Attack Fighter 2, you use a military sounding handle for your first post, and then attack the military with your second? Your conduct in two posts hardly engenders respect. You may not be any ones stooge but it still sounds like you have a vested interest.
The 707 was not the RAAF's finest hour by any stretch, it was at its heart caused by a loss of experience to the airlines. The RAAF also had a relatively high accident rate through to the late 90's, operations were far more aggressive than required and not always in a smart way. The continued and rapid loss of experienced captains to the airlines did not help. Australian commercial airlines on the other hand have an excellent safety record anchored around a high standard of entrant and high experience levels. Whilst the RAAF has lifted its game significantly in the last 15 years, and safety stats back me up here, commercial aviation appears to be headed in the opposite direction.
As for CASA, I have seen very dodgy practices in commercial aviation that CASA turns a blind eye to. To quote a CASA official "we are not a safety organisation, we are a regulator".
