A 'J' from Yesterday
Built in the 1930s the 'J' class yachts achieved a pinnacle of grace and beauty that has never been surpassed. Only ten were ever constructed - by the millionaires of the day - and most were broken up at the start of the war. Terry Brabent was determined that the 'J' class yacht should not pass into history. Bob Fisher charts a four-year struggle leading to the rebirth of the unique Velsheda.

Live coverage of an attempt by four climbers on the most famous chunk of rock in Britain. It's 17 years since Hoy was televised but the risks haven't diminished. Murray Hamilton and Pete Whillance will tackle the overhanging south-east edge, but without the protection of the bolts and pitons used on the first ascent. The rock itself, Torridon sandstone, has a tendency to crumble like a digestive biscuit. 'Falling off could mean our limited protection is ripped away like press-studs', says Whillance.
Also on the south face is the legendary Joe Brown , climbing with his daughter Zoe, six months old at the time of the first broadcast. Her climbing till now has been on small crags. At the thought of climbing 450 feet, with maximum exposure, she is, she says, 'absolutely terrified'.

Living in the far north west of Scotland and being faced with a journey of 180 miles to get vegetables, hotelier Robert Irving decided to grow his own. Using plastic tunnel houses he has become totally self-sufficient, producing high quality food for his customers and selling excess produce in the local area. Aided by expert John Molyneux he has developed several hydroponic units producing early crops of strawberries, french beans, peas and salads. Jim Sutherland ,

A Forty Minutes documentary
A flight of fancy about Britain's most underrated bird from some members of its human fan club: Naomi Lewis , the pigeons' Florence Nightingale who tends the stricken birds in parks and streets of London; Mr and Mrs Clapham who cohabit with 32 pigeons in their Tooting semi; Jed Jackson , the blind fancier whose 'Genista' won the pigeon Grand National in 1981; Geoffrey Stevens of Sheffield who trains his white fantails to take wing to the music of Messager in the ballet Les deux pigeons.
There is a man who eats them, another who dyes them and a journalist who panics whenever he sees them (he has never been to Trafalgar Square). Executive producer Roger Mills Producer Andy Stevenson
