I don't want to speculate, but maybe he was referring to an unhooked tandem passenger/student falling to their death.

JOHN KELLY HARRISON Obituary
Harrison, John Kelly, age 56, passed away Friday March 28, 2015 in a tragic hang-gliding accident in Jean, Nevada. He was born February 22, 1959 to Lorrin "Whitey" and Cecelia (Yorba) Harrison. Kelly lived a life full of adventure. Growing up in Capo Beach, he excelled at surfing, paddling outriggers, diving, and all watersports. Later in life he got involved in hang-gliding, karate, white-water rafting, skiing, sailing, fishing, etc. He was a white-water guide on the Colorado River, ski patrol, EMT, hang-gliding instructor, kayak adventure guide, airplane pilot, an avid poker player and an exceptional human being. Kelly was also a successful business man, owner of Plenty Pupule Kayaks in Kona and Kauai, where he also hosted the Pelagic Pursuit kayak fishing tournaments. Carefree and spontaneous is how he lived his life, which made him fun to be around and his infectious smile brought happiness and fun to all that knew him. Kelly's greatest joy was getting people out of their comfort zones and challenging their spirit of adventure. Kelly is survived by his daughter, Danielle Obinger; sisters, Ginger Grey, Marian Tompkins, Jennifer Van Swae; brother, Lorrin Harrison Jr.; and 2 granddaughters. John Kelly Harrison's Memorial Service will be held at Doheny State Beach on Sunday April 12th at 2:00pm. All friends are welcome, please join our celebration of his life.
