30 April–13 May 1963: Betty Miller, a 37-year-old flight instructor from Santa Monica, California, became the first woman to complete a solo Trans-Pacific flight. She was also the first pilot to make a Trans-Pacific flight without a navigator.
Betty Miller was delivering a twin-engine Piper PA-23-160 Apache H, N4315Y, from the United States to its owner in Australia, Fred Margison. An auxiliary fuel tank was placed in the passenger compartment.
Mrs. Miller began her flight from Oakland, California, at 6:35 a.m., Pacific Standard Time. The first leg was approximately 2,400 miles (3,682 kilometers) to Honolulu on the island of Oahu, Hawaii, flown in 17 hours, 3 minutes. She was delayed there for 4 days while a radio was repaired.
The next stop was Canton Island, a small island in the Phoenix Islands, just south of the Equator and approximately half-way between Hawaii and Fiji. The elapsed time for this 1,700-mile (2,736 kilkometers) flight was 13 hours, 6 minutes. From Canton to Fiji was 1,250 miles (2,012 kilometers). The elapsed time was 8 hours, 27 minutes. On the fourth leg, intended to be the final stage, she was forced to divert to Noumea, New Caledonia, because of severe weather.
With delays for rest and waiting for good weather, Miller’s flight took nearly two weeks. She took off from Nadi Airport, Viti Levu, Fiji, at 4:47 a.m., local, and finally arrived at Eagle Farm Airport, Brisbane, Queensland, at 10:20 p.m., Australian Eastern Standard Time, after crossing 7,400 miles (11,909 kilometers) of ocean, in a total of 51 hours, 38 minutes in the air.
Contemporary newspapers called Miller “the flying housewife,” which demeaned her actual qualifications. At the time of her Trans-Pacific flight, she was a commercial pilot and flight instructor, rated in single- and multi-engine airplanes and helicopters. She owned and operated a flight school and charter company based at Santa Monica Airport on the Southern California coast. In fourteen years as a pilot, Betty Miller had logged more than 6,500 hours of flight time.
President John F. Kennedy awarded Mrs. Miller the Federal Aviation Administration Gold Medal for Exceptional Service. On 14 September 1964, President Lyndon Johnson presented her with the Harmon International Trophy. (Also receiving the Harmon at the ceremony were Astronaut Gordon Cooper and test pilot Fitzhugh Fulton.)
Two years later, Mrs. Miller flew across the Atlantic Ocean.
Finally, in another first, the photograph of Betty Miller arriving at Brisbane was the very first to be transmitted by a new wire-photo process.
Betty Jean Verret was born 6 April 1926 at Venice, California. She was the second of three daughters of Earday Verret, a street car conductor, and Bertha DeLay Verret. She graduated from Venice High School in 1942.
Miss Verret was employed by the Civil Aeronautics Administration as an Aircraft Communicator. While working at Wendover, Utah, she met Chuck Miller. They married and lived in Santa Monica, California, where they operated a flight school.
Mrs. Miller was a member of the Ninety-Nines, the Whirly-Girls, and was chair of the FAA Women’s Advisory Committee.
Betty Jean Verret Miller died 21 February 2018 at Bountiful, Utah, at the age of 91 years.
The airplane flown by Betty Miller was a Piper PA-23-160 Apache H, serial number 23-2039, manufactured in December 1961 by the Piper Aircraft Corporation at Vero Beach, Florida. It was assigned U.S. registration N4315Y and was painted white and “El Paso Brown” (a dark metallic brown color). In January 1962 the new Apache was delivered to Brown Flying Services, San Antonio, Texas.¹
The Piper PA-23-160 Apache H was a 4-place, twin-engine light airplane with retractable tricycle landing gear. It was 27 feet, 2 inches (8.280 meters) long with a wingspan of 37 feet, 0 inches (11.278 meters) and overall height of 10 feet, 1 inch (3.073 meters). The airplane had an empty weight of 2,230 pounds (1,011.5 kilograms) and maximum gross weight of 3,800 pounds (1,723.7 kilograms).
The Apache H was powered by two air-cooled, normally-aspirated, 319.749-cubic-inch-displacement (5.240 liter) Lycoming O-320-B2B horizontally-opposed 4-cylinder overhead valve (OHV) engines with a compression ratio of 8.5:1. The O-320-B2B is a direct-drive, right-hand tractor engine, rated at 160 horsepower at 2,700 r.p.m. The O-320-B2B is 2 feet, 5.56 inches (0.751 meters) long, 2 feet, 8.24 inches (0.819 meters) wide and 1 foot, 10.99 inches (0.584 meters) high. It weighs 278 pounds (126.1 kilograms). The engines turned two-bladed Hartzell constant-speed propellers.
