It is an interesting question really.
There are a heap of QANTAS 74 and 76 Captains running around that had no real command experience when they got their initial jet commands - HEAPS of jet time, many years in the company - but very little command time.
Before you all jump down my throat and tell me that is rubbish..
How does a QF cadet get the experience to get a command - when ALL bar a couple of hundred hours is time in a QF aeroplane?
