Sad day. It was the L-39 registered as ZU-HIT. She and her sister ship (then registered as ZU-RUN exported to the UK from SA in 2008) had a complete overhaul of frame and avionics in 2005 (if I remember correctly). The overhaul took almost a full year to complete. She was a good looking plane and when I saw her last (earlier this year at the Rand airport airshow) she looked in great condition. Hope investigators can find and gather enough information to come to a firm conclusion.
Condolences to the family and friends.
