May respectfully suggest that all crew go on a FACTORY training course ensuring that they fully and correctly understand the systems they are operating.
This post clearly indicates that the poster believes that "all crew" don't "fully and correctly understand...".
Would he have the decency to explain the whys an wherefores of this extraordinary accusation, and what evidence he has to support it?
Or else perhaps to apologise fulsomely for such an unwarranted slur against
the Professionalism of those crew alluded to?
For shame.
