27 June 1988: During flight testing of the first Boeing 747-400 airliner, N401PW, serial number 23719, test pilots James C. Loesch and Howard B. Greene took off from Moses Lake, Washington and climbed to an altitude of 2,000 meters (6,562 feet). The total weight of the airplane was 405,659 kilograms (894,325 pounds). This set a new Fédération Aéronautique Internationale (FAI) World Record for Greatest Mass Carried to a Height of 2,000 Meters.¹

The 747-400 was a major development of the 747 series. It had many structural and electronics improvements over the earlier models, which had debuted 18 years earlier. New systems, such as a “glass cockpit”, flight management computers, and new engines allowed it to be flown with a crew of just two pilots, and the position of Flight Engineer became unnecessary. The most visible features of the –400 are its longer upper deck and the six-foot tall “winglets” at the end of each wing, which improve aerodynamic efficiency be limiting the formation of wing-tip vortices. At the time of its first flight, Boeing had already received orders for 100 747-400s. It would become the most popular version, with 694 aircraft built by the time production came to an end 15 March 2007.

The Boeing 747-400 airliner can carry between 416 and 524 passengers, depending on configuration. It is 231 feet, 10 inches (70.663 meters) long with a wingspan of 211 feet, 5 inches (64.440 meters) and overall height of 63 feet, 8 inches (19.406 meters). Empty weight is 394,100 pounds (178,761 kilograms). Maximum takeoff weight (MTOW) is 875,000 pounds (396,893 kilograms). While the prototype was powered by four Pratt and Whitney PW4056 turbofan engines, production airplanes could be ordered with PW4062, General Electric CF6 or Rolls-Royce RB211 engines, providing thrust ranging from 59,500 to 63,300 pounds. The –400 has a cruise speed of 0.85 Mach (567 miles per hour, 912 kilometers per hour) and maximum speed of 0.92 Mach (614 miles per hour, 988 kilometers hour). Maximum range at maximum payload weight is 8,355 miles (13,446 kilometers).

After the test program was completed, the prototype 747-400 was outfitted for airline service configured as a 747-451. It was operated by Northwest Airlines and Delta Air Lines. It was been re-registered as N661US, and carries the Delta fleet number 6301.

25 June 1919

First flight of the Junkers F.13 at Dessau, Germany, 25 June 1919. (Junkers)

25 June 1919: Junkers Flugzeugwerke Aktiengesellschaft test pilot Emil Monz made the first flight of the Junkers F.13 at Dessau, Saxony-Anhalt, Germany. It was the first airplane to be built of all-metal construction specifically for commercial passenger service. The the first flyable prototype, constructor’s number (c/n) 533, carried the identification mark D 183. Professor Junkers had named the airplane Herta in honor of his oldest daughter.¹

Up to this time, airplanes had been primarily constructed of wood. Wood is susceptible to changes in dimension because of temperature and humidity, and it can warp over time. This effects the flight characteristics of the aircraft. Wood is also vulnerable to termites.

By building the airplane of metal, a much more rigid structure was created. The airplane’s flight characteristics did not change over time. Also, because metal is so much stronger than wood, an all-metal airplane could be significantly lighter than one built of wood.

Designed by Chief Engineer Otto Reuter, the F.13 was a single-engine, low-wing monoplane (tiefdecker) with a corrugated duralumin skin over a duralumin structure. It had a flight crew of two and four passengers could be carried in a comfortable enclosed cabin of the same size as automobiles of the time. The single wing was cantilevered and, unusually for the time, used no braces or support wires.

The prototype had a wingspan of 14.47 meters (47 feet, 5.7 inches). The wingspan was increased to 14.82 meters (48 feet, 7.5 inches) in production airplanes. The airplane was 9.59 meters (31 feet, 5.6 inches) long and 4.10 meters (13 feet, 5.4 inches) high. It had a maximum takeoff weight of 1,800 kilograms (3,968 pounds).

The first F.13 was powered by a water-cooled, normally-aspirated 14.778 liter (901.81 cubic inch) Daimler Motoren Gesellschaft Mercedes D.IIIa vertical inline six-cylinder engine. This was a single overhead cam right-hand tractor direct-drive engine. It used two valves per cylinder and a compression ratio of 4.64:1. It produced 174 horsepower at 1,400 r.p.m., and drove a two-bladed, fixed-pitch laminated wood propeller. The D.IIIa weighed 660.0 pounds (299.4 kilograms), including the propeller hub and exhaust manifold.

