John Noakes aboard the Flying Scotsman

They don't make children's television like this any more.

I can remember Christopher Trace, who presented the show from 1958 to 1967. He was dropped in part for bedding a 19-year-old during a Blue Peter summer expedition to Norway. Biddy Baxter did not approve of That Sort of Thing.

Trace was exiled to BBC East in Norwich, which was still broadcasting in black and white as late as 1973.

According to a BBC profile, he was Charlton Heston's body double in Ben Hur.
