Douglas Flying Club Glider / Flyer / Bomber
In 1908 there was a group of eight to nine different people in town known as the Douglas flying club, Arizona … and these people built what was known as the Douglas Glider.
The members of the Douglas flying club were A.M. Williams, John C. Wright, Judge Forte, Ben Goodsell, Felipe Mazon, Ted Bowden, Charles M. Ford and Sparks Y. Faucet.
The glider was built in downtown Douglas and flown off of 15th Street between A and Washington Ave. It’s made most of rattan and bamboo, and metal fittings and fabric that covers over the wings.
Initially, to get the glider off the ground, horses would be attached a hitch on the front of the glider that was then attached to harnesses. The horses would then start running and as the glider began to lift off the ground the hitch would come free from the harnesses. It didn’t fly very far but it did get off the ground.
They had people there watching them do this and after they were done they would pass the hat and people would contribute a little money to it and if they had enough money they would make another run.
That evolved into an airplane when they hung a motor on it and put a propeller on the motor and then put wheels on the glider making it an airplane.
Following 1908 modifications were made to the Douglas Glider, Schultz said. It would later change its name to the Douglas Flyer then The Douglas Bomber and be used in the Border War from 1910-20.

Douglas F5D Skylancer
The Douglas F5D was envisaged originally as an improved all-weather development of the F4D (F-6) Skyray, and two prototypes were ordered in 1953 under the designation F4D-2N.
Substantial changes, including wings of much reduced thickness/chord ratio, a lengthened fuselage, revised vertical tail surfaces and the introduction of a new cockpit canopy brought the redesignation F5D-1 (subsequently named Skylancer) before the first flight was recorded on 21 April 1956.
The F5D Skylancer was basically an enlarged version of the Skyray with a fuselage of increased fineness ratio and a wing of reduced thickness/chord ratio for higher supersonic performance on the power provided by a Pratt & Whitney J57-P-8 afterburning turbojet.
The first of four XF5D prototypes went supersonic on its initial flight, and by then, nine preproduction and 51 production examples had been ordered, but following early flight testing the programme was cancelled except for two of the preproduction aircraft. The performance of the F5D was little better than that of the Chance Vought F8U-1 which was on the point of entering service.
By 1957 two prototypes of the XF5D-1 Skylancer were flying.
The four F5D-1s were used by the US Navy as flying testbeds for a variety of equipment before they were handed over to NASA for experimental use.
Two prototypes given to NASA in late 1960 essentially as castaways. Neil Armstrong flew one of the F5Ds on 26 September 1960 during a visit to NASA Ames and realised the F5D could serve well in a study of Dyna-Soar abort procedures because its wing planform was a match for the X-20.
Armstrong began flight tests in the F5D in July 1961, and after no fewer than 10 flights, developed an effective maneuver of X-20 abort. His last flight in the F5D was 1 November 1961.
Neil Armstrong’s last flight as a Flight Research Centre employee occurred on Friday 28 September 1962. It was another low L/D flight in an F5D.

Douglas F6 / F4D-1 Skyray
US Navy interest in German delta-wing research led, in 1947, to the design by Douglas of a carrier-based interceptor with a variation of the pure delta wing. Approval of the Douglas design was signified by the award of a contract for two Douglas XF4D-1 prototypes on 16 December 1948, the first making its maiden flight on 23 January 1951 powered by a 2268kg thrust Allison J35-A-17 engine. This represented an emergency powerplant, resulting from delays in development of the Westinghouse J40 turbojet which had been the planned engine. Both prototypes were flown subsequently with the XJ40-WE-6 developing 3175kg thrust and the XJ40-WE-8 which had a rating of 5262kg with afterburning, but problems with this engine programme led to final selection of the Pratt & Whitney J57 engine for production aircraft.
Douglas F6 / F4D-1 Skyray Article
The F4D Skyray was a cantilever mid-wing monoplane, the wing of modified delta configuration incorporating elevons to serve collectively as elevators or differentially as ailerons. The tail unit had only swept vertical surfaces, landing gear was of retractable tricycle-type. The pilot was accommodated well forward of the wing.
