The Boy from Space is something of a cult viewing experience over here in Blightly, and having watched it today, I can see why. I will certainly be digging down into the shows many wonders although over on my Strange England blog, where it truly belongs.
For now though, I'll present this rather nifty spacesuit that appears in episode one, in the linking bits between the drama.
I'm fairly certain that helmet was in Doctor Who - The Invisible Enemy (1979) first, then The Innes book of Records (1979). After that at least one of them got a coat of silver paint before popping up in Blake's 7 - Voices from the Past (1979), Look and Read the following year and eventually, possibly Dr Who - Terminus (1983). What's the betting there are a couple more BBC appearances in between.
