Gents,
We must be very careful when throwing in the flight safety card, it is our ace and if used routinely will lead to the retorts already mentioned in this thread and the erosion of it's value. If you have genuine concerns about flight safety then this is not where they need to be aired. There are valid points about the conditions we suffer, in varying degrees, being raised and it is good to share and learn from what others have to say but please, one day you will really need to use the flight safety card, lets hope you haven't worn it out.
