Rats. The RAAF was clearly the prime cause of the delay by not allowing the pilot to file a plan for the shortest and safest route
Even the Air Marshal in his press release says delays can be reduced by filing a flight plan on the route - he clearly had not been informed this is prohibited .
This route limitation was solely introduced by the RAAF.
Do the flight today and you must file on the western route..that means that the Willy ATC will have no details on your flight and there will be a delay if you call for a different clearance to the flight planned route.
Are you willing to risk a repeat of this accident rather than support a removal of the RAAF restriction?
