Frank Monroe Hawks, 1932 (Edward Steichen)

13 August 1930: Frank Monroe Hawks flew from Grand Central Air Terminal in Glendale, California, to Curtiss Airport, Valley Stream, Long Island, New York, in a record-breaking elapsed time of 12 hours, 25 minutes, 3 seconds. His airplane was a Travel Air Type R “Mystery Ship” named Texaco No. 13. It carried civil registration NR1313.

Hawks departed Glendale (a suburb adjacent to the City of Los Angeles) at 2:16:27 a.m., Pacific Standard Time (09:16 G.M.T.). The takeoff was timed by J.A. Nikrent of the American Aeronautical Association. He flew to Albuquerque, New Mexico, a distance of 665 miles (1,070 kilometers), where he stopped to refuel at 6:43 a.m., Mountain Standard Time (12 :43 G.M.T.) 17 minutes later, at 9:00 a.m., (13:00 G.M.T.), he was airborne. The next stop for the “Mystery Ship” was Wichita, Kansas, 540 miles (869 kilometers). He landed at 10:28 a.m., Central Standard Time (15:28 G.M.T.) and took off again at 10:35 a.m., after just 7 minutes on the ground. The next fuel stop was Mars Hill Airport at Indianapolis, Indiana. After a flight of 600 miles (966 kilometers), he arrived there at 1:23 p.m., C.S.T. (18:23 G.M.T.) At 1:36 p.m., Hawks took off on the final leg, a distance of 705 miles (1,135 kilometers).

Hawks landed at Curtiss Field at 5:41:30 p.m., Eastern Standard Time (21:41 G.M.T.) The total flight time was 11 hours, 48 minutes, 3 seconds. He broke the previous record, set by Charles Lindbergh, by 2 hours, 20 minutes, 29 seconds.

One week earlier, 6 August 1930, Hawks had flown across the continent from east to west, in 14 hours, 50 minutes 3 seconds. More favorable winds allowed the Type R to make a faster west-to-east flight.

Hawks’ Texaco No. 13 was the fourth of five specially designed and constructed racing aircraft produced by Travel Air Manufacturing Company of Wichita, Kansas. The company was founded by Walter Beech, Clyde Cessna, and Lloyd Stearman. The “Type R” refers to one of its designers, Herb Rawdon.

The Type R was a low-wing monoplane with a fuselage constructed of welded tubular steel covered with plywood. The very thin wing was braced by wires. It used spruce spars and ribs. Both fuselage and wings were covered with 1/16-inch mahogany plywood. Attempts to streamline the airplane included a raised profile behind the pilot’s head, “wheel pants,” as well as a NACA-designed engine cowling that provided better engine cooling and caused less aerodynamic drag.

The Travel Air Type R was 20 feet, 2 inches (6.147 meters) long, with a wingspan of 30 feet, 0 inches (9.144 meters) and overall height of 7 feet, 9 inches (2.362 meters). The wing had a chord of 5 feet, 0 inches (1.524 meters), and total area of 125 square feet (11.6 square meters). It had an empty weight of 2,000 pounds (907 kilograms) and gross weight of 3,300 pounds (1,497 kilograms).

The Mystery Ship was powered by an air-cooled, supercharged, 971.930-cubic-inch-displacement (15.927 liter) Wright Aeronautical Division Whirlwind Nine (also known as the J-6-9 or R-975) nine-cylinder radial engine, normally rated at 300 horsepower at 2,000 r.p.m. Various sources state that Hawks’ R-975 had been modified by increasing its compression ratio and supercharger speed, and that it produced 450 horsepower at 2,400 r.p.m. The R-975 was built in both direct drive and geared versions. The two-bladed Standard Steel propeller had a diameter of 8 feet, 0 inches (2.438 meters).

The Mystery Ship’s cruising speed was 200 miles per hour (322 kilometers per hour) at 1,950 r.p.m., and it had a maximum speed of 250 miles per hour (402 kilometers per hour) at Sea Level. It had an initial rate of climb of 3,200 feet per minute (16.26 meters per second). The service ceiling was 30,000 feet (9,144 meters) and the absolute ceiling was 31,000 feet (9,449 meters). The range at cruise speed was 1,000 miles (1,609 kilometers).

One of the fastest airplanes of its time, the Type R set over 200 speed records.

Newspapers called the Type R airplanes “mystery ships” because Beech was very secretive about them. When two of them were flown to the 1929 National Air Races at Cleveland, Ohio, they taxied directly to a hangar and shut off their engines. They were immediately pushed inside. The hangar was kept locked and under guard.

