Latécoère 28-3 F-AJNQ at Saint-Louis du Sénégal, May 1930, with Gimié, Mermoz and Dabry (Keystone)

12–13 May 1930: In an effort to connect the North African and South American air mail routes, Jean Mermoz, the chief pilot of Compagnie générale aéropostale, along with co-pilot and navigator Jean Dabry, and radio navigator Léopold Martial Émile Gimié, departed Saint-Louis, on the western coast of Senegal, French West Africa, enroute to Natal, Brazil.

Their airplane, a pontoon-equipped Latécoère 28-3, was carrying 122 kilograms (269 pounds) of mail and fuel for 30 hours of flight. The crew had named the airplane Comte de la Vaulx, after an early French aeronaut and the founder of the Fédération Aéronautique Internationale.

The aviators flew southwest across the South Atlantic Ocean. Natal was approximately 2,000 miles away. [3,178.879 kilometers; 1,975.264 statute miles; 1,716.595 nautical miles]

Gimié transmitted a radio message: “19º Frame-A.J.N.Q. Mermoz, Dabry, Gimié, partis pour Natal à 10 h. 56 locale.”  (“19º Frame-A.J.N.Q. Mermoz, Dabry, Gimié, left for Natal at 10:56 a.m., local.”) Gimié was an expert in radio-navigation. The airplane was equipped with radios that could be used to triangulate their position using nine land stations and several ships along their course.

A contemporary United Press wire service news report stated that they arrived at Natal at 6:15 a.m., local time. The actual duration of the flight is difficult to determine. Sources very from as few as 17 hours to as many as 21 hours, 24 minutes. The U.S. Centennial of Flight Commission reported that the flight took 19 hours, 35 minutes.

This was the first non-stop flight to cross the South Atlantic.

Antoine Saint Exupéry, a fellow Aéropostale pilot, described a portion of Mermoz’s transatlantic flight in Wind, Sand and Stars:

And yet we have all known flights when of a sudden, each for himself, it has seemed to us that we have crossed the border of the world of reality; when, only a couple of hours from port, we have felt ourselves more distant from it than we should feel if we were in India; when there was a premonition of an incursion into a forbidden world whence it was going to be infinitely difficult to return.

Thus, when Mermoz first crossed the South Atlantic in a hydroplane, as day was dying he ran foul of the Black Hole region, ² off Africa. Straight ahead of him were the tails of tornadoes rising minute by minute gradually higher, rising as a wall is built; and then night came down upon these preliminaries and swallowed them up; and when, and hour later, he slipped under the clouds, he came out into a fantastic kingdom.

Multiple waterspouts.

Great black waterspouts had reared themselves seemingly in the immobility of temple pillars. Swollen at their tops, they were supporting the squat and lowering arch of the tempest, but through the rifts in the arch there fell slabs of light and the full moon sent her radiant beams between the pillars down upon the frozen tiles of the sea. Through these uninhabited ruins Mermoz made his way, gliding slantwise from one channel of light to the next, circling round those giant pillars in which there must have rumbled the upsurge of the sea, flying for four hours through these corridors of moonlight toward the exit from the temple. And this spectacle was so overwhelming that only after he had got through the Black Hole did Mermoz awaken to the fact that he had not been afraid.

Latécoère 28-3 (Late 28.org)

The airplane flown by Mermoz, Dabry and Gimié was a Latécoère 28-3, registration F-AJNQ, built by Société Industrielle d’Aviation Latécoère at Toulouse, France. The airplane’s serial number is reported as both “Nº 909” and “Nº 919.” It was a large, single-engine, high-wing monoplane with an enclosed cabin. Also known as the Laté 28, the airplane could be equipped with fixed landing gear or pontoons for water operations. The airplane’s fuselage was constructed of duralumin, a hardened alloy of aluminum, with a duralumin sheet skin. The wings were also of metal construction, covered with fabric.

The Latécoère 28-3 was 44 feet, 4 inches (13.513 meters) long with a wingspan of 62 feet, 6 inches (19.050) and height of 10 feet, 7½ inches (3.24 meters).

The pontoons were also constructed of Duralumin. Each had ten floatation compartments. They were 26 feet, 4 inches (8.026 meters) long, 4 feet, 5 inches (1.346 meters) wide and 2 feet, 9 inches (0.838 meters) deep.

The Latécoère 28-3 had an empty weight of  5,720 pounds (2595 kilograms), and gross weight of 11,044 pounds (5,010 kilograms). Its fuel capacity was 556 gallons¹ (2,528 liters).

