"The Adventures of Biggles" - a further look at the famous flying ace as he dictates a letter - opens the show.  Other features include a British climbing expedition tackling a well-known hazardous stretch of roadway; an urban household kitchen turned into a lifeboat; a special report on storage jars and their uses; the famed visit to a cheese shop that stocks no cheese; and a film critic who shows a clip from the Sam Peckinpah version of "Salad Days."
