I found the program really interesting from a mechanical point of view - e.g. are the springs in a sprag-clutch really that small
Not only did the program show the guy assembling the bits, it also had tours of the factory showing their CNC tooling etc. Quite reassuring to see the quality of the work being done, but still not sure I'd fly in one (especially if I built it).
Anyway, the program has a website if you're interested
here .
