Slalom Lager Premiership Final 'Six days shalt thou labour and do all thy work', it says in the good book. What it doesn't say is that the seventh is the Premiership Final. It's live from Leeds at
3.0. It'll be HALIFAX or LEEDS against WARRINGTON or WIGAN. It's certain to be RAY FRENCH and ALEX MURPHY. There were ten tries last time, you know.
Cricket
Leicestershire v Lancashire
Sixth and 14th respectively in last year's John Player

Just-in-Time: the well-stocked warehouse and the factory floor full of parts might seem like the hallmark of a prudent company. Not any more. 'Just-in-time' is a new philosophy that's cutting back the E41 billion of stocks in Britain's factories - and producing remarkable results.

Flying Round Alone
'Looking back. I realise how lucky I've been to avoid disaster on at least six occasions.'
Dick Smith is an Australian self-made millionaire who had a dream - to be the first person to fly a helicopter solo around the world. He collected his machine - much modified for endurance flying - from its Texas factory and set off across some of the most inhospitable terrain on earth - ice, tundra, mountains, oceans, deserts. Along the way he dropped in on Balmoral, made a forced landing in the Burmese jungle and successfully located a ship 700 miles out in the Pacific - to pick up fuel.
And as if that wasn't enough. he made a film with sound of himself (and by himself) of this unique world voyage.
Filmed and directed by DICK SMITH Presented for BBC by TONY SALMON Series editor TIM SLESSOR
