BASIC INFORMATION ABOUT DC-9
The Douglas/McDonnell Douglas DC-9 is a twin-engine, single-aisle jet airliner. The DC-9 was designed for short to medium routes, often to smaller airports with shorter runways. DC-9-based airliners including the McDonnell Douglas MD-80, MD-90 and Boeing 717 (MD-95) later followed in production. The DC-9 is one of the longest-lasting aircraft in operation. Its last successor, the Boeing 717, was produced until 2006.
The first DC-9 flew on February 25, 1965, and the first DC-9 entered service with Delta Air Lines on December 8, 1965. The DC-9 was always intended to be available in multiple versions to suit customer requirements. There are five basic DC-9 versions, designated Series 10, Series 20, Series 30, Series 40 and Series 50. Several models in each series provide operators maximum efficiency for diverse combinations of traffic density, cargo volume and route distances. The DC-9 was a commercial success with 976 built when production ended in 1982.
The DC-9 was followed by the introduction of the McDonnell Douglas MD-80 series in 1980. This was originally called the DC-9-80 series. It was a lengthened DC-9-50 with a higher maximum takeoff weight, a larger wing, new main landing gear, and higher fuel capacity. The MD-80 series was further developed into the McDonnell Douglas MD-90 in the early 1990s. It has yet another fuselage stretch, an electronic flight instrument system, and completely new International Aero V2500 high-bypass turbofan engines. The final variant was the McDonnell Douglas MD-95, which was renamed the Boeing 717-200 after McDonnell Douglas's merger with Boeing in 1997, and before aircraft deliveries began.
The worst accident to DC-9 happened on September 10, 1976, when Inex-Adria Aviopromet Flight 550 collided mid-air near Zagreb, Yugoslavia with British Airways Flight 476. The collision was the result of a procedural error on the part of Zagreb air traffic controllers. The Flight 550 was operated with DC-9-31, and the Flight 476 with Hawker Siddeley HS 121 Trident. Both planes crashed after collision, and were destroyed. All 176 people aboard both aircraft and another person on the ground were killed. 113 of these fatalities were on board DC-9, which makes it the world's deadliest air disaster involving the DC-9.

BASIC INFORMATION ABOUT MD-80
The McDonnell Douglas MD-80 is a series of twin-engine, short- to medium-range, single-aisle commercial jetliners. It was lengthened and updated from the DC-9. The series includes the MD-81, MD-82, MD-83, MD-87, and MD-88. These all have the same fuselage length except the shortened MD-87. The MD-81 (originally known as the DC-9 Super 81 or DC-9-81) was the first production model of the MD-80, and apart from the MD-87, the differences between the various long-body MD-80 variants are relatively minor. The four long-body models only differ from each other in having different engine variants, fuel capacities, and weights. The MD-88 and later-build versions of the other models have more up-to-date flight decks featuring for example EFIS.
The first MD-80 made its first flight on October 19, 1979. The first delivery, to launch customer Swissair took place on September 13, 1980.
The worst accident to MD-80 series aircraft happened on December 1, 1981, when Inex-Adria Airways Flight 1308 crashed on Corsica's Mont San-Pietro, killing all 180 people on board. The aircraft was a McDonnell Douglas MD-81. The aircraft's first flight was on May 15, 1981, and the aircraft was delivered to Inex-Adria Airways on August 11, 1981. The aircraft only had 683 flying hours at the time of the accident. The crash was the deadliest and first major aviation accident involving a McDonnell Douglas MD-80.

BASIC INFORMATION ABOUT MD-90
The McDonnell Douglas MD-90 is a twin-engine, short- to medium-range, single-aisle commercial jet airliner. The MD-90 was developed from the MD-80 series. Differences from the MD-80 include more fuel-efficient International Aero Engines V2500 engines and a longer fuselage. The aircraft first flew on February 22, 1993, and the first MD-90 was delivered to Delta Air Lines in February 1995. Following the MD-90 in the DC-9 family was the MD-95, which was renamed the Boeing 717-200 after McDonnell Douglas merged with Boeing in 1997.
