Breguet Br.19 TF Super Bidon Point d’Interrogation
1 September 1930: At 10:54 a.m., local time (09:54 G.M.T.), Dieudonné Costes and Maurice Bellonte ¹ took off from the Aéroport de Paris – Le Bourget, in a red Breguet Br.19 TF Super Bidon. Their destination was New York, non-stop across the North Atlantic Ocean. At 6:12:30 p.m., Eastern Daylight Time, 2 September (22:12:30 G.M.T.), they landed at Curtiss Field, Valley Stream, Long Island, New York. The two aviators had flown 5,913 kilometers (3,674 statute miles, 3,193 nautical miles) in a total elapsed time of 37 hours, 18 minutes, 30 seconds.
“Solid black line shows the course that Costes and Bellonte took from Paris. The broken line is the famous Lindbergh route.” (The Brooklyn Daily Times, Wednesday, 3 September 1930, Page 3, Columns 4–6)
More than 25,000 people, including Charles A. Lindbergh, were waiting at Valley Stream to welcome the two French aviators to America.
Breguet Br.19 TF Super Bidon Point d’Interrogation
The Breguet Br.19 TF Super Bidon was named Point d’Interrogation (“Question Mark”—?), because one of the flight’s sponsors—the Coty fragrance company—was a mystery. The airplane is a single-engine, two-place sesquiplane: a biplane with the span of the lower wing substantially shorter than the upper. It was a specially-built long-distance racer which had made its first flight two years earlier, on 23 July 1928. Since then it had been modified from the original TR configuration by lengthening the fuselage, increasing the wing span and the vertical gap between the wings, and increasing the fuel capacity.
The Br.19 TF was 10.718 meters (35 feet, 1.2 inches) long, with an upper wingspan of 18.300 meters (60 feet, 0.5 inches) and lower span of 11.496 meters (37 feet, 8.6 inches). The airplane’s height was 4.080 meters (13 feet, 4.6 inches). The total wing area was 61.940 square meters (666.717 square feet). The Super Bidon had an empty weight of 2,190 kilograms (4,828 pounds) and gross weight of 6,375 kilograms (14,054 pounds).
Costes and Bellonte at Boston, 1930 (Leslie Jones Collection, Boston Public Library)
Two main fuel tanks were placed between the engine and the crew’s cockpits. The tanks’ walls made up the fuselage surface in that area. The total fuel capacity was 5,570 liters (1,471 U.S. gallons), with two additional 166 liter (44 gallon) jettisonable tanks located under the lower wing. (These were removed just prior to takeoff.) The engine was provided with 220 liters of lubricating oil.
The Br.19 TF was powered by a liquid-cooled, normally-aspirated, 36.050 liter (2,199.892-cubic-inch-displacement) Société Française Hispano-Suiza 12Nb single-overhead-cam (SOHC) 60° V-12 engine, which produced 650 cheval-vapeur (641 horsepower) at 2,100 r.p.m. The direct-drive V-12 turned a two-bladed metal propeller.
The Super Bidon has a maximum speed of 250 kilometers per hour (155 miles per hour), and range of 6,700 kilometers (4,163 statute miles).
¹ Paris, Sept 1 (U.P.)—Dieudonné Coste and the Air Ministry have disagreed over the proper way to spell the famous flyer’s name.
Not long ago the flyer said he preferred to spell his name “Coste,” dropping the final”s.” which he used until a year ago. He signed autographs without the final “s” before departing for New York. The Air Ministry insisted, however, that the official spelling is “Costes.”
Coste’s name is pronounced to rhyme with “lost,” making the final letter silent.
Bellonte’s name is pronounced “Bell-ont,” to rhyme with “jaunt.”
America’s first woman airplane pilot, Blanche Stuart Scott. The aircraft is a Curtiss Model D. (George Grantham Bain Collection, Library of Congress)
2 September 1910:¹ After receiving flight instruction from Glenn Hammond Curtiss, Miss Blanche Stuart Scott became the first woman in the United States to fly an airplane when she made a solo flight in a Curtiss biplane at Lake Keuka Field, Hammondsport, New York.
She later wrote:
It was customary in those days to have the student “cut grass” for many days, to become thoroughly familiar with the controls. As the plane was a one seater, no instructor would go along to teach the student. There was a governor on the engine to hold the power down and keep the plane on the ground. My fourth trip down the field “grass cutting” caught a side wind and the plane soared about ten feet in the air. It felt like a hundred feet. Curtiss was alarmed, because at that stage in aviation an injured or killed woman would have been the worst publicity. However, and perhaps because I didn’t know enough to be afraid, I landed safely. Two days later, I asked Curtiss to take the governor off the engine, and he finally agreed. I stepped into the little old 35 hp ship, waved a flippant good-bye and took right off, flew around the field and made a good landing. I have never found that any woman antedated that flight.