The potential of the F4D was demonstrated effectively by the second prototype on 3 October 1953, then powered by the XJ40-WE-8 turbojet, which set a new world speed record of 1211.746km/h.
The first production F4D-1 was flown on 5 June 1954, powered by a Pratt & Whitney J57-P-2 turbojet developing 6123kg thrust with afterburning, but it was not until 16 April 1956 that deliveries began, initially to US Navy Squadron VC-3. The 419th and last production aircraft was delivered on 22 December 1958, but in the intervening period a change had been made by installation of the higher-rated J57-P-8 engine. All aircraft retained the F4D-1 designation, the popular (derived) name being Ford.
The new Douglas factory at Torrance (Plant B-6) in May 1954 was in volume production with both the AD-5 and 6 Skyraider and the F4D-1 Skyray, the latter with the J57 turbojet with afterburner. This leaves the El Segundo division almost clear to turn out twin-jet Skywarriors. Navy contracts for the Skyray were sufficient to keep Torrance busy until the end of 1956. Reports came to the effect that a new variant, the F4D-2, was being developed “with some configuration changes.” After manufacture at Torrance, Skyrays are put aboard a flat truck and taken to El Segundo, where final operational equipment is installed preparatory to flight testing.
At the peak of its utilisation, the Skyray equipped 11 US Navy, six US Marine and three reserve squadrons, but none was used operationally. The type survived in first-line service until the late 1960s, with two front-line squadrons not converting to the type until 1964. It was redesignated F-6A in September 1962.

Douglas F10 / F3D Skyknight
Unique in being the US Navy’s first jet-powered night-fighter, the Skyknight began development in 1945, Douglas being awarded a contract for three XF3D-1 prototypes in April 1946.
The type emerged as a cantilever mid-wing monoplane of all-metal construction, the wings incorporating hydraulic folding for carrier stowage. The circular-section fuselage mounted hydraulically actuated speed-brakes, provided side-by-side pressurised accommodation for the pilot and radar operator, and carried at the rear a tail unit very similar to that of the D-558-1 Skystreak. An unusual feature was a crew escape tunnel, extending from the rear of the cabin to the underside of the fuselage. Landing gear was retractable tricycle-type, and the powerplant of the prototypes was two 1361kg thrust Westinghouse J34-WE-24 turbojets, mounted on the lower edges of the forward fuselage, beneath the wing roots.
The first prototype made its maiden flight from Muroc (now Edwards AFB) on 23 March 1948, this event being followed in June by an order for 28 production F3D-1 (later redesignated F-10A) fighters while company testing was still in progress. The first of these was flown on 13 February 1950. Service acceptance trials were conducted by VC-3 at Moffett Field from December 1950, the type then being handed over to Marine Night Fighter Squadron VMF(N)-542. The F3D-1 differed from the prototypes by having improved avionics and equipment and, as delivered initially, had 1361kg thrust J34-WE-32 turbojets. These engines were uprated subsequently to 1474kg thrust, becoming redesignated J34-WE-34. In the event, the F3D-l did not see action.
Before delivery of the first F3D-1, Douglas had received a contract for production of an improved F3D-2 (F-l0B), which was to be the major and ultimate production version, with a total of 237 built in the early 1950s. It was intended that the F3D-2 should be powered by 2087kg thrust J46-WE-3 turbojets, but development of this engine was abandoned and, instead, they were all powered by J34-WE-36s. Improvements included the provision of an autopilot and updated systems and equipment. The first of these F3D-2s was flown on 14 February 1951 and all had been delivered just over a year later. It was this model which made the Skyknight’s combat debut with VMF(N)-513 in June 1952.
The Skynight saw extensive use in Korea, this all-weather fighter accounting for the majority of all victories scored by the US Navy and US Marine Corps. On the night of 2 November 1952, it succeeded in downing a North Korean Yakovlev Yak- 15, this marking the first recorded kill in a jet-versus-jet combat at night. Even more remarkable is the fact that the F3D ended the Korean War as the most successful naval fighter type in terms of aircraft destroyed in air combat.
