Tolerance
Don't understand why some have an axe to grind with people who enjoy watching planes. Some countries take positive steps to allow people to do so. As an example, at the northern perimeter of Zurich airport, there is a large free parking area served by refreshment vans where anyone can enjoy aircraft approaching runways 14 and 16. And if you are prepared to walk a short distance, you can even look through the fence down the length of runway 14.
There is also another facility allowing great viewing of departures on runways 16 and 28. Why are the Swiss more tolerant than most UK airports?
