Danny, WO to Flt Lt was quite the norm except they still had to do the full brain adjustment at Cranwell. Did your WO do the full course?
No, what xenolith was asking was a scheme that came in around 2000 where the Cranwell course was about a week involving not much more than a new uniform and signing the papers. There were fairly tight age limits, time in rank, manning requirements etc. I think there was also a very tight limit on numbers. Typical shoe-ins were WO-PSF where they essentially just changed offices and carried on.