Production airplanes used BMW and Junkers engines.

The F.13 had a maximum speed of 170 kilometers per hour (106 miles per hour).

In production from 1919 to 1932, a total of 332 Junkers F.13s were built. Some remained in service in the late 1930s.

In 1920, D 183 was confiscated by the Inter-Allied Control Commission. Later, the F.13 flew for Lufthansa. The registration mark was changed to D 1 and it was named Nachtigall (Nightingale).

Emil Monz

Emil Monz was born 9 June 1893, in Stuttgart, Germany. He was the son of Karl and Mathilde Monz. He married Fräulein Maline Georgine Erhardt, 24 January 1915, at Weingarten u. Wilhelmsdorf, Württrmberg, Deutschland.

During World War I, Monz was a reconnaissance pilot for the German Empire.

On 13 September 1919, Monz flew the second F.13, with seven passengers on board, to an altitude of 6,750 meters (22,146 feet). This was an unofficial world record.

Emil Monz died 18 February 1921 when the Junkers F.13 that he was flying, D 128, crashed in a snowstorm enroute to Stuttgart.

¹ While it is believed that Professor Junkers named the prototypes after his daughters Herta and Annelise, sources vary over which name was applied to which aircraft. The confusion may be a result of the serial numbers. The first F.13 to fly was c/n 533, while the second had an earlier number, c/n 531.

24 June 1982: British Airways Flight 9, a Boeing 747-236B, G-BDXH, City of Edinburgh, enroute from London, England, to Aukland, New Zealand, was cruising at 37,000 feet (11,278 meters) with 248 passengers and 15 crewmembers on board. The airliner was under the command of Captain Eric H. J. Moody, with Senior First Officer Roger Greaves and Senior Flight Engineer Barry Townley-Freeman on the flight deck. It operated with the call sign, “Speedbird 9.”

At 10:42 p.m., local time (13:42 UTC), approximately 110 miles (188 kilometers) south of Jakarta, Indonesia, the airliner’s number four engine began surging and then flamed out. A minute later engine number two also surged and flamed out. Then, simultaneously, engines one and three failed as well.

Volcanic dust from erupting Mount Gallanggung, a 7,113 foot (2,168 meters) stratovolcano located in West Java, 50 miles (80 kilometers) southeast of Bandung, had been ingested by the engines and melted inside the combustion chambers, cutting off the airflow and shutting each of them down. The 747 had a glide ratio of 15:1. The flight crew turned Speedbird 9 toward Jakarta while they went through emergency procedures.

Captain Eric Moody made the following announcement to the passengers:

“Ladies and gentlemen, this is your captain speaking. We have a small problem. All four engines have stopped. We are doing our damnedest to get them going again. I trust you are not in too much distress.”

At 13,500 feet (4,115 meters), the flight crew was finally able to get one engine restarted and soon after, a second. Eventually all four engines were running and the 747 began to regain altitude. The Number Two engine again began to surge so the crew shut it down and the 747 remained at 12,000 feet (3,658 meters).

On approach to Jakarta, though good visibility was reported, the flight crew could barely see the airport lights. It was later determined that the windshield was completely sandblasted by the volcanic dust. Speedbird 9 safely landed with no injuries. Captain Moody later said, “The airplane seemed to kiss the earth and we were on the ground safely.”

G-BDXG was repaired and flown back to London, where it underwent further, more extensive repairs.

Captain Moody and Senior Cabin Services Officer Graham Skinner were awarded the Queen’s Commendation for Valuable Service in the Air. Guinness Book of Records lists Flight 9 as the longest glide of any aircraft not designed for gliding.

24 June 1939: The Pan American Airways System began scheduled air service from the United States to Britain. The Boeing 314 Yankee Clipper, NC18603, made the first flight from Port Washington, New York, departing at 8:21 a.m. It made intermediate stops at Shediac, New Brunswick, and Botwood, Newfoundland, where fog delayed the flying boat until 12:49 p.m., 28 June. Continuing across the Atlantic, Yankee Clipper made another stop at Foynes, Ireland, and finally arrived at Southampton at 7:25 p.m. that evening.

The largest airplane of the time, the Pan American Clipper flying boat could carry 77 passengers in “one class” luxury, with a ticket priced at $675—that’s in 1939 dollars. ($12,217.50 in 2018) Uniformed waiters served five and six course meals on silver service. Seats could be folded down into beds.

