A closed 600 km circuit flown on an Archaeopteryx.

On the 27.05.2020 Franz Pacheiner completes a really big flight. After an
aerotowed launch he flew for 10 hours and 40 minutes to an altitude up to 4200
meters. From his home turf in southern Austria, his circuit covered some places
in Austria, Slovenia and Italy as well before landing back at home. The
Online-Contest shows 601 kilometers by OLC-classic rules and by OLC-PHG rules a
flat triangle of 576 km.

Awesome Franz!
