23 September 1917

Leutnant Werner Voss

23 September 1917: Leutnant Werner Voss, commanding officer of Jagdstaffel 10 of the Deutsche Luftstreitkräfte (German Air Force), a leading fighter ace with 48 confirmed victories, was shot down during a battle which lasted at least eight minutes and involved seven British pilots, themselves aces.

Though Voss’ machine gun fire damaged most of his opponents’ airplanes, his own was hit by fire from at least two of the British airplanes. Voss was struck by three bullets.

His airplane, a prototype Fokker F.I triplane, serial number 103/17, went into a steep dive and crashed north of Frezenberg, Belgium. Voss was killed.

Major James Thomas Byford McCudden, VC, DSO and Bar, MC and Bar, MM, one of the British pilots involved in the dogfight, later said of Voss,

“As long as I live I shall never forget my admiration for that German pilot, who single-handed fought seven of us for ten minutes and also put some bullets through all our machines. His flying was wonderful, his courage magnificent, and in my opinion he was the bravest German airman whom it has been my privilege to see fight.”

The Fokker F.I was a prototype single-engine, single-seat triplane fighter, designed and built by Fokker Flugzeugwerke GmbH, Schwerin, Germany. After very slight changes, the production version would be designated Fokker Dr.I. The fuselage was constructed of steel tubing and covered with fabric. The wings used plywood ribs and a boxed plywood spar.

The F.I was 5.770 meters (18 feet, 11.2 inches) long. The upper wing had a span of 7.190 meters (23 feet, 7.1 inches); the middle wing, 6.225 meters (20 feet, 5 inches); and the lower wing, 5.725 meters (18 feet, 9.4 inches). All three wings had a chord of 1.000 meters (3 feet, 3.4 inches). The airplane had an overall height of 2.950 meters (9 feet, 8.1 inches). Its empty weight was 405 kilograms (893 pounds), and the gross weight was 587 kilograms (1,294 pounds).

Originally built with a Motorentfabrik Oberursel Ur.II nine-cylinder rotary engine rated at 110 horsepower (a license-built copy of the French Le Rhône 9J engine), Werner Voss had an actual Le Rhône 9J, serial number J6247, installed to replace the Ur.II.

The Le Rhône 9J, produced by Société des Moteurs Le Rhône, was an air-cooled, normally aspirated, 15.074 liter (919.85 cubic inches) nine-cylinder rotary engine, capable of producing 113 horsepower at 1,200 r.p.m., and a maximum 135 horsepower at 1,350 r.p.m. As the engine rotated, it turned a two-bladed Axial Proppellerwerk AG fixed-pitch, laminated wood propeller with a diameter of 2.660 meters (8 feet, 8.7 inches). The Le Rhône 9J was 850 millimeters (2 feet, 9.47 inches) long and 970 millimeters (3 feet, 2.19 inches) in diameter. It weighed 137 kilograms (302 pounds).

The Fokker F.I had a maximum speed of 185 kilometers per hour (115 miles per hour) at Sea Level and 166 kilometers per hour (103 miles per hour) at 4,000 meters (13,123 feet ). The service ceiling was 7,000 meters (22,966 feet). It carried fuel for approximately 1½ hours of flight.

The F.I was armed with two fixed 8mm Spandau LMG 08/15 machine guns, synchronized to fire forward through the propeller arc. The fighter carried 550 rounds of ammunition per gun.

Werner Voss’ triplane, 103/17 (Wn. 1730), was a prototype, Versuch 5, or V5, ordered on 14 July 1917 and accepted by the German Air Force on 16 August. It was sent to Jagdstafell 10 on 21 August.

A British intelligence officer who examined the wreckage of Voss’ Fokker F.I described it as having camouflaged green upper surfaces and blue lower surfaces. Photographs of 103/17 show painted eyes and a mustache on the engine cowling, which are believed to have been inspired by Japanese kites that Voss had flown as a child.

