The brilliance of fine engineering
The BBC have been started a series on how things are made! The first episode was on the making of a nuclear submarine – perhaps not something that touches most of us!

But the second episode was much more the ‘touch of the common man’ as it was about the building of a commercial jet engine, the Trent engine built by Rolls Royce of Derby, England.
Anyway, I’m not going to natter on other than to say that not all regulatory bodies are bad in this world. Indeed, the aviation industry has shown how splendid both engineering and the certification processes can be in giving us a incredibly safe form of transport.
There are plenty of YouTube videos on the Trent engine but here are two that I found of great interest. (Thanks to Simon H for the pointers.)
