RAAF Pilot
Taimoor,
The first principle of war is selection and maintenance of the aim. You must decide exactly what you want and do everything possible to achieve this. Part of this might be to decide on an all or nothing approach. An AEA NCO is not exactly a commissioned officer and pilot.
My understanding in 1962 was that it was more certain to be a RAAF pilot from day one, rather than hope for it later. I held this belief during the 8.5 years of my service and my subsequent airline career.
If you cannot hold true to your dream, you will be less deserving of RAAF pilot wings.
