22 April 1961: 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)

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.

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.

18 March 1937, 5:40 a.m.: Amelia Earhart and her crew sighted Diamond Head on the island of Oahu, Hawaiian Islands. The Electra landed at Wheeler Army Airfield, Honolulu, after an overnight flight from Oakland, California, completing the first leg of a planned around-the-world flight in 15 hours, 47 minutes.

Also aboard were Paul Mantz, Amelia’s friend and adviser, as co-pilot, navigator Captain Frederick Joseph Noonan, formerly of Pan American Airways, and Captain Harry Manning of United States Lines, acting as radio operator and navigator. The airplane was Earhart’s Lockheed Electra 10E Special, registration NR16020.

About an hour after takeoff from Oakland, California, the Electra overtook the Pan American Airways Hawaii Clipper, which had departed San Francisco Bay an hour-and-a-half before Earhart. She took photographs of the Martin M-130 flying boat.

In her log, Amelia Earhart described the sunset over the Pacific Ocean:

“. . . golden edged clouds ahead, then the golden nothingness of sunset beyond. . .  The aft cabin is lighted with a weird green blue light, Our instruments show pink. The sky rose yellow. . . Night has come. The sea is lovely. Venus is setting ahead to the right. The moon is a life-saver. It gives us a horizon to fly by. . . .”

Amelia: The Centennial Biography of an Aviation Pioneer, by Donald M. Goldstein and Katherine V. Dillon, Brassey’s, Wahington and London, 1997, Chapter 18 at Page 171.

On arrival at Hawaii, Earhart, saying that she was very tired, asked Paul Mantz to make the landing at Wheeler Field.

Amelia Earhart’s 1936 Electra 10E Special, serial number 1055, was the fifth of fifteen built by the Lockheed Aircraft Corporation at Union Air Terminal, Burbank, California (now, Hollywood Burbank Airport, BUR). Designed to carry as many as ten passengers, NR16020 had been modified to carry fuel for 20 hours of flight. Amelia first flew the Electra with a Lockheed test pilot, Elmer C. McLeod, 21 July 1936, and took delivery on her 39th birthday, 24 July. The airplane cost $80,000.

The Lockheed Electra 10 was designed by Hall Hibbard, and was Clarence L. “Kelly” Johnson’s first assignment when he went to work at Lockheed. It was 38 feet, 7 inches (11.760 meters) long with a wingspan of 55 feet, 0 inches (16.764 meters) and overall height of 10 feet, 1 inch (3.073 meters).

While the basic Model 10 had an empty weight of 6,454 pounds (2,927.5 kilograms), Amelia Earhart’s modified Electra 10E Special had an empty weight of 7,265 pounds (3,295.4 kilograms), partly as a result of the additional fuel tanks which had been installed. Fully fueled, NR16020 carried 1,151 gallons (4,357 liters) of gasoline.

NR19020 was powered by two air-cooled, supercharged, 1,343.804-cubic-inch-displacement (22.021 liter) Pratt & Whitney Wasp S3H1 single-row nine-cylinder radial engines with a compression ratio of 6:1. These engines used a single-stage supercharger. The S3H1 had a Normal Power rating of 550 horsepower at 2,200 r.p.m. to 5,000 feet (1,524 meters), and 600 horsepower at 2,250 r.p.m for Takeoff, using 80/87 aviation gasoline. The direct-drive engines turned two-bladed Hamilton Standard variable-pitch, constant-speed propellers with a diameter of 9 feet, 7/8-inch (2.675 meters). The Wasp S3H1 was 3 feet, 7.01 inches (1.092 meters) long, 4 feet, 3.60 inches (1.311 meters) in diameter, and weighed 865 pounds (392 kilograms).

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. 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.

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 nest 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 coul 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 commission 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.

25 February 1927: Acting on behalf of a syndicate of St. Louis business men, Charles A. Lindbergh contracts Ryan Airlines Company of San Diego to design and build a single-engine monoplane for a flight from New York to Paris. This would become the Spirit of St. Louis. The cost is $10,580.

“The Ryan Airlines factory is in an old, dilapidated building near the waterfront. I feel conspicuous driving up to it in a taxicab. A couple of loafers stare at me as I pay my fare. There’s no flying field, no hangar, no sound of engines warming up; and the unmistakable smell of dead fish from a near-by cannery mixes with the banana odor of dope from drying wings. . .

“I open the door to a small, dusty, paper-strewn office. A slender young man advances to meet me—clear, piercing eyes, intent face. He introduces himself as Donald Hall, chief engineer for Ryan Airlines, Incorporated. . . .”

The Spirit of St. Louis, by Charles A. Lindbergh, Charles Scribner’s Sons, New York, 1953, Chapter III, Page 79.

“I check the wording and hand my telegram to the girl in the office. I’m ready to cast my lot with the Ryan organization. I believe in Hall’s ability; I like Mahoney’s enthusiasm. I have confidence in the character of the workmen I’ve met. This company is a fit partner for our organization in St. Louis. They’re as anxious to build a plane that will fly to Paris as I am to fly it there.”
