The Anzani-powered Blériot XI had a maximum speed of 76 kilometers per hour (47 miles per hour) and its service ceiling was 1,000 meters (3,281 feet).