The PA-23-160 had a cruise speed of 150 knots (173 miles per hour/278 kilometers per hour) and maximum speed was 159 knots (183 miles per hour/295 kilometers per hour). The service ceiling was 17,000 feet (5,182 meters).
N4315Y was re-registered VH-IMB, 22 May 1963, after its arrival in Australia. The airplane remains operational.

28 April 1937: The first transpacific flight by a commercial passenger airliner is completed when Pan American Airways’ Martin M-130, China Clipper, arrived at Hong Kong. The flight had departed San Francisco Bay, California, on 21 April with 7 revenue passengers and then proceeded across the Pacific Ocean by way of Hawaii, Midway Island, Wake Island, Guam, Manila, Macau, and finally Hong Kong. The Reuters news agency briefly reported the event:
AIR LINK AROUND WORLD FORGED.
China Clipper Lands At Hong Kong.
Hong Kong, April 28.
The Pan-American Airways flying boat China Clipper landed at 11:55 this morning from Manila and Macao. This links the Pan-American and Imperial Airways, completing the commercial air link round the world. —Reuter.
—The Straits Times, 28 April 1937, Page 1, Column 4.
The Oakland Tribune reported:
AIR CLIPPER SPANS SEAS TO HONGKONG
U.S. MAIL TO CHINA LANDED IN SIX DAYS
Plane Crew Feted at End Of Historic Hop From U.S. Via Philippines
HONGKONG, April 28.—(AP)—A 30-year dream of ’round-the-world air service became reality today with the arrival of the Hongkong Clipper from Manila on the first regular flight between the two cities.
The clipper, bridging the last 700-mile gap in the America-Asia service, placed the final link in an airplane chain whereby it is possible to encircle the world in less than a month, using scheduled commercial planes.
The craft brought 2500 pounds of American cargo, including 100,000 letters and newspapers from the United States only six days old. The papers left Alameda, Calif., last Thursday aboard China Clipper, being transferred to the Hongkong Clipper at Manila. ¹
A large crowd welcomed the clipper at Kaitak Airport. Included were Acting Governor N. L. Smith and representatives of all of the colony’s government and commercial activities.
The clippers’ pilot, A. E. Laporte, and crew were escorted to a dais at the hangar, where the acting governor gave a speech of welcome.
The plane, on its return flight on Thursday, is expected to carry 2500 pounds of cargo, including 40,000 letters.
At a reception for the fliers, the acting governor said:
“We are celebrating the welding of the last link in world air communication. The lessening of the physical gaps is the surest way of ending misunderstandings which have occurred between nations in the past.
“Hongkong offers congratulations, welcomes this American transpacific air service and hopes it will be another bond in the chain of goodwill.”
Laporte said the Manila-Hongkong flight was “uneventful,” despite poor weather conditions necessitating intermittent blind flying.
The China Clipper, NC14716, was the first of three Martin M-130 four-engine flying boats built for Pan American Airways and was used to inaugurate the first commercial transpacific air service from San Francisco to Manila in November, 1935. Built at a cost of $417,000 by the Glenn L. Martin Company in Baltimore, Maryland, it first flew on 20 December 1934, and was delivered to Pan Am on October 9, 1935.
The airplane was operated by a flight crew of 6 to 9, depending on the length of the flight, plus cabin staff, and could carry 18 passengers on overnight flights or a maximum 36 passengers.
The Martin M-130 was 90 feet, 10.5 inches (27.699 meters) long with a wingspan of 130 feet, 0 inches (39.624 meters). It was 24 feet, 7 inches (7.493 meters) high. Its maximum takeoff weight was 52,252 pounds (23,701 kilograms).
The flying boat was powered by four air-cooled, supercharged, 1,829.389-cubic-inch displacement (29.978 liters) Pratt & Whitney Twin Wasp S2A5-G engines. These were two-row, 14-cylinder radial engines with a compression ratio of 6.7:1. The S2A5-G was rated at 830 horsepower at 2,400 r.p.m., and 950 horsepower at 2,550 r.p.m. for takeoff, burning 87-octane gasoline. They drove three-bladed Hamilton Standard Hydromatic constant-speed propellers through a 3:2 gear reduction. The engine was 3 feet, 11.88 inches (1.216 meters) in diameter and 4 feet, 8.75 inches (1.441 meters) long. It weighed 1,235 pounds (560 kilograms).
