I am currently crewing for a glider in the same comp that this incident happened in. It was a tough day for everyone, especially after hearing the news. This accident is pilot error, as you should never get that close to a glider in the air. It’s likely either the pilot who crashed or the one who landed was looking at their instruments in a thermal and wasn't paying attention to his surroundings. He was very respected in the scottish gliding community and all scottish pilots remaining in the comp have picked up their trailers and left. We know as much as the media do on the state of the pilot, but the fact he didn't use his parachute before crashing means it’s likely he didn't survive. The weather is definitely playing a factor in these crashes but the last few days have been exceptional cross country flying conditions.
