Icarus' Children
The story of man-powered flight
To fly like a bird has long been a human ambition. To use an engine or to glide from a height is somehow cheating. It must be human-powered.
In 1959, British businessman Henry Kremer offered a prize, now worth £50,000, to the first person who could fly a prescribed figure-of-eight course. Tonight's film shows the various attempts since then to win the prize. Strange machines struggle to leave the ground. Some crash in a heap, some fail altogether. But the dedication of small, mostly amateur groups to overcome seemingly impossible problems is quite remarkable. One of them gloriously succeeds. The prize went to Californian Paul MacCready whose frail craft Gossamer Condor, after a long series of trials and mishaps, successfully flew the course on 23 August 1977.

Following the Tundra Wolf Narrator Robert Redford
In a straight race a wolf doesn't have a chance against a caribou; the caribou can reach 40 miles an hour, whereas the wolf can manage only 30. Nevertheless, in the Canadian North-West, wolves live mainly on caribou. So how do they manage? The answer lies in tactics: organisation and ambush. This film follows the epic spring journey of the caribou to their breeding grounds in the north-and the wolves that travel with them. It is the story of the delicate balance between predator and prey - and through remarkable aerial photography it shows just how the balance works.

Presented by Angela Rippon This week:
Otters and Otter-Hounds
Otter hunting is now a country pursuit of the past, but it is still uncertain whether the otter has an assured future. This charming native mammal is under pressure on all sides and it's doubtful whether the banning of the otter hunt has had any real effect on its well-being.
With her guests. Elizabeth Eyden , Gordon Benlngfield and Phil Drabble , ANGELA RIPPON looks at the natural history of the otter and the fate of the otter-hound, which, in spite of being put to work hunting wild mink, is now much nearer to extinction in Britain than the otter itself.