The Boeing Model 314 was a large four-engine, high-wing monoplane flying boat designed and built by the Boeing Airplane Company to take off and land on water. It had a crew of 10. The wings and engine nacelles had been designed for Boeing XB-15 heavy bomber. It was 106 feet (32.309 meters) long with a wingspan of 152 feet (46.330 meters). It had a maximum take off weight of 82,500 pounds (37,421 kilograms).

The Boeing 314 was powered by four air-cooled, supercharged, 2,603.737-cubic-inch-displacement (42.668 liter) Wright Aeronautical Division Cyclone 14 GR2600A2, two-row, 14-cylinder radial engines with a compression ratio of 7.1:1. They were rated at 1,200 horsepower at 2,100 r.p.m., and 1,550 horsepower at 2,400 r.p.m. for takeoff, burning 91/96 octane gasoline. These engines (also commonly called “Twin Cyclone”) drove three-bladed Hamilton Standard Hydromatic full-feathering constant-speed propellers with a diameter of 14 feet (4.267 meters) through a 16:9 gear reduction. The GR2600A2 was 5 feet, 2.06 inches (1.576 meters) long and 4 feet, 7 inches (1.387 meters) in diameter. It weighed 1,935 pounds (878 kilograms). The engines could be serviced in flight, with access through the wings.

The Boeing 314 had a maximum speed of 199 miles per hour (320 kilometers per hour), with a  range of 3,685 miles (5,930 kilometers) at its normal cruising speed of 183 miles per hour (295 kilometers per hour). Its service ceiling was 13,400 feet (4,084 meters). The fuel capacity was 4,246 gallons (16,073 liters).

Boeing built six Model 314 and another six 314A flying boats for Pan American Airways and British Overseas Airways Corporation.

Yankee Clipper was destroyed 22 February 1943 at Lisbon, Portugal. A wing hit the water on landing. 24 of the 39 persons aboard were killed.

16 June 1984: Frontier Airlines Flight 244, a Boeing 737, flies from Stapleton Airport, Denver, Colorado (DEN) to Lexington, Kentucky (LEX). In the cockpit were Captain Emily H. Warner and First Officer Barbara Cook. This was the very first time that an all-woman flight crew flew a scheduled route for a U.S. airline. The cabin crew for the flight were Tim Griffin, Mark Becker and Ashley McQueen.

The Chicago Tribune reported:

Women pilot flight into airline history

DENVERFrontier Airlines teamed the first woman pilot hired by a major airline with a woman copilot Saturday for a flight from Denver to Lexington, Ky., in what one official said was the first all-female crew in commercial airline history. A spokesman for Denver-based Frontier official said the airline did nothing special to bring Capt. Emily Warner of Denver together with First Officer Barbara Cook of Denver. “That’s just the way the rotation came up,” he said. Warner, who became the first woman hired by a major airline when she joined Frontier in 1973, said of the flight: “I feel good about it. I figured I’d be flying with a gal one of these days.”

Emily Hanrahan Howell Warner was hired by Frontier Airlines as a second officer in 1973, and is considered to be the first woman to be hired as a pilot for a U.S. commercial airline. After her first revenue flight, she received a bouquet of red, white and blue flowers from Captain Turi Widerøe of Scandanavian Airlines System (SAS), who was the world’s first woman airline captain. In 1976, Emily Warner was promoted to captain, the first woman to hold that rank with an American airline.

The Boeing 737-200 series was a short- to medium-range, narrow body, twin-engine civil transports. The -200 first flew 8 August 1967. It had a flight crew of two and could carry a maximum of 136 passengers.

The 737-200 is 100 feet, 2 inches (30.531 meters) long with a wingspan of 93 feet, 0 inches (28.346 meters) and overall height of 36 feet, 10 inches (11.227 meters). Flight 243’s actual takeoff weight was 93,133 pounds (42,224 kilograms). (Its maximum certificated takeoff weight was 100,000 pounds (45,359 kilograms).

The airliner was powered by two Pratt & Whitney JT8D-9A low-bypass turbofan engines producing 14,500 pounds of thrust, each. The 737-200 had a cruise speed of 0.74 Mach (489 miles per hour, 787 kilometers per hour) and a maximum speed of 0.82 Mach (542 miles per hour/872 kilometers per hour). The service ceiling was 35,000 feet (10,668 meters).

1,010 Boeing 737–200s were built. The last one in service with an American airline was retired 21 March 2008.
