Just a shame no journo asked Alan the following....
If the grounding of the qantas fleet created an imminent safety risk, (as determined via your internal risk assessment) and aircraft either taxiing, lined up or about to push were told to return to blocks,
Why were aircraft that were airborne at the time, not told to landed at the nearest suitable airport?
Was there somehow different levels of imminent safety risk identified in the risk assessment? If so, please explain?
So many questions Alan.
