Grounded

I wonder if, with all the planes in Europe grounded for an unpresidented 6 days, there was any change in things like sunsets, UV, stress and the like? Obviously some people were substancially more stressed, as they sat stranded here and there around the globe, or waited for a loved one to return safely...but I wonder if people unaffected had a somewhat lessening of stress from the removal of the noise pollution associated with air travel?

Im sure research was done.

let me know if you find any.