The airplane had a maximum speed of 180 miles per hour (290 kilometers per hour), and a cruise speed of 130 miles per hour (209 kilometers per hour). The service ceiling was 10,000 feet (3,048 meters) and its range was 3,200 miles (5,150 kilometers).
¹ There may be confusion as to which airplane was flown from Manila to Hong Kong. Most newspapers identified it as China Clipper, while the Oakland Tribune called it Hongkong Clipper.
Pan American’s Hong Kong Clipper was a Sikorsky S-42, NC823M, which had entered service in December 1934. Many newspapers dated 28 April 1937 showed a photograph of NC832M arriving at Auckland, New Zealand, after a four-day, 7,000-mile survey flight from the United States.
Entering service in 1934, the airline had originally named the NC823M West Indies Clipper. This was changed to Pan American Clipper, and later, Hong Kong Clipper. The airplane crashed on takeoff and sank near Antilla, Cuba, 7 August 1944.
15 March 1962: Flying Tiger Line Flight 7815/13 was a chartered flight for the Military Air Transport Service (M.A.T.S. Flight 739/14), from Travis Air Force Base, Fairfield, California, to Saigon, Republic of Vietnam, with scheduled refueling stops at Honolulu, Hawaii; Wake Island; Naval Air Station Agana, Guam; and Clark Air Force Base, Luzon, Philippine Islands. The flight departed Travis at 0545 G.M.T., 14 March.
The airliner was a Lockheed L-1049H Super Constellation, N6921C, under the command of Captain Gregory P. Thomas. The flight crew consisted of three pilots, two flight engineers, and two navigators/radio operators. There were four stewardesses in the passenger cabin, with 96 passengers. Three of the passengers were Vietnamese military personnel, while the remainder were U.S. Army electronics and communications specialists.
The Super Constellation departed Guam for Luzon at 1257 G.M.T, 15 March. It climbed to 18,000 feet (5,486 meters). The estimated flight time for this leg was 6 hours, 19 minutes. The airplane carried sufficient fuel for 9 hours, 30 minutes of flight.
At 1422 G.M.T., M.A.T.S. flight 739/14 radioed the Guam International Flight Service Station, reporting their position at 1416 hours as North 13° 40′, East 140°, and cruising at 18,000 feet (5,486 meters). The navigator gave the flight’s estimated position at 1530 G.M.T. as N. 14° 00′, E. 135° 00′.
There was no 1530 hours position report from Flight 739. Beginning at 1533 G.M.T., the Guam I.F.S.S. began attempting to contact the airliner, but was unsuccessful. At 1943 hours, the Joint Rescue Coordination Centers at NAS Agana and Clark AFB began search and rescue operations. At 2227 hours, the airliner was declared lost.
The crew of the Standard Oil Company tanker S.S. T. L. Lenzen reported that at 1530 G.M.T., (1:30 a.m., local time), five persons on board had witnessed a midair explosion near Flight 739’s estimated position for that time. The flash was bright enough to illuminate the ship’s decks.
It was established, upon interrogation of five of the crew members, that shipboard lookouts had observed a midair explosion at the approximate position and time when N 6921C was expected to reach 14°00′ North and 135°00′ East. It was recalled that a vapor trail, or some phenomenon resembling a vapor trail, was first observed overhead and slightly to the north of the tanker and moving in an east to west direction. The Lenzen was cruising on a heading of 077° at this time. As this vapor trail passed behind a cloud, there occurred an explosion which was described by the witnesses as intensely luminous, with a white nucleus surrounded by a reddish-orange periphery with radial lines of identically colored light. The explosion occurred in two pulses lasting between two and three seconds and from it two flaming objects of unequal brightness and size apparently fell, at different speeds, into the sea. During the last 10 seconds of the fall of the slower of the two objects, a small bright target was observed on the ship’s radar bearing 270°, range 17 miles.
The captain of the Lenzen stated that he arrived on deck in time to observe the fall of the slower object for approximately 10 seconds before it disappeared from view. He estimated its position in reference to a star and ordered the ship’s course reversed and, after aligning the heading of the vessel with the star, found his heading to be 270°—the same as the bearing of the target previously seen on radar. The captain reported that the weather at that time was: ‘moonlight, clear atmosphere, 1/4 covered sky by small cumulus clouds evenly distributed.’ The ship proceeded to the position of the radar target and searched the area until 2105 at which time the original course was resumed. No signals or unusual sightings were reported.
