Part 1
At the end of "Blue Peter"'s Silver Jubilee year a last chance to step back in time as Valerie Singleton takes an affectionate look at the highlights and landmarks from some 50,000 minutes of television.
There are thrills and spills as a succession of intrepid "Blue Peter" presenters climb Big Ben and power station chimneys, and swing from ropes across Tower Bridge - not forgetting the unexpected disaster when the Girl Guides' campfire nearly destroys the studio!