In US Navy service, the F3D enjoyed only a brief front-line career, being quickly relegated to radar intercept training duties as the F3D-2T and F3D-2T2 (TF-10B), the last example being retired in the early 1960s. US Marine Corps composite squadrons continued to use the F3D-2Q (EF-10B) type in ECM duties, however, and the type again saw action in Vietnam with VMCJ-1 until 1969 when it was finally replaced by the Grumman EA-6A Intruder.
Two examples of the Skyknight were used by the US Army in support of air defence missile testing at White Sands, New Mexico.
A proposed swept-wing version known as the F3D-3 was cancelled in 1952, but other service variants were the missile-armed F3D-1M and F3D-2M (MF-l0B).

Douglas SBD Dauntless / A-24
The SBD entered production in 1940.
Crewed by a pilot and an observer/gunner the SBD-3, which appeared in March 1941, was powered by a l000hp R-1820-52. In contrast to the earlier models, the SBD-3 had 0.50 armour in the cowling, self-sealing tanks, and protective armour, 584 had been built by December 1941. Seven hundred and eighty SBD-4 models were built at El Segundo, California while 2,409 of the SBD-5s were built at the Douglas plant at Tulsa, Oklahoma.

Douglas DC-10 / KC-10
Douglas designed the DC-10 in 1966, competing directly with Lockheed to produce an airbus capable of operating from normal-length runways. By designing the DC-10 around three General Electric CF6-6 turbofan engines, Douglas avoided the financial difficulties encountered by Lockheed with the Rolls-Royce RB.211. In a multi-company manufacturing agreement, Convair produces the fuselage and Aeritalia the fins (vertical stabilizers). The -10 is a short/medium-haul version; the long-range -30 and -40 have an extra forward-retracting main gear, uniquely mounted on the centreline. An aircraft with a fixed wing sweep (the DC-10 wing, designed just before the advanced supercritical form was introduced, is broad and strongly swept) cannot be best for all ranges, but the DC-10’s sales record of 250 testifies to its attraction as a sophisticated wide¬bodied jet that can fly global routes.
The Series 10, able to accommodate up to 380 economy class passengers on domestic routes, was first flown on 29 August 1970, certified on 29 July 1971, and made its first scheduled passenger flight with American Airlines on 5 August 1971. Introduction of DC-10 service-between Los Angeles and Chicago came one week after American formally accepted the trijet from McDonnell Douglas. It was followed by the inter-continental range Series 20, which flew for the first time on 28 February 1972.
Conversion of the CF6-50A engines to -50C standard increases the thrust from 49,000 lbs to 51,000 lbs.
Turkish airlines took delivery of three DC-10-10 between December 1972 and February 1973; TC-JAU, TC-JAV, and TC-JAY. TC-JAV was lost at Paris in 1974.
First flight of the long range Pratt & Whitney JT9D powered McDonnell Douglas DC 10 20 took place on February 28, 1972. Northwest Airlines having ordered 14, with 14 more on option
A derivative of the commercial DC-10-30CF, selected in 1977 as the USAF’s advanced tanker/cargo aircraft (ATCA), the first KC-10A flew in July 1980. The aircraft has high-flow-rate, 5,680lit/min refuelling boom plus an independent, 2,2701it/min hose-drogue system. As a transport the KC-10 has a cargo capacity comparable with that of the C-5 to 8,300km range, but is superior over longer ranges up to 18,500km.
Some 445 DC 10s were delivered since the first went into service in 1971, the last in July 1989 to Nigerian Airways.

Douglas DC-9 / C-9 Nightingale
McDonnell Douglas’s only four engined civil jet airliner, the DC 8, preceded the company’s very successful DC 9 twin jet, which first flew at Long Beach, California, on February 25, 1965.
