My #2273 refers.
Checking my Kit List - find I've left an open goal - What about the "White Flash" ?
As I recall, it was a small piece of some light felt-like stuff which fitted in the fold in front of your forage cap. It was issued to all aircrew trainees and they wore it throughout their training. It really signified "potential officer": it was akin to the Sandhurst white capband or a Midshipman's white patches.
We all wore it with immense pride, even though we knew that, at the end of our training, only some 20% of pilots and navigators (and a much smaller percentage of the other aircrew trades) would receive Commissions. The remainder would be promoted from LAC to Sergeant.
Another matter:
I have read various figures quoted as pay rates. I am quite certain what I was paid (all rates per day): AC2 : 2/-, LAC : 5/6, Sergeant-Pilot : 13/6. All subject to deductions like "Sports subscriptions" (what on earth were they ?), Barrack Damages and Voluntary Allotments
to a family member.
