If you liked that documentary, you might love this older one, which features Stanley Hooker. It's amazing to get the perspective of the legendary engineer himself, and it goes much more in depth into the technical problems and business challenges.

Haven't seen that before, hugely enjoyable and entertaining.

Another favorite aviation-related one, though more pop-sci-oriented, is this look at a 747 going through a D ("heavy maintenance") check that basically takes most of the plane apart and puts it back together, covering all the bits and how they need to work:

I agree also wanted to post it when I saw the article. Absolutely mesmerizing to watch.

I did not know that the fan blades are hollow nowadays! The way they are made is pretty mindblowing, thx for posting that link.

I've watched that a few times, never gets boring.