Leutnant Werner Voss had been awarded the famous Pour le Mérite (the “Blue Max”), Germany’s highest award; the Hausorden von Hohenzollern (the Cross of the Order of the Royal House Order of Hohenzollern with Crown and Swords); and the Eisernes Kreuz (Iron Cross), 1st and 2nd Class.

23 September 1913: Pioneering aviator Eugène Adrien Roland Georges Garros (6 October 1888–5 October 1918) was the first pilot to fly across the Mediterranean Sea. At 5:47 a.m., he departed Fréjus, Côte d’Azur, France, in a Morane-Saulnier G and flew to Bizerte, Tunisia, 470 miles (756 kilometers) to the south. He arrived at 1:40 p.m., having been airborene 7 hours, 53 minutes.

Reportedly, the airplane carried sufficient fuel for just 8 hours of flight. According to a contemporary report, only 5 liters (1.32 U.S. gallons) of fuel remained when he landed.

Garros flew on to Kassar Said Aerodrome the following day. His airplane was then dismantled and shipped back to France.

On 15 October 1913, Roland Garros was appointed Chevalier de la légion d’honneur.

The Aéroplanes Morane-Saulnier Type G was a two-place, single-engine monoplane, which had first flown in 1912. The airplane used wing-warping for roll control. It’s landing gear consisted of two wheels and a tail skid. The wooden framework was primarily ash and was covered in fabric. It was 21 feet, 6 inches (6.553 meters) long with a wingspan of 30 feet, 6 inches (9.296 meters). The wing had a chord of 6 feet, 0 inches (1.829 meters), no dihedral, and the wingtips were swept. The airplane had an empty weight of 680 pounds ( 308 kilograms) and a maximum weight of 1,166 pounds (529 kilograms).

The pilot’s instrument panel had a revolution indicator (tachometer), a barograph, and a compass.

The Morane-Saulnier G was powered by an air-cooled 11.835 liter (722.22 cubic inches) Société des Moteurs Gnome Lamda seven-cylinder rotary engine with a single Bosch magneto, with a nominal rating of 80 horsepower (one source indicates that the engine actually produced 67.5 horsepower at 1,250 r.p.m.), and driving a Chauvière Hélice Intégrale laminated walnut fixed-pitch propeller with a diameter of 7 feet, 10 inches (2.570meters).

The airplane had a 14 gallon¹ (63.65 liters) main fuel tank near the engine, and a second 8 gallon (36.37 liters) tank in the cockpit. Fuel had to be transferred forward by using a hand-operated pump. A 5 gallon (22.73 liters) tank for lubricating oil was adjacent to the main fuel tank.

Garros’ airplane maintained an average speed of 59.5 miles per hour (96 kilometers per hour) for this flight. The Morane-Salnier G had a maximum speed of 76 miles per hour (122 kilometers per hour).

The Morane-Saulnier G was produced under license by Grahame-White Aviation Company, Hendon Aerodrome, London, England, and by Dux at Moscow, Russia. More than 150 Type Gs were built.

Roland Garros was born 6 October 1988 at Saint-Denis, Réunion (an island in the Indian Ocean). He was a racer and test pilot who had set many aviation records, including a Fédération Aéronautique Internationale World Altitude Record of 5,610 meters (18,406 feet), set 11 September 1912. (FAI Record File Number 15888)

Garros flew in World War I as a fighter pilot for France and shot down a total four enemy airplanes. Garros’ airplane went down behind enemy lines and he was captured, 18 April 1915. He escaped nearly three years later and returned to France. For his military service, he was promoted to Officier de la Légion d’honneur, 6 March 1917. He was also awarded the Croix de Guerre.

Lieutenant d’infantrie Eugène Adrien Roland Georges Garros, Officier de la Légion d’honneur, Aéronautique Militaire, flying a SPAD S.XIII C.1, Nº. 15403, was shot down by the German ace, Leutnant Hermann Habich, near Vouziers, France, and killed, 5 October 1918, one day before his 30th birthday.

