Garry Halliday episode guide

I've posted the first two entries in what I hope will be an exhaustive guide to Garry Halliday, a BBC serial about the adventures of an airline pilot created by Justin Blake (i.e. John Bowen and Jeremy Bullmore), that ran between 1959 and 1962.

The BBC made 50 episodes, only one of which survives. But Doctor Who was devised to fill the same Saturday teatime slot and I think owes a significant amount to Halliday, which I'll tease out as I go through the history.

As with Doctor Who, there were novelisations of Garry Halliday's TV adventures. I now have copies of all five Garry Halliday books, and have already posted reviews here of the first three of them:

• Garry Halliday and the Disappearing Diamonds (1960)
• Garry Halliday and the Ray of Death (1961)
• Garry Halliday and the Kidnapped Five (1962)
