In such a weather condition all the noise/political agreement must be overcome.
Another time we have to wait till an aircraft is crashed for some action from people flying the desk (Guv, take note).
Why we attend classes of CRM and study lots of terms (situational awareness, ..,)?
To escape from Pilot Induced Errors?
I flew all the approaches in ZRH (all types and RWYs) with different a/cs, also with RJs, but as a prevention I think that the 22.00 overflights rules should be disregarded in such weather conditions.
My condolences and symphaty to all Swiss pilots and families.
Cheers.
