I'm sure we're all very comforted to know that it wasn't a Security argument that brought down PI .......
An argument is an argument. It is standard aviation practice as a result to avoid arguments before flying duty. The current rules are made/enforced by people without aviation training.
We know the Security set up is not fit for purpose but we can't (yet) fix it because those who enforce Security procedures are working to a political agenda rather than a safety agenda. Hence this thread.