She became a professional exhibition pilot and worked for Curtiss as a test pilot—the first woman in that occupation. She is said to have earned as much as $5,000 per week with Curtiss, nearly $133,000 in 2018 U.S. dollars.
On 6 September 1948, Blanche Scott was the first woman to fly in a jet-powered aircraft when she rode with Major Charles E. (“Chuck”) Yeager, U.S. Air Force, in a two-place Lockheed TF-80C Shooting Star (later redesignated T-33A).
Blanche Stuart Scott (NASM)
Blanche Stuart Scott ² was born 8 April 1885 ³ at Rochester, New York. Her father was James C.S. Scott, owner of Scott’s Hoof Paste Co., Inc., of Rochester, and her mother was Belle J. Herendeen Scott. Mr. Scott died in 1904. Mrs. Scott continued to run the business.
Blanche Scott, also known as “Betty,” was educated at Vassar College, a highly-regarded residential school for women in Poughkeepsie, New York.
In April 1910, Blanche Scott was employed as an auto saleslady.
Miss Scott first gained public notice when she drove across the North American continent, departing New York City on 16 May 1910, and arriving at San Francisco, California, on 23 July. She had driven approximately 5,400 miles (8,690 kilometers) in 69 days.
Scott’s automobile was an Overland Model 38 “runabout,” named Miss Overland. It was a front-engine, rear-wheel drive car, with a water-cooled, normally-aspirated 198.804 cubic-inch-displacement Overland inline four-cylinder L-head engine with two valves per cylinder. It used a single Schebler carburetor. The engine produced 25 horsepower. The power was transmitted from a two-speed transmission by a drive shaft to the rear axle. Two wheels were equipped with manual brakes. Goodyear 32″× 3.5″ tires were used on all four wheels. The Model 38 was advertised for sale at $1,095. (Scott was the first woman to make the transcontinental journey from east to west. The previous year, Alice Ramsey, also a Vassar alumni, drove a Maxwell touring car from San Francisco to New York, west-to-east, in 59 days.

Blanche S. Scott married 32-year-old Harry Bronson Tuttle, superintendent of agencies for Willys-Overland Co., (until recently, the head of the service department of the Dayton Motor Car Company) at Detroit, Michigan, 24 October 1910.
On 1 July 1912, Mrs. Tuttle was flying for Glenn L. Martin’s exhibition team, the Martin Flying Circus, at Squantum, Massachussets, and witnessed the death of Harriet Quimby, America’s first licensed female pilot.
Her husband, Harry Tuttle, is reported to have told her, “she must choose at once and for all between him and aviation.”
There marriage soon ended.
Blanche Scott starred as “The Aviator” in “An Aviator’s Success,” and as “Bertha Monroe” in “The Aviator and the Autoist Race for a Bride.” Both silent films were produced by the Champion Film Company and released in 1912.
On Memorial Day, 26 May 1913, Blanche crashed her airplane during an exhibition at Madison, Wisconsin. There are many versions as to what occurred, and as many as to the extent of her injuries.
By 1915, Blanche Scott Tuttle was living with her mother, now running a hotel in Mentz, New York. She listed he occupation as “aviator.”

