Probably the contagion risk associated with airlines: AIZ, VAH's parent company had a similar issue with its pilots in Australian airspace on a Perth to Auckland flight see below:

Mind you Air NZ had their brush with similar issues in May last year on a Perth to Auckland flight see below:

In the European Union, German Workers Council representatives would not let a similar incident from Lufthansa into the public domain (unless fatal) on say Der Spiegel, perhaps in Australia, the pilots union might be similarly disposed. In NZ, even a minor brush is reported on stuff.
Bit of SP pressure on QAN, VAH and AIZ but it will more than likely blow over. I hope their hedging their POO exposure.
