Moving House
Not all craftsmen are old men Adrian Hodgson is 35 and specialises in the removal and restoration of timber-framed houses.
He runs his own business from Holmes Chapel in Cheshire and regards such houses as immense pieces of furniture. Whether he's carving an elaborate chair leg or restoring a half-timbered church, he has the same sensitive approach as craftsmen of another age.

Pleased and proud, Blue is left in sole charge of the ranch. But it is a far tougher job than he imagined.

The 1930s were marked by brilliant advances in physics. By 1939, and the outbreak of World War II, British and American scientists knew that it might be possible to release the energy locked in the atom, with a new type of bomb. One of the questions uppermost in their minds was, 'Will the Germans get there first? '
This documentary record of the scientific and technological steps that led to the dropping of the first A-bomb includes interviews with scientists from both sides of the struggle, some who have died since the film was first shown ten years ago. When the bomb was dropped on Hiroshima scientists realised for the first time the complexity of the issues involved.
The dilemmas they faced are the dilemmas that still face scientists whose theoretical scientific research may be used to produce new weapons.
' There are passionate arguments - they do not persuade me one way or the other. At the time, the alternative campaign of invasion was certainly much more terrible for everyone concerned. (However) I think that Hiroshima was far more costly in life and suffering and more inhumane than it need have been for being an effective argument for ending the war. This is easy to say after the fact.'

Test Match highlights: England v Australia
Richie Benaud at Lord's introduces highlights of the fourth day's play.

'Although the pace of cricket is perhaps slower than many other TV sports, the basic tenets of commentary still hold good - the job is to identify, to illustrate and to illuminate...' David Kenning in Armchair Cricket 1975 (£1.25 from, bookshops)
