Delta Air Lines History and TriStar Fleet


Delta, the oldest passenger airline available, followed its roots back to 1925 and, in the first form, operated the crop dusting services with Petrel 31 as Huff Daland Dusters. He named it the first specially designed agricultural plane, the Hedgehog. Protect cocoon beetles from cotton fields in the south of the United States.

Three years later, independence and the Delta Air Service placed the fledgling concern on the brink of gradual growth.

A low, four-route route network enabled Dallas, Shreveport, Monroe and Jackson to serve from June 17, 1929.

Ten years later, Lockheed bought the L-10A Electra and Douglas DC-3 cabin airplanes from Savannah, Knoxville and Cincinnati, and from Chicago to Miami in 1946 through these cities. received an award though. An additional goal in Charleston.

Larger, faster and more advanced four-engine piston liners improved the image; Douglas DC-4 replaces DC-3 in the Midwest-Florida study, DC-6 replaces DC-4 in December 1948 and the DC-7 is replaced on April 1, 1954. .

Its coverage increased significantly after four years, coupled with Chicago and the Southern on May 1.

Delta entered the jet age on September 18, 1959 with Douglas DC-8-10, followed by the Convair CV-880 in the short-to-medium sectors less than a year later. Despite the speed advantage achieved with Rolls Royce Conway engines, it was both shattered and thirsty.

A southern route authority granted in 1962 elevated Delta to transcontinental carrier status and enabled it to operate from Dallas to Los Angeles and San Francisco. Other service extensions include those from Atlanta to Jacksonville and Orlando, and to Phoenix and Las Vegas. Like the East, however, it remained mainly as an East Coast airline.

In 1965, the DC-8 and CV-880 were replaced by the Douglas DC-9 dual-jet in the short-range, low-capacity US domestic sectors, offering a very large and more-range.

The broader period of the carrier was beginning with the McDonnell-Douglas DC-10-10 to provide the necessary capacity to provide the required capacity during the Lockheed L-1011 delivery delays two years later in 1970 at the beginning of the next decade. .

Boeing purchased 727-100 tri-jets, which bought Northeast Airlines on August 1, 1972, to obtain highly demanding solar routes, and served from Miami to Montreal and Boston to the Bahamas. in Bermuda and Nassau and Freeport was able to count. network.

Atlanta, Boston, Chicago, Cincinnati, Dallas / Ft. A decade later, Worth is the third largest carrier to carry 34.7 million passengers in Fort Lauderdale, Memphis, New Orleans, New York and Tampa, Delta, 1979, and to 1300 flights daily to 80 destinations in the United States, Canada, Bermuda. carrier. , Bahamas, Puerto Rico, United Kingdom and West Germany. The motto is, "Delta is ready when you are" suitably.

Pan Am's growth has accelerated exponentially with European routes and Western Airlines' purchases. The system made more than 1,200 take-offs of 380 aircraft in 42 US states, the Columbia Region, Puerto Rico and 11 foreign countries, as evidenced by the volume's 433-page 1 July 1988 edition of the timeline. Mainly located in Atlanta, Cincinnati, Dallas, Los Angeles and Salt Lake City centers include Canada, Bermuda, Bahamas, Mexico, Ireland, Great Britain, France, Germany, Japan, Korea and Taiwan.

The highly mixed fleet of Boeing, Lockheed and McDonnell-Douglas included 727-200s (12 first class and 136 passenger bus passengers), DC-9-30s (12F and 86Y), 737-200s (12F and 95Y or 8F and 107Y). DC-10-10s (36F and 248Y), L-1011-1s, -250s and -500s (32F and 270Y, 12F, 54C and 203Y, 12F, 40C and 189Y) and 18F, 64C and 140Y) , MD-88s (14F and 128Y), 737-300s (8F and 120Y), 757-200s (16F and 171Y), 767-200s (18F and 186Y), 767-300s (24F and 230Y) and DC-8-71s (18F and 194Y).

The emphasis was on the minimum number of aircraft types to reduce fleet standardization and crew training, maintenance and spare parts stocks, but the emerging megacarriers & continents and continents from the 100-kilometer feeder sector, such as the Delta, which, by definition, serve each route length and density. An integrated airline had to do the work of many people: suburban, major regional, US citizen, major and megacarrier.

As a result, the four major US regions operating as Delta Connection have made a total of 3,900 daily departures over and above the Delta mainline flights to 240 cities and the DHC-7, SD3-60, EMB-120 and EMB-110 & apos; 27 with Business Express, SD3-60, S-340 and B1900), S-340 with Comair, Fairchild Swearingen Metros and EMB-110 and EMB-120s with Skywest and Swearingen Metros.

Delta, the world's largest TriStar operator with three versions and two sub-variants, described it as the “queen of the fleet ver and placed its first order to the 24 L-1011-s to complement its existing DC-8 in 1968. Nevertheless, to offer extended, broader user convenience and quieter, more efficient, more efficient bypass-rate turbobanes, advertising on one occasion, "the spectacular new $ 18 million TriStar, the newest member of Delta Air Lines' wide driving fleet." The rival DC-10-10 abandoned most of its other US carrier competitors, including America, Europe, National, Northwest, America and the West.

Due to the end of the bankruptcy program, Rolls Royce forced five McDonnell-Douglas machine parts to run intermittently, ultimately being sold back to the United States, even though it was rented back in 1972-1975. told. Their capacity increased the demand.

The first L-1011-1 registered to the N701DA is configured for 50 first and 200 passengers. However, between the years 1973 and 1983, 40 more acquisitions were just the beginning of a kind of history that proved to be synonymous with the Atlanta-based operator.

As the route system consisted mainly of short to medium range sectors, it passed through the air for about two hours at a time, connecting less than 1000 miles of cities.

It was supported by two L-1011-100 hired from TWA, from Atlanta to London-Gatwick, which exceeded the range of the first transatlantic route award, and eventually settled in Frankfurt and Tokyo.

In 1980 it received the delivery of three intercontinental L-1011-500s.

The used TriStar purchase program was comprehensive. Fourteen L-1011-500 (six from Air Canada, three from Pan Am, and five from United) were purchased between 1984 and 1992, and ten L-1011-1's East & West. It was purchased between 1991 and 1992.

In addition to renting two L-1011-200s powered by RB.211-524B engines, it changed an L-1011-1 to -200 standard and the remaining six to -250 configurations, enabling each of them to operate longer-range sectors.

In the summer of 1992, which served as a means of serving European transatlantic routes from Pan Am, up to 80 flights daily, the -500-type regularly made 5,774 miles of Anchorage-Hong Kong-Pacific crossing. The Longest.

Although budget constraints prevented Lockheed from proposing things that could replace the exact change in the stretched L-1011-400 format, it continued to determine this type of Delta's route system until the end of 2000, when only a 30-day flight was counted for the TriStar service. Boeing 767-200, -300 and -400 and MD-11, perhaps progressive changes that have emerged as McDonnell-Douglas' superior victory for Lockheed.

Delivered for the first time in November 1979, the L-1011-1 aircraft N728DA made its last scheduled flight from Atlanta to Atlanta and on July 31, 2001, after contact with Georgia soil. Couple is back taking water polo salute. During his career he had flown nearly 31,000 flight cycles, 66,000 hours and more than 27 million miles.

At the end of the Delta, 70 TriStar of all versions it operated for more than a quarter century represented 30 percent of Lockheed's total production process.
