Are they ALL? Certainly not. Like any job, there's always a couple of tyrekickers out there. With NVG, because of the lack of civil experience with them, if ex-mil staff are employed, then there's a leap of faith taken by the company in question that this person isn't leading them up the garden path. In some cases, there is going to be companies led up unlit paths. In the majority of cases, this may only end up in embarassing dead ends. In some cases, with poor examples set by those trading on reputation rather than competence and experience, these paths can lead literally, to dead ends.
These are delicate times for the future of NVG operations in AS civil aviation. It will only take one serious incident or event in the short/mid term time frame for CASA to baulk at licencing additional companies. It's one aspect of flying that has to be done right, first time, every time.
