The Yak-42 trijet was developed as a replacement for Tupolev's Tu-134 twinjet and Antonov's An-24 turboprop.
The Yak-42 is an all new design although, like the Yak-40, it features a three engine configuration for increased redundancy and good short field performance.
The first of three prototypes flew on March 7, 1975. Development flying revealed the need for increased wing sweep back, and the change of wing sweep angle and suspected development problems with the new three shaft turbofans delayed service entry to late 1980.
Most production was of the initial Yak-42. The Yak-42D was introduced in 1989 and became the standard production model. It features increased fuel capacity, taking range with 120 passengers to 2200 km (1185 nm).

The An-72 was designed as a replacement for the An-26 tactical transport for the Soviet air force, but variants are in use as commercial freighters.
The first of five flying An-72 prototypes flew for the first time on August 31, 1977, although it was not until much later in December 1985 that the first of eight extensively revised preproduction An-72s flew. Included in this pre series batch were two An-74s, differing from the An-72s in their ability to operate in harsh weather conditions in polar regions. Production of the An-72/74 family continues.
Versions of the An-74 include the An-74A, the base An-74 model featuring the enlarged nose radome, the An-74T freighter, the An-74TK, 74TK100 and 74TK200 convertible passenger/freighter models, and the An-74P200D VIP transport.
The most significant design feature of the An-72 and An-74 is the use of the Coanda effect to improve STOL performance, which utilises engine exhaust gases blown over the wing's upper surface to boost lift. Other features include multi slotted flaps, rear loading ramp and multi unit landing gear capable of operations from unprepared strips.
Around 30 An-72s and 6 An-74s are in commercial use in 1998.

Despite a chequered early development history, the 50 seat ERJ-145 has become a runaway sales success.
The ERJ-145's first flight took place on August 11, 1995 with first deliveries from December 1996 to Continental Express. Continental's initial order for 25 was a major fillup for the program and opened the floodgates for a number of major sales. Continental at late 1998 held 75 firm ERJ-145 orders, while other major customers included AMR Eagle (42) and France's Regional Airlines (17).

The four engined Il-62 was the Soviet Union's first long range jetliner designed for intercontinental flights such as Moscow to New York nonstop.
The prototype Il-62 was first unveiled in September 1962. The Il-62 did not enter passenger revenue service until March 1967, with its first long range intercontinental service taking place in September 1967 when an example flew from Moscow to Montreal.
The improved Il-62M appeared at the 1971 Paris Airshow and introduced more economical Soloviev D30KU turbofans, increased fuel capacity and modified mechanised cargo holds capable of housing containers. The Il-62M entered service in 1974.

Tupolev's Tu-154 tri-jet remains the standard medium range airliner on domestic flights in Russia and other states of the former Soviet Union and to a lesser extent in eastern Europe and Iran.
The Tu-154 first flew on October 4, 1968. The first production example was delivered to Aeroflot in early 1971, although regular commercial service did not begin until February 1972.
Current production is of the Tu-154M, which first flew in 1982. The major change introduced on the M was the far more economical, quieter and reliable Soloviev (now Aviadvigatel) turbofans. Low rate production continues. Meanwhile the proposed Tu-154M-2 with two PS-90A turbofans remains unbuilt.

For many years the Tupolev Tu-134 was the standard short haul jet airliner in the Soviet Union and eastern Europe.
The initial Tu-134 design was based fairly closely on the Tu-124, and for a time was designated the Tu-124A. However Tupolev decided to reconfigure the aircraft to feature rear fuselage mounted engines and a Ttail, resulting in the new designation.

The One-Eleven can trace its origins back to the proposed Hunting H-107 jet airliner project of 1956.
British United Airways placed a launch order for 10 of the new jets, then known as the BAC-111, in May 1961. The new aircraft took to the skies for the first time on August 20, 1963, while the first production Series 200 first flew on December 19, 1963. Certification was eventually awarded on April 6, 1965, following a troubled flight test program, during which one prototype crashed with the loss of its crew, the cause attributed to deep stall from the rear engine and the T-tail configuration. With the deep stall issue resolved, the BAC-111 entered service on April 6, 1965.
The Series 500 introduced a 4.11m (13ft 6in) stretched fuselage and lengthened wings and greater seating capacity for up to 119 passengers. It first flew (converted from a -400) on June 30, 1967.
The Series 475 was optimised for hot and high operations and combined the Series 500's more powerful engines with the earlier shorter length fuselage.
The last UK built One-Eleven (by this time a British Aerospace product) flew in 1982, by which time production was progressively being transferred to Bucuresti in Romania where nine were built as the Rombac 1-11.