The subsequent search, one of the most extensive ever conducted in the history of aviation, covered 144,000 square miles and utilized 1,300 people, 48 aircraft, and 8 surface vessels. A total of 377 air sorties were flown which involved over 3,417 flying hours. Despite the thoroughness of the search, nothing was found that could conceivably be linked to the missing aircraft or its occupants.
—CIVIL AERONAUTICS BOARD, AIRCRAFT ACCIDENT REPORT, File No. 1-0002, 8 April 1963, at Pages 8–9
Probable Cause: The Board is unable to determine the probable cause of this accident from the evidence now available.
BURBANK, Calif. (AP)—Sabotage, already suspected in the mysterious disappearance of an airliner loaded with American troops, would be considered a stronger possibility than ever if it turns out the plane blew up.
A Flying Tiger Lines official said Sunday experts consider it impossible for a violent explosion to occur about aboard its Super Constellation under normal conditions.
“We’ve gone over it thoroughly the last few days,” said Frank B. Lynott, executive vice president for operation. “The only explosions known to happen would be in empty wing tanks, and none of these would have been empty then. So far as blowing completely apart,” he said, “there’s nothing that powerful aboard: fuel tanks don’t just go off like that.”
—Hartford Courant, Hartford, Connecticut, Volume CXXV, Number 78, Monday, 19 March 1962, Page 21 at Column 2
Another speculative theory was that the airliner had been hijacked in order to kidnap the passengers.
The flight crew of M.A.T.S. Flight 739/14 were all highly experienced airmen. Captain Gregory P. Thomas had been employed by the Flying Tiger Line since 7 July 1950. He held an Airline Transport Pilot certificate, and was type-rated in the Curtiss C-46, Douglas DC-3, DC-4, DC-6, and Lockheed L-1049H. He had flown a total of 19,500 flight hours, with 3,562 hours in the L-1049H. He was 48 years old and lived in Red Bank, New Jersey. According to contemporary news reports, Captain Thomas was “a colorful and heroic flier.” (In 1957, he had ditched a Douglas DC-6 in Jamaica Bay with no loss of life.)
First Officer Robert J. Wish had worked for FTL since 25 January 1951. He held an ATP certificate, with type ratings for C-46, DC-4 and L-1049H.had a total of 17,500 flight hours, with 3,374 hours in the L-1049H. Wish was also 48 years old, and lived in Hidden Hills, California.
Second Officer Robbie J. Gayzaway [Gazaway or Gazzaway?], 39 years old, from Fillmore, California, was employed by FTL 7 January 1953. He held an ATP certificate with an L-1049H type rating. He had flown 5,500 hours, with 900 in the L-1049H.
Flight Engineer George Michael Nau was hired by the Flying Tiger Line 15 December 1956. He held an F.A.A. Flight Engineer certificate. He had flown 1,235 hours in the L-1049H. Nau was 38 years old and lived in Pacoima, California.
A second flight engineer was Clayton E. McClellan, 33 years old, from San Mateo, California. He was also a certified flight engineer. He had worked for FTL since 4 April 1960. He had approximately 1,090 hours in the L-1049H.
Navigator William T. Kennedy was hired by FTL 13 February 1962. He was 45 years old, from Braintree, California. He held both navigator and radio operator licenses.
Navigator Grady Reese Burt, Jr., was hired 14 February 1962. He also held both navigator and radio operators licenses. He lived in Baldwin Park, California.
The cabin crew were Senior Flight Attendant Barbara Jean Walmsley from Santa Barbara, California; Hildegard Muller; Christel Diana Reiter of San Mateo; and Patricia Wassum.
The Super Constellation remains missing today, and all 107 persons on board are presumed to have died. With respect to the loss of life, this was the worst accident involving a Lockheed Constellation.
N6921C was the second Lockheed L-1049H Super Constellation lost by Flying Tiger Line on 15 March 1962.
The first was N6911C (Lockheed serial number 4804), under the command of Captain Morgan W. Hughes of San Mateo, California. It was also a M.A.T.S. chartered flight, FTL Flight 7816/14, and, like N6921C, had departed from Travis Air Force Base on the night of 14 March. It was reportedly carrying a “secret military cargo” to Kadena Air Force Base, Okinawa.
