After reading the posts about JET2 not landing at DAM due to weather it reminded me of being on the runway at Zurich and the snow clearing effort that was going on.
I was on an EZY flight and our pilot refused to take off even though other planes were. ( We could hear them)
His calculations meant he could get us up but should anything go wrong at the point of lift off , he could not be sure we could stop.
So we sat there until the snow depth on the runways was reduced and he felt happy.
Quite the right call in my opinion.
