Thank you, I'm glad somebody finds my ramblings useful.
Interesting aside, I graduated in 1992 with a degree in aeronautical engineering - there were 63 on my course. I think that two of us are still in the industry (interestingly, the other one has my old job that I left 10 years ago). It's good to use all that education, but I do wonder about the other 61 sometimes. I still think that learning (and sharing and using that knowledge) about the most complex and fascinating machines the human race has ever produced has been a great way to spend the last quarter century.
Eventually I'll even understand how an aeroplane flies as well, but that may need another 25 years or so. That I've still got chalked up to magic.
