I liked his "Plane Crazy: Building a Plane in 30 Days" on PBS.

Watching him try (and fail) to build a composite airplane says so much about the allure of modern techniques (I won't spoil the end, but old-school gets the last laugh). I've been less than enthusiastic about modern composites ever since seeing this show.

Bob's attempt (and short temper) reveals a good deal of hubris on his part.

The documentary is a fascinating failure and a masterclass in attempting to salvage a show when the whole premise for the show completely collapses.
