I watched the program referred to. In fairness, it was more of a quickie which seemed to be aimed at kids.

Very much so. A programme that would probably whet the interest of sub-teens, some of whom may go on to search out more information and eventually finish up here.

Nothing that those with a greater breadth of knowledge will find particularly enlightening. Certainly worthwhile, and some of the air-to-air filming was good to watch in itself.