The pilot’s station was an enclosed cockpit at the leading edge of the wing, behind the engine, while the navigator and radio operator were in a cabin below and behind the cockpit. The air mail cargo was placed in a separate compartment.

(The Art of the Airways, by Geza Szurovy)

The Latécoère 28-3 was powered by a single right-hand-tractor, water-cooled, normally-aspirated, 31.403 liter (1,916.351 cubic inches) Hispano Suiza 12Lbr single overhead camshaft (SOHC) 60° V-12 engine with a compression ratio of 6.2:1. This engine was rated at 630 cheval vapeur (621.4 horsepower) at 2,000 r.p.m. The two-bladed, fixed-pitch propeller was driven through a gear reduction unit. The 12Lbr was 1.85 meters (6.07 feet) long, 0.75 meters (2.46 feet) wide and  1.02 meters (3.35 feet) high. It weighed 440 kilograms (970 pounds).

The airplane had a maximum speed of 140 miles per hour (225 kilometers per hour). Its service ceiling was 13,000 feet (3,962 meters).

F-AJNQ departed Natal on 8 June for the return flight to Africa. After about 14 hours, the engine developed a serious oil leak. Mermoz made a forced landing near the despatch boat Phocée, approximately 900 kilometers (560 miles) from their destination. The three crew members and the mail were transferred from F-AJNQ to the Phocée. The airplane was set adrift.

8 May 1927

Charles Nungesser and François Coli, Paris, 8 May 1927. (Smithsonian Institution National Air and Space Museum SI 92-3634)

8 May 1927: At 5:18 a.m., famed World War I aviators François Coli and Charles Eugène Jules Marie Nungesser departed Le Bourget Airport, Paris, aboard their single-engine Levasseur PL.8 biplane, L’Oiseau Blanc (“The White Bird”). Their destination was New York City, non-stop across the Atlantic Ocean.

In 1919, New York hotel owner Raymond Orteig offered a $25,000 prize to the first aviator(s) who flew non-stop from New York to Paris or the reverse. It was several years before the technology had progressed far enough that this became possible.

By 1927, a number of people on both sides of the Atlantic had begun preparations for just such a flight. Coli had begun planning a transatlantic flight as early as 1923. He and a wartime friend, fighter ace Paul Tarascon, were interested in the Orteig Prize, but after being injured in a crash, Tarascon was replaced by Charles Nungesser. Coli was in charge of the flight.

François Coli, a former sea captain, had enlisted as a private in the French Army at the start of the War when no position was offered to him as captain of a French naval vessel. By 1915 he was a commissioned officer and soon promoted to the rank of captain. Severely wounded and no longer able to serve in the infantry, he became a pilot in 1916, and later a squadron commander. In 1918, Coli lost his right eye in an airplane crash. He was considered to be an excellent leader and was known as an expert navigator.

Charles Nungesser was the third-leading French fighter ace of World War I. His was a flamboyant personality. He didn’t like military discipline and was punished for it several times. But he was a highly successful fighter pilot, with an official record of 42 aerial victories. Like Coli, he had been seriously wounded on numerous occasions. He was awarded the Officier de la Legion d’Honneur, Chevalier de la Legion d’Honneur, and the Médaille Militaire, as well as many foreign decorations for valor.

The Sociéte Pierre Levasseur Aéronautique PL.8 was a modified naval reconnaissance airplane, built especially for the Atlantic crossing. The wings were lengthened and the fuselage reinforced. It was 10 meters (32 feet,  9.7 inches) long with a wingspan of 14.680 meters (48 feet, 2 inches) and height of 3.915 meters (12 feet, 10.1 inches). The single-bay biplane had an empty weight of 1,905 kilograms (4,199.8 pounds) and gross weight of 5,030 kilograms (11,089.25 pounds). Three large fuel tanks were installed with a total capacity of 4,000 liters (1,057 gallons) of gasoline.

The White Bird

L’Oiseau Blanc was powered by a liquid-cooled, normally-aspirated 24.429 liter (1,490.751-cubic-inch) Société Lorraine des Anciens Establissements de Dietrich & Cie de Lunéville (Lorraine-Dietrich) 12Ed “broad arrow” (W-12) single overhead camshaft (SOHC) engine which had three banks of four cylinders spaced at 60° angles and driving a single crankshaft. It had a compression ratio of 6:1 and produced 450 chaval vapeur (443.8 horsepower) at 1,850 r.p.m. Reduction gearing reduced propeller r.p.m. by a ratio of 1.545:1. The two-bladed forged duralumin propeller had a diameter of 3.80 meters (12 feet, 8.5 inches). The 12Ed was 1.374 meters (4 feet, 6.10 inches) long, 1.210 meters (3.970 feet, 11.64 inches) wide and 1.138 meters (3 feet, 8.81 inches) high. It weighed 363.874 kilograms (802.205 pounds).

