The first of two programmes
David Lomax tells the story of the women from the Air Transport Auxiliary, whose dangerous task during World War II was to fly fighters and bombers from the factories to the RAF. Tonight: how the ATA was formed, how the women coped with the prejudice of the military authorities and how success was tinged with sorrow at the death of Amy Johnson , the first of many to be killed.

The 1984 Museum of the Year Awards with Sue Jay and Kenneth Hudson
Traditionally museums bring together a collection of valuable items and house them in grand municipal style. Many of the new museums go about things the other way round, by constructing a museum around the remains of an industry in the place where it was carried on. Two such new museums feature in tonight's programme: Sue Jay visits the Boat Museum at Ellesmere Port - established in old canal transshipment docks - and Kenneth Hudson visits the tiny Ruddington Framework Knitters Museum in Nottinghamshire, both successful candidates for one of the Museum of the Year Awards which recognises the best of museum innovation.
The Museum of the Year Awards are organised by NATIONAL HERITAGE in conjunction with THE ILLUSTRATED LONDON NEWS. Lighting MAURICE CARMAN

Presented by Professor Heinz Wolff Reaching the Heights
In which it transpires yet again that the world is mad and only the Egg Race is sane. Heinz takes the programme to Germany to find teams who will race over an obstacle course with the parts of a very tall structure. Finally, to riotous applause, they hoist three flags. Meanwhile the giant egg reaches its goal in The Incredible Egg Machine, with Lesley Judd. Only the salt and pepper have yet to be added.

Gladys Canavan is 71 and frightened of living in a ground floor flat in Belfast. So she turns to Sinn Fein and a young man arrives to help her. The fact that he has served six years in prison for an IRA arson attack doesn't trouble Mrs Canavan.
'He'll have learnt more about poor people than some of them at Queen's University.'
In just three years Sinn Fein has built a political machine whose grass-roots support threatens the non-violent nationalist party, the SDLP. The Northern Ireland Secretary, James Prior, is reported to fear that the Province could become 'ungovernable' if Sinn Fein's strategy succeeds. Could the political wing of the IRA win a majority of Catholic votes? And has the Government failed in its policy of isolating the terrorists?
