My dear cloven hooved porcine friend,
What? Not good enough to be a pilot?
Those with poor observer scores but great pilot scores will get offered pilot and vice versa whilst those with good pilot and good observer scores are generally offered Observer first - of these people those that turn it down generally get offered pilot later.
Your depth of understanding in maritime matters and those pertaining particularly to the Merlin is obviously lacking - do you have this attribute in other areas of your life ? If so can I play you at heads up poker ??
