Difficultly in answering a direct question!!!!
Your obviously a retired crewperson, Mr Trimpot.
In fact I was quite involved in the Civil Contract when I worked in the Eastern Suburbs of Sydney.
One thing that must always be asked and answered, particularly when other people's money is being spent, is valve for money.
The question that was asked and still remains unanswered, and is fundamentally central to the issue being discussed.
What return has the RAAF received for spending over 100 million dollars????
Any of their assets saved?
Any Airmen saved?
Any invaders repelled?
We all know the correct answer, even thou you seem to have trouble with the answer, or can't spell ZERO.