Frank Hawks was an Air Service, United States Army, pilot who served during World War I. He rose to the rank of Captain, and at the time of his record-breaking transcontinental flight, he held a commission as a reserve officer in the Army Air Corps. His flying had made him a popular public figure and he starred in a series of Hollywood movies as “The Mystery Pilot.”

Frank Hawks’ Type R is in the collection of the Museum of Science and Industry, Chicago, Illinois.

Lieutenant Harvey-Kelly
Lieutenant Hubert Dunsterville Harvey-Kelly, D.S.O., Royal Flying Corps.

13 August 1914: Lieutenant Hubert Dunsterville Harvey-Kelly, No. 2 Squadron, Royal Flying Corps, departed Dover at 6:25 a.m., 13 August 1914, enroute to Amiens, France. He flew a Royal Aircraft Factory B.E.2.a, number 471. Landing near Amiens at 8:20 a.m., this was the first British airplane to arrive in France following the outbreak of World War I.

Hubert Dunsterville Harvey-Kelly was born at Berry Pomeroy, Devon, 9 February 1891. He was one of five children of Colonel Harvey Hamilton Harvey-Kelly, Indian Staff Corps, and Constance J. Dunsterville Harvey-Kelly. (They were married at Hyderabad, Siad, 15 December 1877.) He attended the Modern School, and the Royal Military College at Sandhurst. On graduation, Harvey-Kelly received a commission as a second lieutenant in the Royal Irish Regiment, 5 October 1910. He was promoted to lieutenant, 23 October 1912.

After learning to fly, Lieutenant Harvey-Kelly received the Royal Aero Club aviator’s license number 501, issued 30 May 1913. At his own request, Harvey-Kelly was then attached to the Royal Flying Corps, as a Lieutenant, R.F.C. Reserve, 14 August 1913.

Lieutenant Harvey-Kelly was created a Companion of the Distinguished Service Order, 18 February 1915, and promoted to captain, 23 May 1915. On 30 January 1916, Captain Harvey-Kelly was promoted to the temporary rank of major.

In command of No. 19 Squadron, R.F.C., Major Dunston was flying a SPAD S.VII C.1 when he was shot down 25 April 1917 by Oberleutnant Kurt Robert Wilhelm Wolff, flying an Albatros D.III. Severely injured, he died in a German field hospital, 29 April.

Major Hubert Dunsterville Harvey-Kelly, D.S.O., Royal Irish Regiment (attd. Royal Flying Corps) was buried at Brown’s Copse Cemetery, northwest of Roeux, Pas-de-Calais, France.

Royal Aircraft Factory B.E.2.a number 471 had been built by the Coventry Ordnance Works and delivered to the Royal Flying Corps at Farnborough, 5 June 1913. It had initially been assigned to the Central Flying School before being transferred to No. 2 Squadron.

The Royal Aircraft Factory B.E. (which stands for Blériot Experimental, meaning that it was a tractor-type airplane, which had been developed by Louis Blériot) was designed by Geoffrey de Havilland. It was a two-place, single-engine, two-bay biplane which was used as a trainer, reconnaissance aircraft, artillery spotter or bomber. An observer occupied the forward cockpit and the pilot was aft.

The B.E.2.b was essentially the same as the B.E.2.a, except the cockpit sides were higher. The elevator control cables were external from the pilot’s cockpit, aft. Probably the most significant change was the use of ailerons for the B.E.2.b, where the previous versions had used wing-warping like the original 1903 Wright Flyer.

The fuselage was constructed of a wooden framework, cross-braced with wires. The wings had wood spars and ribs. The airframe was covered in doped fabric.

The wings of the 2.a and 2.b were straight with no dihedral. Both upper and lower wings had the same span and chord, and were not staggered. (The B.E.2.c added both dihedral and stagger.) The lower wing spars were connected through the fuselage with steel tubing. The landing gear had both wheels and tires, but also wood-covered steel tube skids extending forward to protect the propeller from contacting the ground.

The B.E.2.a–2.b was 29 feet, 6½ inches (9.004 meters) long with a wingspan of 38 feet, 7½ inches (11.773 meters). The wings’ chord was 6 feet, 4 inches (1.930 meters). It had an empty weight of 1,274 pounds (578 kilograms) and gross weight of 1,600 pounds (726 kilograms).

The B.E.2, B.E.2.a and B.E.2.b were powered by an air-cooled, normally-aspirated 6.949 liter (424.036 cubic inch) Renault Type WB side-valve 90° V-8 engine with two valves per cylinder and a compression ratio of 4.12:1. The WB was rated at 70 horsepower at 1,750 r.p.m. The engine drove a four-bladed, fixed-pitch wooden propeller at one-half crankshaft speed. The Renault WB was 3 feet, 9.5 inches (1.556 meters) long, 2 feet, 8.8 inches (0.833 meters) high and 2 feet, 5.8 inches (0.757 meters) wide. It weighed 396 pounds (180 kilograms).

