If you live in the UK and prefer to watch Thunderbirds off the air as opposed to on DVD, I have good news. Every weekday at noon, BBC2 is broadcasting the show. First episode aired on Thursday July 27th with the pilot episode, "Trapped in the Sky".
Apparently, it is being broadcast in s-t-e-r-e-o which may mean that rather naff version with the cheesy surround sound effects. If you missed the first episode, fear not tomorrow is another day and of course, another episode.
