Seeing all the Doctor Who discussion on the forum, I thought some of our DVD Verdict readers might like an introduction to one of the Doctor's predecessors -- explorer Jet Morgan.

If you go to the BBC 7 online -- www.bbc.co.uk/bbc7 -- and check out the Saturday "Listen Again" feature, you can hear a classic episode of Journey Into Space.

Each season is a 20-episode serial. The first couple of episodes have already been aired, but it should be easy enough to follow. In "World in Peril," Jet and his team have returned from Mars, only to find out that Mars is invading Earth.
