A woman who went for her first hang glider trip in tandem with a pilot had plunged one thousand feet to her death in a fatal accident on Saturday afternoon on Woodside Mountain in British Columbia, Canada.

Lenami Godinez, 27, tried hang gliding after her boyfriend paid for her lessons as an anniversary gift. He was supposed to fly next had tragedy not struck. He was video-recording her flight, but had stopped taping when she fell, Daily Mail reported.

The hang gliding instructor sensed something was wrong the moment Miss Godinez's tandem hang glider launched from the mountain, the Canadian Press reported.

Hang gliding is an extreme air sport, in which a pilot maneuvers a light and unmotorized foot-launchable aircraft. The pilot is secured in a harness, and directs movement by shifting body weight.

Miss Godinez had slipped out of her harness, then she tried desperately to cling to her instructor - first by grabbing his legs, and then his feet, until his shoes had loosened, making her lose grip and fall to her horrible death. She was found seven hours after her fatal drop, and one of her instructor's shoes was later discovered 60ft away from her body.

The pilot had tried his best to hang onto her, said Jason Warner, a hang glide safety expert who spoke to the pilot minutes after the accident, according to Canadian press.

Authorities have not confirmed whether it was pilot error or equipment failure that had ultimately caused the tragedy.

Miss Godinez, who was originally from Mexico, was an administrator at the provincial Ministry of Environment.

Sgt Mark Pelz, of the Royal Canadian Mounted Police, told local news Kent Harrison Search and Rescue received an emergency call at about 12.15pm after the incident.

The pilot was reportedly in a state of shock after the tragedy.