The two aviators planned to land on the water in front of the Statue of Liberty, so they had the PL.8’s landing gear modified so that it could be dropped after takeoff, saving the unneeded weight and decreasing the airplane’s aerodynamic drag. The White Bird‘s maximum speed was 193 kilometers per hour (120 miles per hour), with a cruising speed of 165 kilometers per hour (103 miles per hour). Its range was 7,000 kilometers (4,350 miles). The service ceiling was 7,000 meters (22,966 feet).

When The White Bird left Paris, it was carrying enough fuel for 42 hours of flight. It was escorted as far as the English Channel by several airplanes and crossed the coast at about 7:00 a.m.

Nungesser and Coli never arrived at New York. They were never seen again, and their fate is a mystery.

“This morning I’m going to test the Spirit of St. Louis. It’s the 28th of April — just over two months since I placed our order with the Ryan Company. . . Today, reality will check the claims of formula and theory on a scale which hope can’t stretch a single hair. Today, the reputation of the designing engineer, of the mechanics, in fact of every man who’s had a hand in building the Spirit of St. Louis, is at stake. And I’m on trial too, for quick action on my part may counteract an error by someone else, or a faulty move may bring a washout crash.

The Ryan NYP, registration N-X-211, has been towed from the Ryan Airlines Company factory in San Diego, California, to nearby Dutch Flats for its first test flight. Air Mail pilot Charles A. Lindbergh, representing a syndicate of St. Louis businessmen, has contracted with Ryan to build a single-engine monoplane designed for one man to fly non-stop across the Atlantic Ocean, from New York to Paris.

“I signal chocks away. . . and open the throttle. . . I’ve never felt an airplane accelerate so fast before. The tires are off the ground before they roll a hundred yards. . . .”

And the rest is History.

22 April 1962: Jackie Cochran set 18 Fédération Aéronautique Internationale (FAI) records in one day flying a Lockheed L-1329 JetStar, construction number 5003, FAA registration N172L, and named The Scarlett O’Hara. The route of her flight was New Orleans–Boston–Gander–Shannon–London–Paris–Bonn, with refueling stops at Gander and Shannon.

According to the U.S. Centennial of Flight Commission, Jackie Cochran “…set more speed and altitude records than any other pilot.”

The following are the FAI records that she set on 22 April 1961:

4609, 4615: Speed over a recognized course, Gander, NF (Canada)–Shannon (Ireland): 829.69 kilometers per hour (515.546 miles per hour)

4611, 4616: Speed over a recognized course, Gander, NF (Canada)–London (UK): 749.11 kilometers per hour (465.475 miles per hour)

4612, 4617: Speed over a recognized course, Gander, NF (Canada)–Paris (France): 746.22 kilometers per hour (463.680 miles per hour)

4613, 4618: Speed over a recognized course, Gander, NF (Canada)–Bonn (FRG): 728.26 kilometers per hour (452.520 miles per hour)

4638: Speed over a recognized course, Boston, MA (USA)–Gander, NF (Canada): 816.32 kilometers per hour (507.238 miles per hour)

4639, 4640: Speed over a recognized course, Boston, MA (USA)–Shannon (Ireland): 565.45 kilometers per hour (351.354 miles per hour)

4641, 4642: Speed over a recognized course, Boston, MA (USA)–London (UK): 558.50 kilometers per hour (347.036 miles per hour)

4643, 4644: Speed over a recognized course, Boston, MA (USA)–Paris (France): 564.88 kilometers per hour (351.000 miles per hour)

4645, 4646: Speed over a recognized course, Boston, MA (USA)–Bonn (FRG): 562.56 kilometers per hour (349.559 miles per hour)

12322: Distance, New Orleans, LA (USA)–Gander, NF (Canada): 3,661.33 kilometers (2,275.045 miles)

The first production Lockheed JetStar, c/n 5001, in service with the Federal Aviation Administration, registered N1. (bizjets101)

The Lockheed L-1329 JetStar was the first in a category of small-to-medium-sized jet transports that would become known as the “business jet.” Like many Lockheed airplanes, it was designed by a team led by Clarence L. “Kelly” Johnson, and he retained the first prototype as his personal transport.

