Overall a good collection of interesting SF tales, but some are missing, not many but it's worth mentioning. Some early episodes in the dozen range and more recently numbers 151 to 153. For example, The Destruction Factor is noted as 6 episodes. The first three are complete. Episodes 4 and 5 are missing. The final episode of that series, number 6 of 6, or 153 in the general numbering pattern, is only a minute or so long, so there's no way to find out what happened. I even did a Google and could not find the missing episodes. I did write to the podcaster a few months back and was promised it would be looked at, but -- anyway, overall it is a good job of gathering together older SF radio programs. Just needs a bit of double checking to make sure episodes get uploaded so they are complete and downloadable.
(BTW, The annoying intro music stuff really could be skipped. I hold down Fast Forward on iPod.)
