Yesterday's kit that can operate in hot and high conditions where the new kit can't.
Yesterday's kit that can be maintained in the field where everything points to the new kit requiring a huge and unrealistic maintenance tail.
Yesterday's kit that's affordable, both to buy and operate and far better suited to 90% of the helicopter's usual role than the new kit.
Yesterday's kit that Australia could afford to buy in such numbers that AAVN could support far more units than it can with a handful of hugely expensive "Rolls Royces".
Yesterday's kit that would allow enough units to be operated that crews could be trained in all aspects of their job before deploying.
Yesterday's kit that actually WORKS where the modern stuff has yet to do so after how many years is it now?
Yeah, a load of rubbish all that yesterday's kit.
