A. People are not all the same as each other.
B. People are not even the same as themselves.
When the wing is stalled we all start accelerating down at 32 feet per second squared. And until the wing starts flying again all men are created - and uncreated - equal.
I'm sure you can't be the only two people in hang gliding with some brains. Am I right or not?

I thought I should post this since the phone keeps ringing with friends worried about Jim and wanting information. Here is what I know. Yes, the Jim in the article is OUR Jim, Jim Rooney. It was a tandem hang gliding accident, and it involved a power line. I have no more information about the accident itself. The passenger apparently was burned and is hospitalized, but is not seriously injured. Jim sustained a brain injury. He was and is heavily sedated, which means the doctors don't know and can't test for how serious the brain injury is. He is in critical but stable condition.
There are AT LEAST three of us. These guys are doctors so who's to argue?
You yourself told me about moments when "the light went on" and you had an insight about towing that you didn't understand before.
Yeah, I've had zillions of lightbulb moments in hang gliding. But if I had gone with sailplaning I imagine that I wouldn't have had any. The information would've all been in all the books that everyone had been using for the previous fifty years and I wouldn't have had to unlearn all the crap with which I'd been programmed by all the whack jobs who felt that they needed to reinvent aviation from scratch for hang gliding 'cause we use somewhat different control system.
So we're all changing and learning.
Yeah?
Learning is measured by changes in behavior.
If you went to platform or aero tow operation twenty years ago what would you see different from today?
I'm thinking gliders, harnesses, and instruments and other electronics.
Winches, tugs, three-string, Wallaby, Bailey releases, flimsy weak links, cheap, dangerous bridles, people scared of taking their hands off the basetube to go for the actuator, people trying to get the flare timing just right and breaking downtubes and arms when they don't... all the same. The stuff that the tow operators, tug drivers, and instructors control NEVER gets any better 'cause their "thick as a brick" "moments" are measured in geological divisions of time.
The reason that less people are launching from rooftops with feathers glued to their sleeves is that more people have seen the consequences of that action.
Not the greatest example to use in a discussion concerning hang gliding.
http://www.youtube.com/watch?v=2mX2HNwVr9gAt least the people test flying the feathers always had the feathers when they gave it a shot.
Our collective knowledge is growing...
In this area always about how to be better disciplined about the procedures you use so that you can assume you're hooked in when you're on the ramp.
...and our ability to disseminate information is growing as well.
Measure the curve on a pin from a twenty year old Bailey release, compare it to the curve on the one you buy from Wallaby this weekend, and tell me how it matters.
It was a failed experiment exactly because a small group (who felt THEY knew better) seized power.
"THEY" *DID" know better. They seized power. Just like Admiral King said they would.
It was because we failed to have a democracy.
And you failed to have a democracy because you failed to have checks and balances. So you got yet another iteration of Uncle Joe.
Maybe you didn't follow it closely...
I didn't follow it at all - Jack was involved. Oklahoma, trailer park... big surprise.
He killed the communication channels that would've allowed a better outcome.
For whom?
But here's the hope.
You're doing a lot better job maintaining it than I am.
So when we have proof of a result (like the failure of the SGAA), then we can use that proof with teachable people and with non-teachable people in their teachable moments.
Within about a half an hour of Donnell Hewett coming up with his absolutely lunatic strategy to use a light weak link to:
infallibly and automatically release the glider from tow whenever the tow line tension exceeds the limit for safe operation
there were scrap bins, emergency rooms, and cemeteries overflowing with indisputable proof that the idea was pure unadulterated crap.

I witnessed the one at Lookout. It was pretty ugly. Low angle of attack, too much speed and flew off the cart like a rocket until the weak link broke, she stalled and it turned back towards the ground. Since then, Lookout went through the trouble of "sizing" their carts to help avoid that. They even made a handy plywood gauge you could hold up to your keel and verify the AOA was good.
I witnessed the one at Dare County Regional. It was pretty ugly. Taking off in her Cessna 152, low angle of attack, too much speed. A Tundra Swan flew in front of her. She pulled up like a rocket until the propeller disintegrated. Then she stalled and it turned back towards the ground. Since then, Dare County went through the trouble of thinning out the swan population to help avoid that. They even hired a couple of local hunters to patrol the runway ends during the heaviest operating hours.
You don't let Donnell, Malcolm, Matt, Steve, Davis, or Rooney define a propeller, its function, or its specs and you don't let the goddam pilot decide what is and isn't acceptable for his plane. You tell the sonuvabitch that it's gonna meet these standards or he's not gonna fly - whether he's teachable or not. And that's been working just fine for general aviation - and the 0.0001 percent of pilots who have the desire, capability, and resources to roll their own.
The scientific method can't function in an environment where some facts are allowed and others are prohibited.

Common sense tells us that the last thing we want to do in an emergency situation is give up control of the glider in order to terminate the tow.
If your system requires you to take your hand off the control bar to actuate the release it is not suitable.
With as many facts as anybody wanted to put out there (both of those clips are from the magazine) screaming in people's faces for over thirty years how much difference has common sense made? But diver drivers are suddenly gonna start embracing the scientific method to lay the foundations of a new organization based upon reason and fairness that'll move things in a positive direction?
I repeat...
Humans are stupid herd animals that are perfectly OK with stampeding over the cliff to the south in response to the sound of a falling tree to the north just as long as everybody else is stampeding in the same direction.
And you know what's gonna happen to an individual who understands what's going on and tries to stand between the herd and the cliff?
Herd animals value two things when they select their leaders - skull thickness and testicles size. Davis, Jack, Rooney, Tracy... Starting to make sense now?
And ya know the ONLY significant aspect of hang gliding that doesn't totally suck?
My training is in engineering, and engineering is built on the strong foundation of science. But science itself is built on the strong foundation of the scientific method.
The gliders themselves I trust. And that's 'cause individuals in the engineering layer of the gene pool use their heads for thinking - rather rather than bashing through people trying to turn the herd to a less deleterious direction - and have more energy to do it 'cause they don't get exhausted from having to haul their testicles around in wheelbarrows all day long.
Backup suspension DOES NOT make gliders safer - it makes them A LOT more dangerous.

Ya know why we have backup suspensions on gliders?
Mike Meier - 2005/08/~18
It shouldn't matter whether the backup is in front or behind, because it should be longer than the main such that it is always slack in flight. An argument could be made that IF the main hang loop broke, you'd rather have the backup in front because the most likely scenario in which you'd break the main would be pulling high positive G's, and in that case you'd rather have the pitch trim become more nose down than become more nose up, but on a Falcon 2 that's not really a consideration. As far as where the backup "usually" goes, we usually put it behind the main because that's usually where there's room for it. If the main is properly maintained, and periodically replaced, it is never going to fail anyway, so the backup is sort of pointless. Years ago we didn't even put backup hang loops on our gliders (there's no other component on your glider that is backed up, and there are plenty of other components that are more likely to fail, and where the failure would be just as serious), but for some reason the whole backup hang loop thing is a big psychological need for most pilots.
We need to keep the goddam stupid pilots as far away from design and policy issues as we possibly can, get a scientific method based rule of law in place, and cut hands and balls off of the divers who think that their votes and opinions should influence the conduct of aviation. The air is no place for democracy or freedom of speech 'cause Mother Nature doesn't give a rat's a** about either.
