Truss and control
If Truss admits he can't direct CASA, surely this gives credence to the Senator X submission to the AAI, aptly entitled, "WHO GUARDS THE GUARDS THEMSELVES"? Not Truss obviously! Senator X called for an Inspector General of Aviation Safety, with the powers, resources and expertise to oversee and independently review the activities of CASA and the ATSB. This position to be completely independent of the Minister and Dept.
In the current void of control, maybe this is the solution to sort out the current disgrace.