The JetStar is operated by two pilots and can be configured for 8 to 10 passengers. The airplane is 60 feet, 5 inches (18.41 meters) long with a wingspan of 54 feet, 5 inches (16.59 meters) and overall height of 20 feet, 5 inches (6.22 meters). The leading edge of the wings are swept to 30°. The JetStar has an empty weight of 24,750 pounds (11,226 kilograms) and maximum takeoff weight (MTOW) of 44,500 pounds.

The two prototype JetStars were powered by two Bristol Siddeley Orpheus engines, but the production models were powered by four Pratt & Whitney JT12A-8 turbojets engines which produced 3,300 pounds of thrust, each. The JetStar 731 was a modification program to replace the turbojet engines with quieter, more efficient and more powerful Garrett AiResearch TFE731 turbofan engines which increased thrust to 3,700 pounds per engine. New production JetStar II airplanes were equipped with these turbofans.

Lockheed L-1329 JetStar (FAI)

The JetStar’s cruise speed is 504 miles per hour (811 kilometers per hour) and its maximum speed is 547 miles per hour (883 kilometers per hour) at 30,000 feet (9,145 meters). The service ceiling is 43,000 feet (13,105 meters) and range is 2,995 miles (4,820 kilometers).

The Lockheed JetStar was in production from 1957 to 1978. 204 were built as civil JetStars and military C-140A Flight Check and C-140B and VC-140B JetStar transports.

The JetStar flown by Jackie Cochran on her record setting flight from New Orleans to Bonn, construction number 5003, eventually was acquired by NASA and assigned to the Dryden Flight Test Center at Edwards Air Force Base, California. It was reregistered as N814NA, and used the call sign NASA 4. No longer in service, NASA 4 is on display at the Joe Davies Heritage Airpark at Air Force Plant 42, Palmdale, California.

4–15 March 1957

U.S. Navy ZPG-2 Bu. No. 141561, “Snow Bird,” prior to departure at NAS South Weymouth, Boston, Massachusetts, 4 March 1957 (NASM)

4 March 1957: At 6:30 p.m., Eastern Standard Time, a United States Navy non-rigid airship, Goodyear ZPG-2, Bu. No. 141561, departed NAS South Weymouth, Boston, Massachussetts, on a long-dstance flight to demonstrate the capabilities of a modern lighter-than-air military “blimp.” The airship had been involved in cold-weather testing and had been given the name, Snow Bird. During this flight, the blimp used the radio call sign “Planner 12.”

CDR Jack R. Hunt, USNR, briefs the crew of Snow Bird prior to departure, 4 March 1957. (Flying Magazine)

Snow Bird was under the command of Commander Jack Reed Hunt, U.S.N.R., a fifteen-year veteran of airship operations. There were two additional pilots, Commander Ronald W. Hoel, U.S.N., and Lieutenant Commander Robert S. Bowser, U.S.N. The crew also consisted of three navigators, Lieutenant Stanley W. Dunton, Lieutenant Charles J. Eadie, and Lieutenant John R. Fitzpatrick. The remainder of the crew were Chief Aviation Electronicsman (ALC) Lee N. Steffan, crew chief and radio; Aviation Machinist’s Mate 1st Class (AD1) Thomas L. Cox, flight mechanic; Aviation Electricians’s Mate 1st Class (AE1) Carl W. Meyer, electrician; Aerographer’s Mate 1st Class (AG1) William S.Dehn, Jr., aerologist and photographer; Aviation Machinist’s Mate 2nd Class (AD2) James R. Burkett, Jr., flight mechanic; Aviation Metalsmith 2nd Class (AM2) George A. Locklear, rigger and cook; and Aviation Electrician’s Mate 2nd Class (AT2) Frank J. Maxymillian, radio. Also on board the air ship was a civilian flight engineer, Mr. Edgar L Moore, a Goodyear Aircraft Corporation Field Representative.

Snow Bird headed east across the Atlantic Ocean, passing north of the Azores on 7 March. At this point, the airship had burned off enough fuel that it was light enough to cruise on one engine. This allowed a much greater range. (A lateral rive shaft between engines allowed both propellers to continue turning.) Late in the third day the flight, the blimp reached the west coast of Portugal, having completed the first Atlantic crossing by a lighter-than-air craft in 12 years.

Snow Bird turned south, heading for Casablanca on the west coast of North Africa, which it reached the morning of 8 March. The airship continued south along the African coast before turning west to re-cross the ocean. The route took the blimp past the Canary and Cape Verde Islands, and then onward to the Virgin Islands. Arriving back in the United States, Snow Bird made landfall at Miami Beach on the afternoon of 14 March.

