Only serves to strengthen my view. QF and JQ no-fly decision is purely political. Absolutely nothing to do with safety and by that I mean responsible, intelligent, educated and informed risk management.
QF and JQ have Senate Inquiry and CASA hot potatoes to deal with and they want to spin whatever positive safety message they can as they simply do not want any heat associated with any form of ash event at all.
That, and they wouldn't mind another dollar off the share price, which'll help the their mates takeover.