13 July 1917 Mrs. Tuttle married George K. Hennings, of Philadelphia, at Lake County, Indiana. They eventually separated and she headed west to Hollywood where she became a script writer for R.K.O. Pictures, Universal, and Warner Brothers. She was known for her witty dialogue. George Hennings died in 1941.
In 1921, Blanche Scott was the studio manager for the Hal Benedict Studios at Flushing, New York.
In 1929, the organization Early Birds of Aviation was founded. The membership was limited to pilots who had made their solo flights before 1916. Blanche Stuart was one of the original members.
1931, she joined radio station KFI in Los Angeles as a talk show host. In 1936 Scott returned to Rochester to care for her mother. She worked for several radio stations in the area.

From 1953 to 1958, Ms. Scott was employed as a consultant by the National Museum of the United States Air Force at Wright-Patterson Air Force Base, Dayton, Ohio. She searched for items that the museum could acquire to help tell the history of early aviation.
Blanche Stuart Scott died at Genesee Hospital in Rochester, 12 January 1970. Her remains were interred at the Riverside Cemetery, Rochester, New York.
¹ The actual date of her flight is uncertain. Some sources cite 6 September, while others give a range of from 2 to 12 September.
² Blanche Stuart Scott was also known as Betty Scott, Blanche S. Tuttle and Blanche S. Hennings.
³ Various sources give Ms. Scott’s date of birth as 1880, 1884, and 1889. Social Security Administration records state 1885, which coincides with her age as listed in Federal and New York state censuses from 1900, 1905 and 1915.

1 September 1983: At approximately 1826 hours UTC, Lieutenant Colonel Gennadiy Nikolayevich Osipovich of the V-PVO, (Soviet Air Defence Forces—Войска ПВО, Voyska Protivovozdushnoy Oborony) flying a Sukhoi Su-15TM interceptor, fired two Kaliningrad R-98MR air-to-air missiles at a Korean Air Lines Boeing 747 which was in international air space over the Sea of Japan at an altitude of 35,000 feet (10,668 meters). Both missiles’ 40 kilogram (88 pound) warheads were detonated by proximity fuses 50 yards (45 meters) behind the airliner and blast fragmentation shrapnel caused severe damage.
Over the next twelve minutes, the 747 spiraled downward until it crashed into the Sea of Japan near Moneron Island. All 269 persons on board were killed.
The airliner, KAL Flight 007, had departed Anchorage International Airport en route to Seoul, Republic of Korea. In command was Captain Chun Byung-in. The co-pilot was First Officer Son Dong Hui and the flight engineer was Kim Eui Doing. There were a total of 29 crew members and 240 passengers on board.
After leaving Anchorage airspace, the airplane, a 12-year-old Boeing 747-230B, registration HL7442, continuously deviated to the north of its planned course. The airliner entered Soviet airspace, crossed over the Kamchatka Peninsula, and then flew over Sakhalin Island. Based on these two airspace incursions, the Soviet military chain of command specifically ordered Lieutenant Colonel Osipovich to shoot down the airliner, even if it was over international waters.

It is believed that the KAL 007 flight crew had placed the autopilot in the heading mode when it should have been in the Inertial Navigation Mode. From review of cockpit voice recorder tapes that were later recovered, it is not believed that the crew was ever aware that they were flying north of their course.

When interviewed by The New York Times for the 9 December 1996 edition, Colonel Osipovich, by then retired, said, “I saw two rows of windows and knew this was a Boeing. . . I knew this was a civilian plane. But for me this meant nothing. It is easy to turn a civilian type of plane into one for military use.”