Admiral Arleigh Burke

A radio message was sent to the crew of Planner 12 by Admiral Arleigh Burke, Chief of Naval Operations:

HEARTIEST CONGRATULATIONS ON ESTABLISHING A NEW WORLD ENDURANCE RECORD FOR AIRSHIPS X YOUR UNTIRING EFFORTS AND DEVOTION ARE MOST COMMENDABLE X THIS FLIGHT DEMONSTRATES AN INCREASED ASW AND AEW CAPABILITY AND OTHER ACHIEVEMENTS WHICH SERVE TO DEMONSTRATE A CONTINUING SEARCH FOR TECHNOLOGICAL ADVANCES BY THE U S NAVY X WELL DONE X ARLEIGH BURKE

Not finished with its voyage, the airship next headed to Dry Tortugas at the far western end of the Florida Keys, and then finally landed at NAS Key West, Florida, on 15 March.

ZPG-2 Flight Track (Flying Magazine)

Snow Bird had traveled 9,448 miles (15,205 kilometers) without landing or refueling. The Fédération Aéronautique Internationale (FAI) lists this as “the longest recorded airship flight.” This exceeded the distance record set by Graf Zeppelin, flying from Friedrichshaven, Germany, to Tokyo, Japan, (11,247 kilometers) 15–19 August 1929. From takeoff at NAS South Weymouth to landing at NAS Key West, the total duration of the flight was 264 hours, 14 minutes.

The crew was met by a large group of dignitaries. Commander Reed was presented the Distinguished Flying Cross by Fleet Admiral William Frederick Halsey, Jr., United States Navy, one of the greatest military leaders of World War II.

Commander Hunt was later presented the Harmon International  Trophy by President Dwight D. Eisenhower.

Goodyear ZPG-2 Bu. No. 141561 was built by the Goodyear Aircraft Corporation at Akron, Ohio. It was the 11th of 12 “N-class” airships which were used for patrol, anti-submarine warfare ASW), and when equipped with radar, for airborne early warning (AEW).

The ZPG-2 is 343 feet (105 meters) long and the envelope has a maximum diameter of 76 feet (23 meters). A two-deck control car was suspended beneath the envelope. The airship had an overall height of 107 feet (33 meters). Bouyancy was provided by 1,011,000 cubic feet (28,628 cubic meters) of Helium.

There are four fins placed in a X-pattern at the tail of the ZPG-2, called ruddervators. (These were similar to the fins used on the experimental submarine USS Albacore (AGSS-569) several years later.) The ruddervators allowed the airship to be controlled by a single control column, a change from the two controls used previously. Also, the decreased vertical span of the fins allowed greater ground clearance, so that the blimp could takeoff at steeper angles than if it had been equipped with the standard cruciform fins.

The Goodyear ZPG-2 was powered by two air-cooled, supercharged, 1,301.868 cubic inch displacement (21.334 liter) Wright Aeronautical Division R-1300-2 (Cyclone 7 865C7BA1) seven-cylinder radial engines mounted outside the control car. The R-1300-2 was a direct-drive engine with a compression ratio of 6.2:1. It was rated at 700 horsepower at 2,400 r.p.m., and 800 horsepower at 2,600 r.p.m., for takeoff, using 91/96 octane aviation gasoline. The engines turned three-bladed Curtiss Electric variable pitch, reversible propellers. The R-1300-2 was 48.12 inches (1.222 meters) long, 50.45 inches (1.281 meters) in diameter, and weighed 1,067 pounds (484 kilograms).

The ZPG-2 had a cruise speed of 57 miles per hour (92 kilometers per hour) and maximum speed of 80 miles per hour (129 kilometers per hour). Its normal endurance was three days.

Bu. No. 141561’s cockpit, nose cone and a frame of a ruddervator are displayed at the National Naval Aviation Museum, NAS Pensacola, Florida.

Jack Reed Hunt

Jack Reed Hunt was born at Red Oak, Iowa, 18 May 1918. He was the second of seven children of Smith Reed Hunt, a baker, and Blanche Luise Seefeldt Hunt. The family moved to southern California, where Jack grew up.

Jack R. Hunt joint the United States Navy on 4 April 1942. He was trained as an airship pilot and flight instructor. Hunt was commissioned as an Ensign in the United States Naval Reserve, 1 October 1942, and promoted to Lieutenant (junior grade), 1 October 1943. Hunt remained in the Navy following World War II. He was promoted to Lieutenant Commander 1 August 1951, and to Commander, 1 July 1956.

From 1963 until 1984, Jack Hunt was the president of Embry-Riddle Aeronautical University, a fully-accredited aerospace university.

Hunt was married three times (Bethel, Donna and Lynne) and had seven children. He died 7 January 1984, at the age of 65 years.
