The organisation of the World Hang Gliding Championships are sad
to announce the death of Japanese pilot Masakazu Kobayashi. It seems like
Masakazu Kobayashi hit a cliff. The organisers present their deepest sympathy to
his family and friends.

For the organisation, Jean-Louis Debiée

It was quite a difficult day with a strong inversion. I've heard
of other incidents on this day in Annecy. I'll report if and when I get
confirmation.