22 September 1966

22 September 1966: Ansett-ANA Flight 149, a Vickers Viscount Type 832 medium-range airliner, registration VH-RMI, departed Mount Isa Airport (ISA) at 12:08 p.m., enroute to Longreach Airport (LRE), both located in Queensland, Australia. Captain John Kenneth Cooper was in command, with First Officer John Gillam. The two flight attendants (“air hostesses”) were Beverly Heeschen, aged 24, and Narell Davis, 19. There were twenty passengers aboard.

At 12:52 p.m., Flight 149 reported, “Longreach this is Romeo Mike India on emergency descent.” Two minutes later it reported that there were fire warnings for both the Number 1 and Number 2 engines. Captain Cooper radioed, “I have an engine on fire. The other is stopped and I can’t feather it. Request permission to divert to Winton.” [Winton Airport, WIN]

While descending between 4,000 and 3,500 feet (1,200 and 1,067 meters) above ground level (AGL) at 170 knots, the airliner’s left wing failed between the Number 1 and Number 2 engines. The wing folded up and over, striking the top of fuselage which was cut open by the propeller of the Number 1 engine. The mid-cabin structure above the floor was torn away and the rear of the fuselage broke off. Air Hostesses Davis and Heeschen, along with several passengers, were pulled out of the cabin by the slipstream.

The remainder of the airplane—the forward fuselage, lower mid fuselage, right wing with engines 3 and 4, impacted the ground 11 miles (17.7 kilometers) west southwest of Winton, Queensland. The wreck was engulfed in flames. All those aboard were killed.

The accident investigation determined that the probable cause of the crash was:

The means of securing the oil metering unit to the no.2 cabin blower became ineffective and this led to the initiation of a fire within the blower, which propagated to the wing fuel tank and substantially reduced the strength of the main spar upper boom. It is probable that the separation of the oil metering unit arose from an out-of-balance condition induced by rotor break-up but the source of the rotor break-up could not be determined.

Captain Cooper had flown Consolidated PBY Catalina flying boats with the Royal Australian Air Force during World War II. He joined Ansett-ANA in 1951. At the time of the accident, he had a total of approximately 14,300 flight hours. Captain Roland E. Black, who had conducted Cooper’s last airline proficiency check, described him as a “well above average pilot.”

The Vickers Viscount was a four-engine turboprop-powered civil transport which first flew in 1948. It was in production from 1948 to 1963 with 445 airplanes built. VH-RMI was a  Vickers Viscount Type 832, one of three built for Ansett-ANA in 1959 by Vickers-Armstrongs, Ltd., at Bournemouth-Hurn Airport, Dorset, England. It was operated by a flight crew of 2 and had 56 passenger seats, of which 4 were in a rear lounge.

The airliner was 85 feet, 6 inches (26.060 meters) long with a wingspan of 93 feet, 8 inches (29.464 meters) and overall height of 26 feet, 9 inches (8.153 meters). Empty weight of the similar Type 810 was 41,276 pounds (18,723 kilograms) and its maximum takeoff weight was 67,500 pounds (30,618 kilograms).

The Type 832 Viscount was powered by four Rolls-Royce RB.53 Dart Mk.525 (RDa.7/1) turboprop engines. The Dart was an axial-flow engine with a 2-stage centrifugal compressor, 7 combustion chambers and a 3-stage turbine. The Mk.525 was rated at  1,910 shaft horsepower at 15,000 r.p.m., with 470 pounds of residual thrust (2.09 kilonewtons). It was derated to 1,800 s.h.p. for takeoff. The Dart Mk.525 is 8 feet, 1.6 inches (2.479 meters) long, 3 feet, 1.9 inches (0.963 meters) in diameter and weighed 1,207 pounds (547.5 kilograms). The turboprop engines drove four-bladed Rotol constant-speed propellers which had a diameter of 10 feet (3.048 meters).

The Viscount had a maximum speed of 352 miles per hour (567 kilometers per hour), range of 1,380 miles (2,221 kilometers) and service ceiling of 25,000 feet (7,620 meters).

In the seven years since its first flight, 8 April 1959, VH-RMI had accumulated 18,634 total flight hours.
