Ouch. Some really bad days for British gliding. Given how small the Scottish gliding community is, we will probably all know the folk involved.
'GLIDERSEEKER' - I don't know how experienced you are but sometimes even with the best of look out going on and electronic aids too, threats are not spotted as we'd hope they should be, even with everyone's heads swivelling. Blind spots. shifting turn patterns etc. Busy, strong thermals on a comp day are part of the inevaitable hazard, sadly.
That Dunstable accident , being on take-off sounds like a high probablity of it being a winch launch issue; we do seem to be having too many of these just now - why?
