Re Green Shield Flt Lts, in the early '70s, University Entrants to RAFC received an increment if they'd achieved a First. But had to do 6 months as Plt Off before the promotion kicked in. As there were 4 entries per year, this meant that some arrived on the last entry of the years to start IOT as Flt Lts without having done previous time pre-university as Flt Cdts.
One chap on 17 GE actually outranked his ex-supplementary list blanket-stacker flight commander, who was only an acting Flt Lt..... Fortunately they both saw the funny side of such a system.
Another, with increments for having been an ex-App and having also been a Flt Cdt, never served any time as a Fg Off - due to the 6 month thing, he went straight from Plt Off to Flt Lt.....
