The brief moments of trying to catch flight turned horribly bad in just seconds. "The truck took a turn ... the turn caused a little bit of slack in the line ... and when the slack came out of the line it yanked the glider and caused the glider to stall and nose dive into the ground," Corbin Moorhead said.
This came next supposedly through a police report:
The pair of hang gliders were in the air when the truck pulling the glider turned around abruptly, police said. The driver of the truck thought the tether had been released, as is usually done by the person in the glider.
The glider came crashing down because the tether had not been released, police said.
This one came after the family returned home:
Family members said everything was going smoothly until they noticed there was too much slack on the tether connecting the glider to the truck. They said the driver sped up to fix the problem and that's when things went wrong.
"As the driver increased in speed, it yanked the glider and the glider plummeted to the ground headfirst and me, my brother, my mother and my grandmother watched it as it plummeted to the ground and we raced to the crash site," said the victim's brother.
Nothing is absolutely clear. The family, the police and the reporters all very likely had never seen or knew anything about what was supposed to take place in order to accomplish a safe flight.
Ignoring the "truck took a turn" (brother's statement) or "turned around abruptly" (police report) because they don't detail the actual sequence of events, this quote seems most telling to me:
Family members said everything was going smoothly until they noticed there was too much slack on the tether connecting the glider to the truck. They said the driver sped up to fix the problem and that's when things went wrong.
I keep seeing a lack of resistance on the drum as the instigation of the problem. The glider blew off the launch just fine at around 30 mph or so giving them an instant 40 or 50 ft. of altitude. A short flight could have been safely accomplished without any rope attached at this point. The pilot could just pull in and set up his glide to a landing.
But there was a rope attached, pulling somewhat, and sagging enough that neophytes could easily recognize this as a problem.
With very few split seconds available for the pilot to assess the situation, he likely (instinctively) pushed out and entered a mush while the driver sped up/dialed up more resistance on the drum.
The rest of the scenario played out with timing of the rope quickly going tight and a glider that was mushed out, nose high and likely crooked.
The picture above is the result. Being connected (tethered) and rapid increase of tension, at that point, was the biggest detriment to pilot recovery and control of the glider.
A reliable, instantaneous release at the right time, without removing hands from the control bar, IMO, would have been the only hope to recover from that situation.
After decades of towing, this type of release isn't readily available and not commonly used. What was Harrison using? We don't know but I will bet that his release could have only been activated by removing one hand from the control bar, as that is the industry standard.
The development and discussion of reliable, hands on the bar releases has been systematically suppressed for many years by those now concerned about a crash like this on their ability to fly/profit from this sport. It's all documented in Tad Earicksons' archive at http://www.kitestrings.org/
Kelly Harrisons' towing experience likely didn't give him the insight he needed to disconnect when it was needed anyway. More experienced pilots likely would have the same outcome.
But even for those that might attempt an early release, taking a hand off the control bar in a developing lock out negates the benefit of a release anyway. And that is if the release actually worked as it's supposed to work.
Of course this is all speculation, but what's next? Cover it up and keep on doing things the same way?
Based on past practice, that would be my guess..
