Of interest on the last two occasions that I have attended a function at units where my son has been stationed I have sat next to a pilot who has rejoined the RAF having spent a period working for an airline. Both cited the same reasons for rejoining; lack of stimulation, lack of comradeship and poor working conditions. It seems to me that this is not a one way flow and it would be interesting to see some stats on the numbers of pilots who rejoin and how long after retiring.
