I think that deep inside, most of us know that this is a huge over-reaction. However with our modern society so scared stiff of litigation and risk of any nature, it is an entirely predictable and understandable consequence of current circumstances. Pressure will inevitably grow from airlines, tour operators and all businesses with a financial interest in aviation to get aircraft back into the air. National governments will be reluctant to succumb to that pressure putting the the problem into the same category as terrorism - ie no compromise; but, time will come when the situation changes to such an extent that someone will break ranks.
