Unless there's been an accident/incident, I have to agree that an external testing program is a huge waste. But, and I stand to be corrected; this silly system is not the unfortunate love child of CASA making. The way I heard it was some of the more loony political (left or right) religious zealot types wanted it done and after much pushing and shoving it was dropped in the ample lap of FF. I heard CASA wanted the 'doing' of it even less than we do; but then again, there's sort of inverted poetic justice in that....
Lots of companies have an 'internal' mandatory check before sign on, if we must have a system, why not leave it within the company, save a bundle and have an effective system.