By 1962 Douglas’s Model 2086 had become a firm design, and the subject of negotiations with several opera¬tors. At last Delta agreed to buy a fleet and the Model 2086 became the DC-9 on 8 April 1963. In April 1963 the company announced that it would build the DC 9 and John Brizendine, who ten years later became President of Douglas Aircraft, was named programme manager. The programme was given top priority with more than 40,000 man hours a week expended on the project. The primary aims of the project were to produce a simple and reliable, easy to operate and maintain airliner. Construction of the prototype began in July 1963 and the first DC-9 flew from Long Beach on 25 February 1965. US airlines made no advance orders. Douglas’ own capital was tied up in modifications to the DC-8, so the company reduced the risk by utilizing the DC-8’s flight deck, and persuading major suppliers to design and manufacture different parts, receiving payment only as each aircraft was delivered to a customer. De Havilland Canada produced the complete wing, rear fuselage and tail. Later, the Douglas Aircraft Company bought part of their Toronto factory, and continued production there. By producing a series of stretched versions, to stay abreast of the demand for larger capacity aircraft, Douglas outsold all competitors in the same category.
A big manufacturing programme was launched, with DH Canada making the wings, rear fuselage and tail. From the start Douglas planned to offer different versions, and the original DC-9 Series 10 could weigh anything from the basic 77,000lb with JT8D-5 engines of 12,000-lb thrust to 90,000 lb with extra fuel and 14,000-lb JT8D-1 or -7 engines. The first off the line flew a month early, on 25 February 1965, and services began with Delta on 8 December the same year. A total of 137 were built.
Douglas offered a stretched ‘DC-9B’ and on 25 February 1965 and won an Eastern order. The designation was changed to DC-9 Series 30, with 14,500-lb engines and a considerable stretch both to the span and length. The weight was 98,000 lb, matched by full-span slats and double-slotted flaps. The first Srs 30 flew on 1 August 1966. Subsequently the Srs 30 (503 sold) grew to 108,000 lb with more-powerful engines, seating up to 115.
Then came the Srs 20, for operation out of difficult airports by SAS. It combined the wings and engines of the Srs 30 with the original short fuselage. On 28 November 1967 Douglas, by now part of McDonnell Douglas, flew the DC-9 Srs 40, with engines of up to 16,000-lb thrust, enabling weight to rise to 122,000lb. The fuselage was stretched yet again, to seat up to 132. To meet airline demand for a DC 9 with larger capacity the 40 was developed with a longer fuselage enclosing a 132 seat configuration. Below floor cargo space was also increased. This version entered service in March 1968.
Last of the original DC-9 variants was the Srs 50, first flown on 17 December 1974. This introduced many attractive new features, but the main difference was that, still keeping at 122,000-lb weight, the body was stretched yet again to seat 139. The 50 began airline operation in August 1975.
Each DC 9 was, in practice, a stretched version of the Series 10. The 20 carried 115 passengers and featured a longer wingspan and a high lift wing system of leading edge slats for short field performance. The 30 was the most widely used. US Air Force versions were designated C 9A Nightingale and VC-9C and C 9B Skytrain for the US Navy.
Douglas also offered various cargo and convertible versions. A total of 649 DC-9s had been delivered by 1 February 1972. This includes the C-9A variant for the 375th Aeromedical Wing of the USAF MAC. Important orders were also placed by the US Air Force and Navy (Marines) for the C-9A Nightingale aeromedical aircraft, the C-9B Skytrain II (longest-ranged of all versions) and VC-9C for VIP missions. Each of the C-9A can carry 30-40 litter patients, two nurses and three aeromedical technicians, and have intensive care compartments. Ten were converted. The final aircraft off the assembly line, a DC¬9 30, was transferred to the US Navy as a C 9B in October 1982.
Thrust for the 976 DC 9s completed over an 18 year production run was provided exclusively by the Pratt & Whitney JT8D family of engines. In mid 1998 there were in excess of 870 of the type being flown by over 70 operators worldwide.
A new version was launched as the DC-9 Super 80, with an order from Swissair, closely fol¬lowed by Austrian and Southern, in October 1977. The first aircraft flew on 18 October 1979. Changes included a further (and very large) stretch to the fuselage, an extension to the span at both the wing roots and tips, a digital electronic flight guidance system, a further increase in fuel capacity and, not least, fitting the JT8D-200 series engine. The refanned engine, used initially in -209 form at 18,500-lb thrust, dramatically reduced noise and eliminated worries over impending noise legislation. Seating capacity was typically up to 172.
