A court document alleges the pilot involved in the fatal hang gliding accident near Agassiz, B.C. Saturday tried to destroy evidence by swallowing a memory card.

William Johnathan Orders, 50, of Burnaby, was arrested shortly after landing his glider in a field at the base of Mount Woodside after his tandem passenger plunged to her death. Lenami Godinez-Avila, 27, became detached from the glider moments after takeoff and fell 300 metres.

Orders was charged with obstructing justice on Monday and police say other charges could follow.

Paragliding pilot Nicole McLearn witnessed the tragedy and says Orders filmed the incident.

"I was aware that video was being taken because the pilot in command showed me the camera ahead of time saying, ‘this is my new camera, this is how it works,'" McLearn told CTV News.

Police did ask for the video, but would not say if it was successfully recovered.

Alex Raymont, a paraglider who participated in the search for Godinez-Avila's body, hopes police will have the chance to view the recording.

"It will make the accident investigation a lot better. You might see if they attached her properly; the whole sequence of events leading to the launch," he said.

McLearn also watched Orders set up his Glider and says he missed a crucial safety check.

"I was there pretty much for the entire time that they showed up until the time they launched and I did not see a hang check performed," she said.

A hang check is executed by having a pilot and passenger hang from a stationary glider to make sure they are properly attached.

"It's probably a little more awkward with a tandem, but yeah, it should be done," Raymont said.

Criminology professor Robert Gordon from Simon Fraser University says criminal negligence is another possible charge Orders could face.

"You're criminally negligent if you're doing anything or you're admitting or failing to do something that is your duty to do, and in doing that you're showing wanton or reckless disregard for the lives or safety of another person," he said.