While on a Ground Controlled Approach (GCA) approach to NAS Adak Island (in the Aleutian Islands of Alaska) the airliner was consistently below the glide path. Despite seven separate warnings from the ground controller, at 1214 G.M.T., the airplane’s landing gear struck rocks 328 feet (100 meters) short of the runway threshold. It then slid for 2,000 feet (610 meters) along the runway, coming to rest just off its edge. The airliner caught fire and was destroyed. Of the 7 persons on board, 1, James M. Johnstone, a flight engineer, was killed.
Captain Hughes had a total of 13,000 flight hours, with 3,055 hours in the L-1049H. The co-pilot, First Officer Thomas M. Mitchell, had 19,000 flight hours with 1,211 hours in type.
The Civil Aeronautics Board determined that the Probable Cause of this accident was “. . . attributed to the pilots’ misjudgement of distance and altitude during the final approach.”
Flying Tiger Line lost two more L-1049H Super Constellations, N6923C and 6913C, in 1962.
Lockheed L-1049H Super Constellation N6921C (LAC serial number 4817) was delivered to the Flying Tiger Line in 1957. It was a large, four-engine, long-range airliner. The airplane was operated by two pilots, a flight engineer and a navigator.
The L-1049 series was 18 feet, 4 inches (5.588 meters) longer than the preceding L-749 Constellation, with cylindrical “plugs” installed fore and aft of the wing. The L-1049H was the final commercial variant of the Super Constellation series. It could be converted from a passenger airliner to an air freighter configuration in a few hours. The L-1049 was 113 feet, 3.7 inches (34.536 meters) long, with a wingspan of 123 feet, 0 inches (37.490 meters), and overall height of 24 feet, 9.5 inches (7.557 meters). The fuselage had a maximum diameter of 11 feet, 7½ inches ( meters).
The total wing area was 1,650 square feet (153.3 square meters). The wings’ leading edges were swept aft 7° 28.7′, while the trailing edges swept forward 3° 13′. They had 7° 36.6′ dihedral.
The L-1049H had an empty weight of approximately 73,000 pounds (33,122 kilograms. N6921C had a maximum allowable gross weight of 141,845 pounds (64,340 kilograms). When it departed Guam, it carried 25,552 pounds (11,590 kilograms) of 115/145-octane aviation gasoline, and its gross weight was 132,554 pounds (60,125 kilograms).
N6921C was powered by four air-cooled, direct-fuel-injected, 3,347.662 cubic-inch-displacement (54.858 liters) Wright Aeronautical Division 988TC18EA3 turbocompound engines with a compression ratio of 6.70:1. The turbocompound engine used captured exhaust gases to drive three Power Recovery Turbines. These PRTs were coupled to the engine’s crankshaft. This system added approximately 450 horsepower to the engine’s total power output.
The 988RC18EA3 had Normal Power ratings of 2,860 horsepower at 2,650 r.p.m. at Sea Level; 2,920 horsepower at 2,650 r.p.m. at 4,800 feet (1,463 meters); 2,450 horsepower at 2,600 r.p.m. at 16,400 feet (4,999 meters). Its Maximum Power ratings were 3,400 horsepower at 2,900 r.p.m. to 4,000 feet (1,219 meters) for Take Off; and 2,600 horsepower at 2,600 r.p.m. at 15,200 feet (4,633 meters). 115/145-octane aviation gasoline was required.
The engines turned three-bladed Hamilton Standard or Curtiss Electric propellers through a 0.4375:1 propeller gear reduction. The reduction gears were strengthened to support 4,000 horsepower. The Wright 988TC18EA3 was 7 feet, 5.53 inches (2.274 meters) long, 4 feet, 8.59 inches (1.473 meters) in diameter, and weighed 3,640 pounds, ± 1% (1,651 kilograms).
The L-1049 had a maximum speed for normal operations (VNO) of 260 knots (299 miles per hour/482 kilometers per hour) and a maximum speed (VNE) of 293 knots (337 miles per hour/543 kilometers per hour) up to 11,000 feet (3,353 meters). VNO was reduced by 9 knots, and VNE reduced by 11 knots, for each 2,000 foot (610 meters) increase in altitude above 11,000 feet.
The maximum operating altitude for the L-1049 was 25,000 feet (7,620 meters). Its maximum range was 4,140 miles (6,663 kilometers).
N6921C had flown a total 17,224 hours in just under five years. It was properly certified and maintained, and had no known discrepancies. N6911C had 16,038 hours, TTAF.