1 September 1974: Major James V. Sullivan, USAF, Pilot and Major Noel F. Widdifield, USAF, Reconnaissance Systems Officer, set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over A Known Course when they flew a Lockheed SR-71A-LO, serial number 61-7972, from New York to London in 1 hour, 54 minutes, 56.4 seconds. They averaged 2,908.026 kilometers per hour (1,806.964 miles per hour).
This same SR-71 set numerous speed and altitude records during its career. It is in the collection of the Smithsonian Institution National Air and Space Museum.
Lieutenant Colonel William Atkinson Jones III, United States Air Force.
1 September 1968: Two U.S. Air Force McDonnell F-4D Phantom II fighters were on a pre-dawn strike against the Ho Chi Minh Trail, near the Ban Karai Pass. Both Phantoms, call signs CARTER 01 and CARTER 02, were hit by anti-aircraft gunfire and their crews had to eject. Both pilots from CARTER 01 were quickly picked up, but the aircraft commander of CARTER 02 was hidden by the jungle. The Weapons System Officer was never seen again.
A Combat Search and Rescue (CSAR) mission was immediately sent out to locate and rescue the missing airmen. Two Sikorsky HH-3 Jolly Green Giant helicopters, the recovery team, were escorted by four Douglas A-1 Skyraiders to help in the search and to suppress any enemy gunfire that was trying to shoot down the rescue helicopters.
The Skyraider was a Korean War era carrier-based attack airplane originally in service with the U.S. Navy. It had been replaced by modern jet aircraft, but the Air Force found that its slow flight and ability to carry a heavy fuel and weapons load were ideal for the CSAR escort mission.
The four Skyraiders were from the 602nd Special Operations Squadron at Nakhom Phanom, Thailand. They operated with the call sign SANDY. Lieutenant Colonel William A. Jones III, the squadron commanding officer, on his 98th combat mission, was the on-scene commander flying SANDY 01, an A-1H, serial number 52-139738.

MEDAL OF HONOR JONES, WILLIAM A., III
Rank and organization: Colonel, U.S. Air Force, 602d Special Operations Squadron, Nakon Phanom Royal Thai Air Force Base, Thailand
Place and date: Near Dong Hoi, North Vietnam, 1 September 1968
Entered service at: Charlottesville, Virginia
Born: 31 May 1922, Norfolk, Virginia
Citation: For conspicuous gallantry and intrepidity in action at the risk of his life above and beyond the call of duty. Col Jones distinguished himself as the pilot of an A-1H Skyraider aircraft near Dong Hoi, North Vietnam. On that day, as the on-scene commander in the attempted rescue of a downed U.S. pilot, Col. Jones aircraft was repeatedly hit by heavy and accurate antiaircraft fire. On 1 of his low passes, Col. Jones felt an explosion beneath his aircraft and his cockpit rapidly filled with smoke. With complete disregard of the possibility that his aircraft might still be burning, he unhesitatingly continued his search for the downed pilot. On this pass, he sighted the survivor and a multiple-barrel gun position firing at him from near the top of a karst formation. He could not attack the gun position on that pass for fear he would endanger the downed pilot. Leaving himself exposed to the gun position, Col. Jones attacked the position with cannon and rocket fire on 2 successive passes. On his second pass, the aircraft was hit with multiple rounds of automatic weapons fire. One round impacted the Yankee Extraction System rocket mounted directly behind the headrest, igniting the rocket. His aircraft was observed to burst into flames in the center fuselage section, with flame engulfing the cockpit area. He pulled the extraction handle, jettisoning the canopy. The influx of fresh air made the fire burn with greater intensity for a few moments, but since the rocket motor had already burned, the extraction system did not pull Col. Jones from the aircraft. Despite searing pains from severe burns sustained on his arms, hand, neck, shoulders, and face, Col. Jones pulled his aircraft into a climb and attempted to transmit the location of the downed pilot and the enemy gun position to the other aircraft in the area. His calls were blocked by other aircraft transmissions repeatedly directing him to bail out and within seconds his transmitters were disabled and he could receive only on 1 channel. Completely disregarding his injuries, he elected to fly his crippled aircraft back to his base and pass on essential information for the rescue rather than bail out. Col. Jones successfully landed his heavily damaged aircraft and passed the information to a debriefing officer while on the operating table. As a result of his heroic actions and complete disregard for his personal safety, the downed pilot was rescued later in the day. Col. Jones’ profound concern for his fellow man at the risk of his life, above and beyond the call of duty, are in keeping with the highest traditions of the U.S. Air Force and reflect great credit upon himself and the Armed Forces of this country.

