2. Read the text from the history of aviation. Jet propulsion

The development of jet propulsion is considered by many to be the greatest advance in aviation since the first flight of the Wright brothers.

Frank Whittle of Britain operated his turbojet engine with success on April 12, 1937, but it was not until August 27, 1939, that the world's first jet plane, built by the Germans, was flown.

On May 15, 1941, the first British jet was flown. It was powered by a 860 pound-thrust Whittle turbojet.

The Bell Airacomet was America's first jet plane. It flew on October 1, 1942.

It was Britain that led the world in the development of jet propulsion after the end of World War II. Less than four years after the War, Britain was flying the de-Havilland Comet, powered by four turbojets and the Viscount, powered by four turboprops. The passengers received a smoother flight and also a shorter ride due to a higher cruising altitude and increased speeds. The jets could now climb above most of the turbulent weather.

The Soviet Tupolev TU-104 was in wide use during the latter months of 1958, and America's Boeing 707 and Douglas DC-8 aeroplanes soon were transporting passengers across the Atlantic.

Mass travel became so popular that aircraft designers increased the size of many passenger aeroplanes, and even larger ones are being planned. At present up to 490 passengers can ride in the Boeing 747s. Other wide-body aircraft include the MC Donnel Douglas DC-10 and the Lockheed 1011.

The aircraft industries of Britain and France have produced a supersonic airliner capable of speeds up to 1450 mph. If one goes by the clock, passengers on the Concorde could land in America before they took off in Europe.
