How sad thatNavigators are no longer with us. In my days in the fifties in Coastal, all pilots had to do a navigation and maritime course for three months on Lancaster’s at St Mawgan before going to Kinloss on Neptune’s or Shacks. There were two Navs on each trip, one qualified N and one pilot u/t Nav. After all the hard work passing the Nav part of the course, I was determined that when I got my own crew, I would do the odd leg as Navigator It was not to be as all the logs and charts on the Squadrons were checked and marked, so, even as Captain I was not allowed near their precious charts! - only to check where we were - no touching !. I am still in touch with my first Navigator, also very old , one co - pilot and one Signaller, all from my first crew. All the others have “ taken off”. How will the new jets cope with Maritime. Automatics do go u/s.
