Tourist - Thank you for your kind comments. I do take time to look at people's profiles, can't comment in detail on open parts of the forum, but I tend to put greater weight on the comments made by those who show relevant experience.
I have apologised several times for believing Mr Exascot's post about tax-free status, his use of irony was so immaculate that it passed me by. Nice one, Exocet!
I do believe Mr Courtney Mil's comments because they are reasonable and because they are in accord with what I have seen from within the industry. Oh, how many tales could I tell, were I free so to do.
Several books have been written on Murphy's Laws, which apply very much in the design of those machines best described as 'a collection of engineering compromises flying in close formation'. Highly recommended.
