In this unhosted program, the second part of a film by the British Information Service continues the discussion of prehistoric civilizations in the United Kingdom with the bronze age. The iron age in Britain began around 3,000 years ago when the Celts invaded the British Isles. They brought with them the first wheeled vehicles. Remains of an ancient city and a recreation of a farmstead from this are shown. Part number from label.

In this unhosted program, a film by the British Information Service traces the remains of graves, temples, houses, tools and other possessions of prehistoric civilizations in the United Kingdom. During the Old Stone Age, men hunted wild animals with crudely made tools and lived in caves. When the ice receded in the New Stone Age, the environment and geography of Great Britain was much changed, and men became farmers. Archaeologists interpret this history based on findings at such sites as the Windmill Hill settlement in the U. K., which has yielded the earliest examples of British pottery. Scenes from Skara Brae in the Orkney Islands show the extensive remains of this prehistoric village preserved by blowing sand dunes. And Belas Knap burial mound near Cheltenham reveals the stone chambers and tombs of that period. This two-part program concludes with the Bronze Age, when men learned to produce metals and create more uniform tools, such as a cast ax head.

Lynn Poole recalls his first experience seeing an airplane. He then diagrams and explains jet propulsion, based on Newton's Third Law of Motion. A film by the British Information Service details the development of the jet propulsion gas turbine by its creators, Sir Frank Whittle and Captain Patrick Johnson, from its patent to its use in the air and sea. U.S. General H.H. Arnold arranged for the Whittle engine to be manufactured in the United States. A second film shows the July 15, 1954 maiden flight of the Boeing 707 Stratotanker/Stratoliner, America's first jet transport. In conclusion, Lynn Poole points out an article about "The Johns Hopkins Science Review" in the August 17, 1954 issue of the Saturday Evening Post.

This film by the British Information Service explains how British scientists of the Hydrographic Dept. of the Admiralty chart the seas. Since sands and shoals shift, charts must be updated for accuracy. The echo sounder on shipboard takes depths continuously by sending out sound waves, which are reflected from the sea bottom back to the ship. This is used in conjunction with the sextant's measured angles of landmarks on shore to fix the exact position of the sounding. The triangulation procedure is explained and demonstrated on land, including the use of an astrolabe, chronometer, and chronograph true bearing of the triangulation framework. For triangulation at sea, floating beacons establish baselines, soundings are made, and chart datum of tides' heights for a lunar month is collected. Cartographers then draw charts from the collected information.

This film provided by the British Information Service details the developmental history of marine radar. The creation of a plan position indicator (PPI), or radar output display, made shipborne radar possible. In 1946, the minimum requirements for radar equipment were established at an international meeting in London. A year later, the international standard for marine radar, built to withstand sea-going conditions, was set. This navigational aid saves time, money, and often lives. A ship entering the harbor of St. John, New Brunswick, Canada is shown using radar to navigate in the fog. Title from label on videocassette.
