I totally agree. If any airline allows its aircraft to get airborne in appalling weather without workable alternates for the primary destination and with weather at the point of origin on a PROB40 to deteriorate below minima by the time of any likely return, I'd expect them to have the book thrown at them - Czech, Irish or French. It just so happens that in this case, it was a Czech airline which happened to think it was worth a go.
Sure. But the virtual book had been thrown at them here long before this incident - mostly for reasons for which realistically Citywing was to blame.
