There is an explosion in naturist holidays. It is estimated that 15 million people spent their holidays with nothing on last summer - four times as many as ten years ago. One tour operator predicts that naturist holidays will soon be as popular as ski-ing. At Cap d'Agde in the south of France a gigantic naturist town is being built. Already it has accommodation for 20,000. Soon it will be twice the size. And its supermarkets, banks, cafes and restaurants are full of naked people English families explain why they choose to go naked - many preferring the less commercial, back-to-nature resorts; few approving of the Mr and Miss Nude Admerica pageants staged every year by a Californian entrepreneur ' to bring nudism out of the closet and into the public eye '. JOHN PITMAN traces the growth of the naturist movement this century, from its small-time beginnings in a park in north Germany, to the multi-million-pound business it is today - especially for France and Yugoslavia.

A trade information film about an exciting modern extra for TV.

This highly informative and educational two hour BBC program was written and conceived by Nigel Calder, author of several books on science, including Einstein’s Universe, upon which this program is based. It is hosted by Peter Ustinov, who serves both as our guide to understanding Einstein’s theories and speaks Einstein’s words to make his presence felt throughout the program. Ustinov becomes educated in Einstein’s theories by many of the best minds in science, who provide demonstrations to illustrate his teachings. These include experiments to help understand gravity, warped space, how light responds to gravity, the “Doppler effect” and how radio waves, as used in police radar, are an unbeatable way of measuring speed. From these simpler experiments much larger concepts are drawn, such as the discovery of a Binary Pulsar, the nature of black holes and how they are created, and the ultimate theory of how the universe was formed. Other demonstrations measure the speed of light, how time passes more slowly for people traveling in an airplane, the incredible accuracy of the Atomic Clock in Washington, DC and how time itself would appear to stop at the surface of a black hole. The conclusion of the program portrays Einstein as a great humanitarian. Although known as the “father of the Atomic Bomb”, his greatest concern was for the potentially devastating effects splitting the atom could have on the future of mankind. His famous letter to President Franklin Roosevelt warned that although the splitting of the atom to detonate an atomic bomb could be used to end World War II, it could also potentially be used for far more deadly ends. This last thought is the subject of another Nigel Calder book, Nuclear Nightmares, and a second BBC program to explore this subject in more depth.

TV special featuring footage filmed throughout Wings' tour of 1975/1976, following the band in England, Australia and America. It contains live concert performances featuring fifteen of Wings' greatest songs and home movies of Paul McCartney and his family, providing a fascinating profile of the McCartneys' life off-stage. The tour itself was a major triumph for Wings - the first time the group had appeared in Australia and America, and Paul's first performance in the States for ten years. Three million people saw the shows and a then-world record attendance for an indoor concert of 67,053 was set at the Kingdome, Seattle. Starting with Paul and Linda in Scotland, the special features the gradual build-up of the band and follows Wings on tour with hit songs such as Jet, Maybe I'm Amazed, Yesterday, Silly Love Songs and Band on the Run. The Wings line-up for the tour was Paul and Linda McCartney, Denny Laine, Jimmy McCulloch and Joe English.

James Burke looks back on the Apollo Moon landings, following the astronauts' version of Apollo earlier this evening, this second programme goes right behind the scenes to examine the political imperatives that first fostered, then disowned Project Apollo. Born out of J.F.K Kennedy's frustration at Soviet success killed because of the cost of the Vietnam war, Apollo was a political football - as the top NASA managers reveal in exclusive interviews. Lunar scientists, too, have a story to tell. What, after ten years-analysis of moon rocks, did they get out of the $24-billion adventure? What, come to that, was in it for the rest of us?
