John,
I lurk a lot and very rarely take the time to post but, having been involved in a documentary a few years back, I know just how much of a struggle the "TV effect" can be when you're trying to get things right. Suffice to say I thought you guys did a brilliant job with the documentary and managed to bring some tales of daring do to the sofa world of today very successfully. Good job, and please pass on all the congratulations you see here to the guys who made it. I know some of the researchers and runners work very hard on programmes like this for very little reward. BZ to all of them.
