Ex FJ backseaters
Not strictly true; on the first "orientation" course there were 2 FJ backseaters and one herc nav, who had done time with the RN AEW Seakings. The "orientation" course turned into the full 28 week (or similar-it's been a long time) course. Two passed (just, with "political" pressure applied) the course, but were subsequently either withdrawn from post-grad training or "sidelined" because they were not cutting the mustard. The third was promoted just as we sere deciding how much flex we could give him in order to try to get him through.
