I suggest you go and buy a packet of sliced Swiss Cheese and kiss that last slice for not allowing all the holes to line up again. Unless you guys lift your standards significantly though, those holes will eventually line up and claim some poor unsuspecting people their lives.
The point I am making is the red stop bar lights were the last slice in the Swiss Cheese. Again it prevented what could have been a fatal accident. Any reputable airline strives not to go near even the first layer while it would appear your airline is quite happy to use it as an error filter.
