Ok so test the flight deck, but then you have to test line maintenance who can do every bit as much damage if they want, ofh and while we are about it test the heavy maintenance guys too, err and all the inspections people, and, well the trolley dolls might be tempted to put sleeping pills in the flight deck coffee so better test them too , oh and the Board might overlook testing for a vital area of safety so lets test them too.
If you introduce something like this in accompany every one has to face same issues from the Chairman to the guy on the front gate and of course its an excellent opportunity for the 'leadership team' to actually show some leadership by example rather than pay packet, so how can anyone be against it .
