14 May 1973: At 12:30:00 p.m. Eastern Standard Time, America’s first orbital space station, Skylab, was launched by a Saturn V Launch Vehicle, SA-513, from Launch Complex 39A at the Kennedy Space Center, Cape Canaveral, Florida. First motion was detected at T + 000:00:00.22.

After first stage separation, the S-IC/S-II interstage connector failed to separate from the second stage. because of this, orbital insertion occurred at T + 000:09:59.0; 0.64 seconds later than planned, and 0.6 meters per second faster than predicted. The S-II stage followed the Skylab into Earth orbit. Skylab’s orbit was almost perfectly circular, with an apogee of 234.2 nautical miles (433.7 kilometers), and perigee of 233.0 nautical miles (431.5 kilometers). The orbital period was 93.23 minutes, with a velocity of 17,111 miles per hour (27,537 kilometers per hour).

Skylab was unmanned at launch. Three 3-man crews were carried to the station aboard Apollo command/service modules launched by the smaller Saturn IB rocket.

Skylab’s mission was to demonstrate that humans could live and work in orbit for extended periods of time, and that they could also perform useful work and research. The first crew had to make repairs in orbit to extend a damaged solar array and to use a spare solar panel as a shade to prevent sunlight from overheating the station. This was the first orbital repair mission. Astronauts occupied Skylab for 171 days, 13 hours and conducted over 300 scientific projects.

The Skylab was built from an empty Saturn V third stage, S-IVB number 213, modified by McDonnell Douglas. The launch vehicle consisted of the first two stages of a Saturn V rocket, an S-IC first stage and an S-II second stage.

The total vehicle weight at engine ignition was 6,297,336 pounds (2,856,424 kilograms). Post-launch analysis determined that the five Rocketdyne F-1 engines of SA-513’s S-IC first stage generated 7,551,000 pounds of thrust (33,588.52 kilonewtons) at Sea Level.

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 (8,200 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 33 feet (10.058 meters) in diameter. Its empty weight was 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).

The S-IC 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, Inc., 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 unmanned space station’s orbit decayed and it reentered on 11 July 1979. It broke up and parts landed in the Indian Ocean and near Perth, Australia.

14 May 1954: The Boeing Model 367-80 prototype, N70700, was rolled out at the Boeing plant at Renton Field, south of Seattle, Washington. Boeing’s founder, William Edward Boeing (1881–1956) was present. The prototype made its first flight 15 July 1954 with Boeing test pilots Alvin M. “Tex” Johnston and Richard L. “Dix” Loesch. It is painted yellow and brown.

Originally planned as a turbojet-powered development of the Boeing KC-97 Stratotanker, the Model 367, the 367-80 was the 80th major design revision. It is called the “Dash 80.”

Boeing had risked $16,000,000 in a private venture to build the Dash 80 in order to demonstrate its capabilities to potential civilian and military customers, while rivals Douglas and Lockheed were marketing their own un-built jet airliners. Put into production as the U.S. Air Force KC-135A Stratotanker air refueling tanker and C-135 Stratolifter transport, a civil variant was also produced as the Boeing 707 Stratoliner, the first successful jet airliner. Though they look very similar, the 707 is structurally different than the KC-135 and has a wider fuselage.

The prototype Boeing Model 367-80 was operated by a pilot, co-pilot and flight engineer. The airplane’s wing was mounted low on the fuselage and the engine nacelles were mounted on pylons under the wing, as they were on Boeing’s B-47 Stratojet and B-52 Stratofortress. The wings and tail surfaces were swept to 35° at 25% chord, and had 7° dihedral. The Dash 80 was 127 feet 10 inches (38.964 meters) long with a wingspan of 129 feet, 8 inches (39.522 meters) and overall height of 38 feet (11.582 meters). The tail span is 39 feet, 8 inches (12.090 meters). The empty weight of the 367-80 was 75,630 pounds (34,505 kilograms) and the gross weight, 190,000 pounds (86,183 kilograms).

N70700 was powered by four Pratt & Whitney Turbo Wasp JT3C engines. This engine is a civil variant of the military J57 series. It is a two-spool, axial-flow turbojet engine with a 16-stage compressor and 2-stage turbine. The JT3C-6 (used in the first production 707s) was rated at 11,200 pounds of thrust (49.82 kilonewtons), and 13,500 pounds (60.05 kilonewtons) with water/methanol injection). The JT3C is 11 feet, 6.6 inches (3.520 meters) long, 3 feet, 2.9 inches (0.988 meters) in diameter, and weighs 4,235 pounds (1,921 kilograms).

