Having worked in engineering and having a modicum of common sense I find it somewhat pedestrian

I agree it's s bit corny in that respect, but just seeing the exhibits makes the programme worthwhile for me at least.
Pedestrian is a good description! This week we got second-by-second coverage of pushing of a Jordan F1 car from one shed to another! And as for the two blokes removing the sidelight from a Hillman wing using a hacksaw blade as a screwdriver, for a moment I thought I'd accidentally switched over to
Chucklevision.
But I am grateful for any programme like this and still look forward to it each week. Like RIchardV6, I love the glimpses of the exhibits.