22 November 1935: The Pan American Airways flying boat, China Clipper, a Martin M-130, NC14716, departed Alameda, California (an island in San Francisco Bay) at 3:46 p.m., Friday, and arrived at Honolulu at 10:39 a.m., Saturday, completing the first leg of a five-day trans-Pacific flight to Manila in the Philippine Islands.
The aircraft commander was Captain Edwin Charles Musick, with First Officer Robert Oliver Daniel (“Rod”) Sullivan. The navigator was Frederick Joseph Noonan, who would later accompany Amelia Earhart on her around-the-world flight attempt. There were also a Second Officer and two Flight Engineers. The cargo consisted of 110,000 pieces of U.S. Mail.
Pan Am personnel called the Clipper “Sweet Sixteen,” referring to its Civil Aeronautics Board registration number, NC14716. The airplane and Humphrey Bogart starred in a 1936 First National Pictures movie, “China Clipper.”
NC14716 was the first of three Martin M-130 four-engine flying boats built for Pan American Airways and was used to inaugurate the first commercial transpacific air service from San Francisco to Manila in November, 1935. Built at a cost of $417,000 by the Glenn L. Martin Company in Baltimore, Maryland, it was delivered to Pan Am on October 9, 1935. The airplane’s serial number was 558.
The M-130 was operated by a flight crew of 6–9, depending on the length of the flight, plus cabin staff, and could carry 18 passengers on overnight flights, or a maximum 36 passengers.
The Martin M-130 was 90 feet, 10.5 inches (27.699 meters) long with a wingspan of 130 feet, 0 inches (39.624 meters). It was 24 feet, 7 inches (7.493 meters) high. The total wing area was 2,315 square feet (215 square meters), including the “sea wings”. Its maximum takeoff weight was 52,252 pounds (23,701 kilograms).
The flying boat was powered by four air-cooled, supercharged Pratt & Whitney Twin Wasp S2A5-G two-row 14-cylinder radial engines with a compression ratio of 6.7:1. They had a normal power rating 830 horsepower at 2,400 r.p.m., and 950 horsepower at 2,550 r.p.m. for takeoff. They drove three-bladed Hamilton Standard Hydromatic constant-speed propellers through a 3:2 gear reduction. The S2A5-G was 3 feet, 11.88 inches (1.216 meters) in diameter, 4 feet, 8.75 inches (1.441 meters) long, and weighed 1,235 pounds (560 kilograms).
The airplane had a cruise speed of 130 miles per hour (209 kilometers per hour) and a maximum speed of 180 miles per hour (290 kilometers per hour). The M-130’s service ceiling was 10,000 feet (3,048 meters). Its range was 3,200 miles (5,150 kilometers).
The rigid airship Graf Zeppelin, LZ 127, under the command of Dr. Hugo Eckener, departed Lakehurst Naval Air Station, New Jersey, 8 August 1929, heading east across the Atlantic Ocean on the first aerial circumnavigation by air. The flight was sponsored by publisher William Randolph Hearst, who had placed several correspondents aboard.
Graf Zeppelin was named after Ferdinand Adolf Heinrich August Graf von Zeppelin, a German general and count, the founder of the Zeppelin Airship Company. The airship was constructed of a lightweight metal structure covered by a fabric envelope. It was 776 feet (236.6 meters) long. Contained inside were 12 hydrogen-filled buoyancy tanks, fuel tanks, work spaces and crew quarters.
A gondola mounted underneath contained the flight deck, a sitting and dining room and ten passenger cabins. The LZ-127 was manned by a 36 person crew and could carry 24 passengers.
LZ-127was powered by five water-cooled, fuel injected 33.251 liter (2,029.1 cubic inches) Maybach VL-2 60° V-12 engines producing 570 horsepower at 1,600 r.p.m., each. Fuel was either gasoline or blau gas, a gaseous fuel similar to propane. The zeppelin’s maximum speed was 80 miles per hour (128 kilometers per hour).
After refueling at the Kasumigaura Naval Air Station, Tokyo, Japan, Graf Zeppelin started east across the Pacific Ocean on 23 August, enroute to Los Angeles, California. This leg crossed 5,998 miles (9,653 kilometers) in 79 hours, 3 minutes. This was the first ever non-stop flight across the Pacific Ocean.
LZ 127 arrived at Mines Field (now, LAX) at 1:50 a.m., 26 August 1929. There were an estimated 50,000 spectators.