In 1983 the company at last abandoned the famed ‘DC’ and adopted ‘MD’ for its designations, McDonnell Douglas launched the MD-80.
Altogether Douglas sold 976 DC-9s, production being completed in September 1982.

Douglas DC-8
The Douglas Aircraft Company announced its intention, on 7 June 1955, to enter the pure jet stakes with the DC-8. Originally powered by the same Pratt & Whitney JT3 turbofans as the 707, it had a fractionally more slender body, less wing sweep, and fully powered flight controls. To reduce drag and avoid stress between wing and fuselage, the aerofoil changes shape toward the root, becoming flatter on top and more curved beneath. Douglas began assembling the first DC-8 in February 1957 and, there being no prototype as such, was rolled out and first flew on 30 May 1958.
There are four main families of DC-8s: Douglas made the first five versions the same size differing only in power and fuel capacity. Douglas had announced that all projected versions would have the same overall dimensions. It adhered to this policy until 1965, and the first five versions of the DC-8 have an identical airframe, with uniform electrical, hydraulic, control and air conditioning systems. The intercontinental versions differ from the domestic models only in having extra fuel capacity and the structural modifications needed to carry the additional fuel. The modifications are limited to the use of thicker skin and stronger material within the wing structure, the aft portion of the fuselage and the tailplane. The landing gear is also more robust in the case of the heavier intercontinental versions.
It was offered in several models, the series 10 for domestic services, the series 30 for longer ranges and the Series 40 powered by the Rolls Royce Conway bypass engine for Trans Canadian Airlines, Air Canada.
On 23 July 1959 the first DC-8 with Rolls-Royce Conway engines made its first flight from Long Beach, California. It was the ninth DC-8 to fly in 14 months.
A DC-8-40 became the first jet airliner to exceed the speed of sound when, in 1961, it reached Mach 1.012 (667 mph) in a shallow dive. In 1959 Douglas introduced an extended wing leading edge and slightly extended tips, allowing weight to reach 310,000 lb.
The DC-8 with JT-3C engines received its FAA Type Approval on 31 August 1959 and went into service with United Airlines and Delta Airlines on 18 September 1959.
In 1960 the Series 50 introduced the JT3D turbofan engine, with weights up to 325,000lb. The Series 50 evolved after Pratt and Whitney developed the new JT3D turbofan housed in new nacelles with distinct exhaust louvres on either side. The 50 range was developed into the 51 for domestic operations, the 52, 53 and 55 for long range versions differing in the model of engine fitted. A subsequent version, the 54, was developed as a freighter.
The Series 50 DC 8 had a still air range of around 6900 miles with a maximum cruise of 580 miles an hour at 220,000 lb. The series 52 had a total fuel capacity of 150,055 lb. The forward freight compartment had a capacity of 690 cu ft and the rear a usable capacity of 700 cu ft.
In April 1965 Douglas announced the Super Sixty series. This comprised the DC-8-61, stretched by 36ft 8in to seat up to 259 pas¬sengers; the -62 with only a small stretch, to seat 189, but with extra fuel for very long range, enhanced by an improved wing and engine pods; the -63, fuselage lengthened by 36.7 ft. (11.18 m.), an extended wing span. Powered by JT3Ds of up to 19,000-lb thrust, these extended the DC-8 line from 293 to 556, production continuing until 1972. The Super Sixties proved such good aircraft that in the early 1980s 110 were retrofitted with the CFM56-2 engine as the DC-8-71.
A total of 556 DC-8s were produced before the production line closed in early 1972.
The French Air Force operated an electronic reconnaissance version of the DC-8. They were equipped with large antenna pods on both wingtips and under the fuselage. Reconnaissance squadron Escadron Electronique 51 ‘Aubrac’ operated at least two converted DC-8, 45570 and 46043, from 1977 from Evreux airfield. The first ELINT DC-8 was ordered as early as 1973.
