Day cancelled for all classes

At 16:00 the day was cancelled for the remaining two classes. Everyone is tired from sitting around at the grid all day but relieved.

In the evening was the official opening of the OSTIV congress.
OSTIV stands for Organisation Scientifique et Technique Internationale du Vol a Voile or International Scientific and Technical Soaring Organisation. The OSTIV congress is always parallel to the World Gliding Championships. The organization studies areas such as glider design, soaring meteorology, flight training and safety including human factors. Met some old friends from my days in aerospace design.