The airplane had a maximum speed of 70 miles per hour (113 kilometers per hour) at Sea Level and 65 miles per hour (105 kilometers per hour) at 6,500 feet (1,981 meters). It could climb to 3,000 feet (914 meters) in 9 minutes and to 7,000 feet (2,134 meters) in 35 minutes. The service ceiling was 10,000 feet (3,048 meters). Maximum endurance was 3 hours.

The B.E.2.b was unarmed. The crew could only defend themselves with their personal weapons. The type was easy prey for German fighters. It could carry a small bomb.

Although designed by the Royal Aircraft Factory, Farnbourough, only 6 B.E.2s were built there. The remainder were built by Armstong Whitworth, British and Colonial Airplane Co., Coventry Ordnance Works, Handley Page, Hewlett and Blondeau, and Vickers. Eighty-five of the B.E.2.b variant were produced, with most being used as trainers. Nineteen were sent to the Expeditionary Force in France, and one to the Middle East Brigade. By late 1915, the type had been almost completely replaced by the improved B.E.2.c.

Japan Air Lines’ Boeing 747-146SR, JA8119. (Robin787)

12 August 1985: The worst accident involving a single aircraft occurred when a Boeing 747 operated by Japan Air Lines crashed into a mountain in the Gunma Prefecture, killing 520 persons. There were just 4 survivors.

JAL Flight 123 was a Boeing 747-146SR, registration JA8119. It departed Tokyo International Airport enroute Osaka International Airport. There were 15 crewmembers, led by Captain Masami Takahama, with First Officer Yutaka Sasaki and Second Officer Hiroshi Fukuda. There were 509 passengers aboard.

Flight 123 lifted off at 6:12 p.m., 12 minutes behind schedule. 12 minutes after takeoff, as the 747 was at its cruising altitude, the fuselage rear pressure bulkhead suddenly failed, causing explosive decompression of the cabin. Cabin air then rushed into the unpressurized tail section. The resulting overpressure caused a failure of the APU bulkhead and the support structure for the vertical fin. The airliner’s vertical fin separated from the fuselage. All four of the 747’s hydraulic systems were ruptured. The hydraulic system was quickly depleted, leaving the crew unable to move any flight control surfaces.

Control of the airplane began to quickly deteriorate and the only control left was to vary the thrust on the four turbofan engines. The flight crew began an emergency descent and declared an emergency.

For the next 32 minutes, JA8119 flew in large uncontrolled arcs. The 747 rolled into banks as steep as 60°, and at one point, the nose pitched down into a dive reaching 18,000 feet per minute (91 meters per second). The crew was able to bring the 747 back to a nose-high attitude at about 5,000 feet (1,524 meters), but again lost control. At 6:56 p.m., JAL 123 disappeared from air traffic control radar.

The airliner struck a ridge on 1,978.6 meter (6,491.5 feet) Mount Takamagahara at 340 knots (391 miles per hour, or 630 kilometers per hour), then impacted a second time at an elevation of 5,135 feet (1,565 meters). The aircraft was totally destroyed.

The four survivors had been seated in the last three rows of the airliner, though their exact seat assignments have not been determined. Several others actually survived the impact but died from their injuries and exposure before they could be rescued.

Investigation of the accident determined that the 747 had previously been damaged when its tail struck the runway during a landing, 2 June 1978. The rear pressure bulkhead had cracked as a result of the tail strike, but was repaired by a team of Boeing technicians. After the crash, it was discovered that the repair had not been correctly performed. Boeing engineers calculated that it could be expected to fail after 10,000 cycles. It was on the 12,219th cycle when the bulkhead failed.

Boeing 747-146SR JA8119 had accumulated a total of 25,030 flight hours by the time of the accident, on 18,835 flights.

12 August 1960: At Edwards Air Force Base, California, Major Robert M. White flew the North American Aviation X-15 rocketplane to an altitude of 136,500 feet (41,605 meters), exceeding the previous unofficial record of 126,200 feet (38,466 meters) set by the late Captain Iven C. Kincheloe, Jr., with the Bell X-2, 7 September 1956.

Iven Kincheloe had been assigned as the Air Force’s project pilot for the X-15. When he was killed on a routine flight, Bob White was designated to replace him.

