I was in Prievidza shortly before the WGC kicked off.
Sincerest condolences to family and friends of deceased pilot. I am sure this will affect everyone there very greatly, but I hope it can be of some comfort to know that our fellow aviator died doing what he loved.
As the WGC represent the best of the best of the countries represented, this tragedy is a lesson to us all that aviation carries risk to everyone, no matter how skilled. There but for the grace of God go I.

Our fellow aviator was Alexander Martynov from Russia. RIP.
