700K Flight from Poland to Holland

After the Junior Pre-World Contest in Leszno, Poland ended on Sunday 12 August, the Dutch competitors (Jan Willem van Doorn, Stefan Telkamp, Sander Luimes en Nick Hanenkamp) decided to fly back home to Holland on Monday 13 August. They almost made it: Their flight ended at Stadtlohn airfield which is located virtually on the border between Holland and Germany. They covered a distance of almost 700 km, an epic flight! See http://www.onlinecontest.org/olc-2.0/gliding/flightinfo.html?dsId=2686332 for flight details.
