Most of Australia's aircraft are old. The qantas 747 that is parked at longreach had flown over 90,000 hours.
Most of our military aircraft are as old as, the GA fleet.
Virgin has the young aeroplanes.
But the pilots are getting younger.
And the accident rate seems to be related to the age of the pilots, not the aeroplanes.Remember the TV commercial." Young drivers are the most skilled. They are also the most killed".
