Death of skydiver in Lévis under investigation

Lévis police and the coroner's office are investigating the death of an experience skydiver on Sunday

Marc Gilbert, 47, had accomplished over 3,000 jumps before plunging to his death at a training centre.

Gilbert was reportedly practicing a high-velocity manoeuvre called "swooping." The technique calls for fast turns when reaching more than 300 meters in altitude to experience a faster landing. Swooping often involves speeds of around 100 kilometres an hour.

The victim had practiced swooping about a dozen times.

"The parachute was opened. We know it was not a traditional jump," said Éric Laliberté, spokesperson for the police.

Patrick Coupal, the training centre's co-owner, says Gilbert may have miscalculated his altitude as he approached the ground.

This is the sixth fatal skydiving incident in the province in the past four years, and the third in the greater Quebec City area.
