Chris Serle, in this week's exploration into the biggest film and videotape library in the world, discovers what transport means to Robbie and a flying boat, Basil Fawlty in Fawlty Towers and a Weed in The Flowerpot Men. There's classic comedy from Sykes and a Bus and a Bus Strike in 1946 that seems like a holiday. From Nationwide there's a vicar with a wheelbarrow, and even a Churchmobile. There's trouble on a train in Telegoons: The Hastings Flier with the voices of Peter Sellers , Harry Secombe and Spike Milligan. Guest traveller Alan Whicker tells tales of Tonight, when he was Whicker Down Under, and of the time he stopped a train in Whicker on Top of the World. You can even prove that dogs on skateboards go in anything but straight lines. Producer MIKE SEDDON Series producer ALBERT BARBER
