To mark the 30th anniversary of Back to the Future in 2015, Radio 4 commissioned a special ten part series of programmes with Peter Snow and some of our most interesting thinkers and journalists.

The question: if you could go anywhere in history, either backwards or forwards in time, where would you travel to and why?

In the first part of this hour long omnibus, Peter Snow clambers into a time travelling DeLorean to take his guests on temporal trip, with contributions from MP Alan Johnson, geneticist Steve Jones, space scientist Maggie Aderin-Pocock, travel writer Simon Calder and historian Kate Williams.

Producers - Caitlin Smith, David Stenhouse and Mark Rickards. Show less
