For Sandy -- I'm the author and, while it's true that AEB was mightily p'd off with my first draft of the initial chapters, he came round and in the end there were only minimal changes. I'm told that, in the end, he ordered a bunch of copies for himself.
As for the facts, no-one's picked up any errors with me so far. And it's always the first question I ask if someone tells me they have it.
Writing it was a great experience. If I'd known how diverse an operator BHL was, esp in the early 80s, I would have signed up for a N Sea apprenticeship on the spot. As it was, I figured I'd done my time flying over the sea and joined Alan Mann. I had that Bobby Davro in the back of my helicopter once.
