Karel_x,
Thank you and, as I said, I was surprised to read the Pravda article. Now that the report is out, confirming there was nothing wrong with the aircraft itself, best wishes to Sukhoi in putting this accident behind them. Btw, I have no bias for/against Sukhoi, Embraer or Bombardier; the competition between them can only make for better and safer airplanes. Hopefully this accident will make for safer demo piloting.
