Pembroke,
I try very hard not to be judgemental on these fora, but I have to say, if you're not a troll, you really should spend more time in your allotment.
Portions of your last post are just inane ramblings. "I asked for comments and deliberately put on this forum, not the one above." What ?
And as for the "CB story", it really does come across as if you're suggesting that the GPS would/should have warned the crew of the presence of a CB. Well, perhaps in the USA, old fruit, but not on these shores.