The United States Navy and Marine Corps adopted the Douglas Aircraft Company AD-1 Skyraider just after the end of World War II. The U.S. Air Force recognized its value as a close air support attack bomber, but it wasn’t until the early months of U.S. involvement in the Vietnam War that a number of Skyraiders were transferred to the U.S.A.F.
This is the Douglas A-1H Skyraider flown by LCOL Jones, 1 September 1968. Though it was extensively damaged by anti-aircraft gunfire and the subsequent fire, 52-139738 was repaired and returned to service. On 22 September 1972, -738 was shot down over Laos. It was the last Skyraider shot down during the Vietnam War.
These aircraft were identified by Department of the Navy, Bureau of Aeronautics serial numbers, commonly referred to as “bureau numbers,” or “bu. no.” Once acquired by the Air Force, the two-digit fiscal year number in which the airplane was contracted was added to the bureau number, resulting in a serial number with a format similar to a standard U.S.A.F. serial number. For example, Lieutenant Colonel Jones’ Skyraider, A-1H 52-139738, was originally U.S. Navy AD-6 Skyraider Bu. No. 139738, authorized in 1952. (The Douglas AD series was redesignated A-1 in 1962.)
Douglas A-1H Skyraider 52-137593 (U.S. Air Force)
The Douglas AD-6 (A-1H) Skyraider was a single-place, single-engine attack aircraft. A low-wing monoplane with conventional landing gear, it had folding wings for storage aboard aircraft carriers. The A-1H Skyraider was 39 feet, 3 inches (11.963 meters) long with a wingspan of 50 feet, ¼ inch (15.246 meters) and overall height of 15 feet, 8 inches (4.775 meters). The total wing area was 400 square feet (37.16 square meters). Its had an empty weight of 12,072 pounds (5,476 kilograms) and its maximum takeoff weight was 25,000 pounds (11,340 kilograms).
The A-1H was powered by an air-cooled, supercharged, direct-fuel-injected, 3,347.66-cubic-inch-displacement (54.858 liter) Wright Aeronautical Division R-3350-26WA Duplex-Cyclone (Cyclone 18 836C18CA1) engine. This was a twin-row 18-cylinder radial, with a compression ratio of 6.7:1 and water/alcohol injection. This engine had a normal power rating at Sea Level of 2,300 horsepower at 2,600 r.p.m., and 2,700 horsepower at 2,900 r.p.m. to for take off. 115/145-octane aviation gasoline was required. The engine drove a four-bladed Aeroproducts constant-speed propeller 13 foot, 6 inch (4.115 meters) diameter, through a 0.4375:1 gear reduction. The R-3350-26WA was 4 feet, 7.62 inches (1.413 meters) in diameter and 6 feet, 6.81 inches (2.002 meters) long. It weighs 2,848 pounds (1,292 kilograms), dry.
The A-1H Skyraider had a cruise speed of 164 knots (189 miles per hour/304 kilometers per hour) and a maximum speed of 297 knots (342 miles per hour/550 kilometers per hour) at 15,400 feet (4,694 meters). The A-1H could climb to 20,000 feet (6,096 meters) in 9.5 minutes. The ceiling was 31,900 feet (9,723 meters). Carrying a 2,000 pound (907 kilogram) bomb load, its combat radius was 260 nautical miles (299 statute miles/482 kilometers).
The A-1H was armed with four 20 mm M3 autocannon with 200 rounds of ammunition per gun. The Skyraider could carry a combination of external fuel tanks, gun pods, bombs or rockets on 15 hardpoints.
