"Glider death

Man, 53, killed while trying to pass aircraft under bridge

A 53-year-old man was killed on Saturday when the glider he had been
operating plunged into the Polyfytos Lake near Kozani. According to
police, the 53-year-old mismanaged a maneuver under a bridge crossing
the lake and fell into the water. It is unclear whether he was killed
by the impact or whether he drowned."
