Space Force Two (ep5/6) Living with Death

Space Force is a BBC Radio science fiction serial, broadcast from 4 April 1984 to 17 June 1985.
Written by Charles Chilton, it was originally intended to be a sequel to his Journey into Space series (broadcast in the 1950s), using the cast which had just made a one-off revival of that series ("The Return From Mars"); while this idea was dropped late in the development of the serial, the four characters are nevertheless essentially the same as those from the earlier series, albeit with different names.
The first series begins during the northern summer of 2010. Both series seem to initially mirror the first two Journey Into Space stories before branching off into quite different plots.
A second series, known as Space Force 2, featured the same main characters, once again played by Barry Foster, Nigel Stock, Nicky Henson, and Tony Osoba.
Within both series, Space Force is the name of the team's spaceship, rather than the name of an organization.
Each episode had an approximate run-time of 30 minutes.