This was White’s fourth flight in an X-15, and the 19th flight of the X-15 Program. The Number 1 rocketplane, serial number 56-6670, was carried aloft under the right wing of the “mothership,” Boeing NB-52A Stratofortress 52-003. At 08:48:43.0 a.m., PDT, 56-6670 was dropped over Silver Lake, near the Nevada-California border. White fired the two Reaction Motors XLR11-RM-13 rocket engines and they burned for 256.2 seconds.

This flight took place in Phase II of the Program and was intended to gradually increase the envelope of X-15 performance with the XLR11 engines while waiting for the much more powerful XLR99. The purpose of Flight 19 was to reach maximum altitude in order to test the rocketplane’s stability and controllability above the atmosphere.

The X-15 accelerated to Mach 2.52, 1,773 miles per hour (2,853 kilometers per hour) while climbing at nearly a 70° angle and reached a peak altitude of 136,500 feet (41,605 meters). After engine shutdown, White glided to a landing on Rogers Dry Lake and touched down. The duration of the flight was 11 minutes, 39.1 seconds.

Neither Kincheloe’s or White’s altitudes are recognized as records by the Fédération Aéronautique Internationale(FAI). Over the next few years, the X-15 would reach to nearly three times higher.

Signal Corps Dirigible No. 1 at Fort Myer, Virginia, 1908 (U.S. Army)

12 August 1908: Test flights begin for Signal Corps Dirigible No. 1 at Fort Myers, Virginia, with Thomas Scott Baldwin as pilot and Glenn Hammond Curtiss as flight engineer.

Brigadier General James Allen, Chief Signal Officer, 1906–1913. (U.S. Army)

On 1 August 1907, Brigadier General James Allen, Chief Signal Officer, United States Army, issued a directive establishing the Aeronautical Division within the Signal Corps. Captain Charles Chandler was the officer in charge. Specifications were published in Signal Corps Bulletin No. 5, soliciting bids for both lighter- and heavier-than air vehicles. There were 41 responses. Plans were submitted and a board of officers selected plans for those that seemed most practical.

The lighter-than-air craft was required to be a self-propelled dirigible (a “directable” balloon) able carry two persons and to be able to travel at 20 miles per hour (32.2 kilometers per hour). Thomas Scott Baldwin’s proposal was selected. (The Wright brothers’ Military Flyer was selected as the heavier-than-air winner on 2 August 1909, and designated Signal Corps Airplane No. 1.)

On 3 August 1908, Baldwin No. 8 was presented to the Army for trials. Although the the Baldwin No. 8 reached an average speed of just 19.61 miles per hour (31.56 kilometers per hour). It demonstrated the required endurance of two hours, averaging 14 miles per hour (22.5 kilometers per hour). Although the airship’s speed was short of the requirement, on 5 August, the Army purchased it from Baldwin for $5,737.59. The airship was designated Signal Corps Dirigible No. 1.

Contemporary sources give the airship’s dimensions as being 96 feet (29.26 meters) long with a maximum diameter of 19 feet, 6 inches (5.94 meters). The envelope was made of two layers of silk fabric separated by a layer of vulcanized rubber, and supported by 30 wooden frames. Buoyancy was provided by hydrogen gas. The envelope’s volume was approximately 20,000 cubic feet (566 cubic meters).

An open girder beam gondola (or “car”) built of spruce was suspended beneath the balloon. The gondola was 66 feet (20.12 meters) long with a  2½ feet × 2½ feet (0.76 × 0.76 meters) cross section. A water-cooled Curtiss-built inline four-cylinder gasoline engine was mounted at the front end of the gondola. The engine produced 20 horsepower and drove the tractor propeller through a steel drive shaft at 450 r.p.m. The two-bladed spruce propeller had a diameter of 10 feet, 8 inches (3.25 meters) and pitch of 11 feet (3.35 meters).

A two-plane “box-kite” canard elevator unit behind the engine provided control for pitch. The pilot was located behind the control surfaces. Another crew member was at the rear of the gondola, followed by a fixed cruciform stabilizer unit.

The dirigible had a lifting capacity of  1,350 pounds (612.4 kilograms). The payload was 500 pounds (226.8 kilograms).

The U.S. Army’s first aviators, Lieutenants Benjamin D. Fulois, Thomas Etholen Selfridge and Frank P. Lahm were taught to fly the airship. Lahm and Fulois made the first flight of an all-Army crew on 26 August.

Signal Corps Dirigible No. 1 was assigned to the Signal Corps Post at Fort Omaha, Nebraska, where the Army had a balloon factory. It was operated there until 1912. The airships envelope needed to be replaced, and unwilling to spend money for that, the airship was sold.
