This year a German guy did 110 km in a Hols der Teufel - a bit more than a Grashopper but not a lot! And a Dutch guy did a 40 minute soaring flight on a Grasshopper - with no instruments!
Now those were flights!
I did once meet a lad who on an excellent soaring day had just failed to do his 50k .......in a Discus. Doh!
I always reckon that if people in their £80 K glass gliders have 40 times as much fun as I do in my £2K Skylark 4 then they must be seriously happy pilots!
So have fun out there, and keep the Oly's etc flying.
