How many times does a potential life threatening “poor design” need to be pointed out before anything is done?
This is one of the worst things about "safety". You are not allowed to challenge the system. Quite often systems or airports are not design properly or corners cut to save money creating a safety hazard. When this is pointed out through safety reporting the safety department leaps to the defence of the system regardless to the obvious hazards. It isn't until there is a near disaster that the safety position is untenable and miraculously things get fixed.
