a lot of it is hard, and much of it dull
Yes it is a slog. But dull? Man! I learnt loads I wanted to know but never got around to asking. It is a bit of everything: geogaphy, met, physics, engineering, psychology and...um...that lateral seperation in MNPS airspace is 60nm...but we should gloss over that last one
Seriously, I found it more interesting than not.
