My course started with 24 RAAF/RAN and 10 Army.
12 RAAF/RAN passed 2FTS and 4 Army passed Kiowa conversion.
But that was back in the day when course was actually hard and 2FTS was not a sausage factory
To people who say if you work hard enough anything is possible.... Its just not true, there were some guys on my course who worked like mad men studying every spare moment. You either have it or you dont.
