Earthtreks about 2 weeks ago:

A climber began climbing an auto belay route forgetting to hook in and got to the top forget he wasnt hooked in and let go. Fell broke his back both legs and an arm.

I believe thats the whole story no one really knows how the person forgot to hook in...

I never forget to flush the toliet.

maybe I'm just slow or something, but how does someone forget to clip into an autobelay? [ . . ]really, I'm curious what was going through the two posters' minds as they climbed. You forgot to clip the locking biner? so, you just basically climbed up without clipping anything to yourself?

so it's not like, say, with a knot, where you could pull a "Lynn Hill" and not rethread or something.

Maybe you need to read Lynn Hill's book.

....
"Okay, climbing," I said to Russ, using the simple verbal signal all
climbers use to tell their partner they are setting off.
But this time the system had a glitch in it: pilot error. I had poked the
rope into the loop in my harness, but, distracted by the actions of fetching
my rock shoes and chatting with the japanese girl, I had not tied the knot.
The end of the rope hung at my waist, hidden underneat my jacket, like a
ticking time bomb. Neither I nor anyone else at the cliff noticed my
potentially fatal mistake.
....
At any point in the 72 feet of Buffet Froid's steep face, the rope could
have slipped out of my harness and snaked down the cliff through the
carabiners to land in a pile on the ground.
...
But the rope did not detach from my harness and Russ did not get the
opportunity to come scampering up the rock to rescue me. Had that happened,
we would have engaged in one of those caring-yet-chiding husband-wife tiffs
that end in laughter.
....
And then I reached the end of the climb, about 72 feet above the ground....
To descent safely, I only had to lean back and Russ would hold me, carefully
letting the rope slide through his belay device... I leaned back, expecting
the rope to hold me. Instead, I felt the rush of air against my cheek.
.....
Climbers at the cliff and in the valley that day described a "bloodcurdling
scream" that echoed off the walls. My scream -an involuntary shout of
horror- was even heard by Pierre, the mayor of Buoux, who sat in the library
of his house half a mile away. Looking toward the source of the scream,
climbers on neighboring routes saw a figure free-falling down the cliff,
carving an outward arc through the sky. All told, I covered the 72 feet in
less than two seconds.
....
It is not true that in a fall one sees one's life flash before one's eyes.
There is not enough time for even a single formed thought. But survival
instincts are wired on a faster pathway that any other mental process, and
when I saw the approaching tree I knew instinctively that my best chance to
live was to land in it. If it could be said that I aimed myself at any
landing zone, it was toward that short, stunted green oak tree.
Speeding toward it, I tucked my body into a ball, blasted through its
brances, then my left buttock slammed into a lattice of tree roots sprawling
on the ground. The impact jarred the senses out of me.
Jennifer Cole, an american climber at the cliff that day, said that when I
hit I bounced three feet into the air like a rubber ball, then I released my
tuck with the flail of arms and smacked onto the ground, face first into the
limey dirt.

Maybe the guy was just stupid and didnt know what the hell he was doing. Did he have a harness?

If you are talking about the fall at Earthtreks 2 weeks ago, I saw it happen. The climber fell, got up and walked around immediately after while moaning in agony/pain. ET Employees jumped to his aid and he left in an ambulance. I heard he sustained no major injuries despite falling a solid 35 feet. I do not know where you got this broken leg, back thing from, but if it is the incident I WITNESSED he surely did not do that much damage to himself.

I heard from a friend of a guy whose sister's boyfriend was there that the guy topped out the climb, and the auto-belay device severed the rope..... and chopped off his hand.

you will eventually forget. in your girlfriends house. while her parents are visiting. murph's rules, you know.
