A jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by one or more jet engines. Whereas the engines in propeller-powered aircraft generally achieve their maximum efficiency at much lower speeds and altitudes, jet engines achieve maximum efficiency at speeds close to or even well above the speed of sound .
The following is the list of purpose-built passenger jet airliners.It excludes turboprop and reciprocating engine powered airliners. It also excludes business jets and aircraft designed primarily for the transportation of air cargo.
Jet airliners that entered service in the 1960s were powered by slim, low-bypass turbofan engines, many aircraft used the rear-engined, T-tail configuration, such as the BAC One-Eleven, Boeing 737, and Douglas DC-9 twinjets; Boeing 727, Hawker Siddeley Trident, Tupolev Tu-154 trijets; and the paired multi-engined Ilyushin Il-62, and Vickers VC10.
The Jet Age is a period in the history of aviation defined by the advent of aircraft powered by jet turbine engines and the social and cultural changes fostered by commercial jet travel. Jet airliners were able to fly higher, faster, and farther than older piston ‑powered propliners , making transcontinental and intercontinental travel ...
Jet aircraft use airbreathing jet engines, which take in air, burn fuel with it in a combustion chamber, and accelerate the exhaust rearwards to provide thrust. Different jet engine configurations include the turbojet and turbofan, sometimes with the addition of an afterburner. Those with no rotating turbomachinery include the pulsejet and ramjet.

The English Electric Canberra is a bomber aircraft powered by two jet engines, and able to fly at high altitudes. An early prototype operated by Rolls-Royce regularly flew to 63,000 ft, where the usable speed range (coffin corner) was only 25 knots, during Avon engine test flights. [38]
The first successful jet aircraft, the Heinkel He 178, flew only five days before the war started on 1 September 1939. [1] By the end of the conflict on 2 September 1945 [ 2 ] Germany , the United Kingdom, and the United States all had operational turbojet -powered fighter aircraft while Japan had produced, but not used, motorjet -powered ...
