Hey Silver, yeah that way they'd know that they were going to spend some of their service at sea. But why stop at pilots? The aircraft need a team to look after them so all the crew would have to be 'Naval', no use training the pilots but have the techies posted down from the 'Don, that's not a good combination! As I said in another thread, I left in '85 'cos I didn't fancy working 3 weeks at sea as we were told that would be a typical patrol.