These gave the 367-80 a cruise speed of 550 miles per hour (885 kilometers per hour) and a maximum speed of 0.84 Mach (582 miles per hour, 937 kilometers per hour) at 25,000 feet (7,620 meters). The service ceiling was 43,000 feet (13,106 meters). Its range was 3,530 miles (5,681 kilometers).

Boeing continued to use the 367–80 for testing, finally retiring it 22 January 1970. At that time, its logbook showed 2,346 hours, 46 minutes of flight time (TTAF). It was flown to Davis-Monthan Air Force Base, Tucson, Arizona, and placed in storage. In 1990, Boeing returned it to flyable condition and flew it back it to Renton where a total restoration was completed. Many of those who had worked on the Dash 80, including Tex Johnston, were aboard.

The pioneering airplane was presented to the Smithsonian Institution and is on display at the National Air and Space Museum, Steven V. Udvar-Hazy Center. The Boeing 367-80 was designated an International Historic Mechanical Engineering Landmark by the American Society of Mechanical Engineers.

820 of the C-135 series and 1,010 Model 707 aircraft were built from 1957–1979.

11–14 May 1926: The famed Norwegian arctic explorer, Roald Engelbregt Gravning Amundsen, departed Ny-Ålesund, Svalbard, Norway, aboard the semi-rigid airship Norge.

The airship had been designed by Colonel Umberto Nobile and built at the Italian State Airship Factory at Rome, originally named simply N1. In discussions between Amundsen and Nobile, it was determined that N1 was not suitable for an arctic flight. Amundsen didn’t want to wait for a new lighter-than-air craft to be be built, so Nobile modified it. Amundsen purchased N1 and re-named it Norge.

According to an article in the 20 March 1924 edition of Flight, the airship was 106 meters (347 feet, 8 inches) in length, 26 meters (85 feet, 3 inches) in height, with a maximum diameter of 19.5 meters (64 feet). Buoyancy was provided by 19,000 cubic meters (670,700 cubic feet) of hydrogen. The airship had a useful load of 10,850 kilograms (10.5 tons). Its maximum speed was 100 kilometers per hour (62 miles per hour).

Norge was propelled by three water-cooled, normally-aspirated 23.093 liter (1,409.225 cubic inch) Maybach-Motorenbau GmbH Mb.IV inline six-cylinder overhead valve (OHV) engines with four valves per cylinder and a compression ratio of 6.88:1. The engine was able to produce 240 pferdstarke (236.7 horsepower) at 1,400 r.p.m. The engines were placed in gondolas suspended by cables under the hull, and drove propellers through a clutch. A reverse gear was available.

With a 16-man expedition and Umberto Nobile as pilot, Amundsen departed Ny-Ålesund at 9:55 a.m., enroute to Nome, Alaska, via the North Pole. Norge arrived at the Pole at 1:25 a.m. GMT, 12 May, and descending to an altitude of 300 feet (91 meters), dropped three flags, Norwegian, Italian and American, then proceeded south to Alaska. The explorers arrived at Teller at 3:30 a.m., 14 May, and due to adverse weather conditions, ended their flight at that location. Norge had covered 3,393 miles (5,460.5 kilometers).

Amundsen’s flight began just two days after that of Richard E. Byrd and Floyd Bennett aboard their Fokker F.VII/3m, Josephine Ford. Byrd’s flight has been the subject of some controversy as to whether they actually had arrived at the North Pole. The flight of Norge is undisputed.

14 May 1908: Charles William Furnas, a mechanic for the Wright Company, was the first passenger to fly aboard an airplane.

At the Kill Devil Hills, Kitty Hawk, North Carolina, Furnas rode aboard the Wright Flyer III with Wilbur Wright as pilot. The flight covered approximately 600 meters (656 yards) and lasted for 29 seconds. Later the same day, Orville Wright flew the airplane, again with Charley Furnas aboard, this time covering 2.125 miles (3.42 kilometers) in 4 minutes, 2 seconds.

Charles William Furnas was born at Butler Township, Montgomery County, Ohio, 20 December 1880. He was the second of three sons of Franklin Reeder Furnas, a farmer, and Elizabeth J. Rutledge Furnas.

Furnas enlisted in the United States Navy at Dayton, Ohio, 15 November 1902, and was discharged at New York City, 14 November 1906.

Furnas, a machinist, married Miss Lottie Martha Washington, 3 June 1913.

Mrs. Furnas died 1 January 1931. On 30 January 1931, Charles Furnas was admitted to a Veterans Administration Facility in Jefferson Township, Montgomery County, Ohio, where he would remain for the rest of his life.

Charles Furnas died at the Veterans Administration Hospital, Dayton, Ohio, at 9:00 a.m., 15 October 1941. His remains were interred at the Woodland Cemetery and Arboretum, Dayton.

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 Verret (Gondolier)

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).
