Overheard in standards office at a long ago jet refresher school:
Senior QFI has just completed a FHT on V senior officer and is completing " assessment of ability" on report.
QFI looks at VSO then writes Ab. which he then crosses out and writes "average".
Hang on, says VSO, you were going to write "above average", why the change of mind?
No sir, says QFI, I was going to write abysmal but I couldn't spell it !
