Now we are getting somewhere. Jason, kudos for the most accurate post.
As Mavi points out, the data is useless. We would need airtime hours, total hours, launches and landings, training level, etc to even begin to make sense of this.
I think Spork is referring to US fatality stats. The US has roughly equal numbers of PG and HG pilots. In that sample size, since January of 2007, 13 HG pilots have died and 12 PG pilots.
But so what? No one can objectively say that HGs are therefore more dangerous. And how does one even begin to make the case that PGs are therefore more hazardous? We don't know any relevant data beyond those ugly numbers.
Many here take the Fox News approach; don't let objectivity get in the way of a belief system. People will ultimately believe what they want.
Back to Mavi, the data is so incomplete that it is useless. Yet many still try to call one better or worse. Good luck. |

| Hi Guys and Gals, Big Guy here. I see this animosity between Paraglider pilots, and Hang Glider Pilots. I for one think that a lot of it is not rooted in solid ground. Hell, Paragliders want to fly just like us. It is true that Paraglider pilots have huge balls, bigger than I will have. And after all they _ALLOW_ us to be part of THEIR club. |

Only if you want to look at the fatalities relative to those things. Certainly they're useful, but you can also ask the simpler question - "how likely am I do die if I fly paragliders this year? How about hang gliders?"
It might be worth knowing how likely you are to die if you're a H4, P4, fly XC, do aero... but the broader question is still of interest.

Correct.

That's right - we don't know any relevant data beyond those numbers. But those numbers can be taken for exactly what they are - nothing more and nothing less.

I claim it's far from useless. I believe it tells us that neither one is inherently much more dangerous than the other. It's true it doesn't tell us whether it's pilot judgment, training, aircraft stability, speed, etc. that makes this so - but it's apparently so.
| Quote: |
| Yet many still try to call one better or worse. |
And I've never claimed either one is better or worse. Frankly, you'd have to have a lot more than safety statistics to do that. I fly both. |

I don't think that's quite accurate. Hang out at a paragliding launch sometime, or on a paragliding forum. You're not likely to hear about how hang gliders and the people that fly them are the scourge of the earth. In fact you're not likely to hear anyone mention hang gliders or hang glider pilots.
Then go hang out at Funston when a paraglider gets too close to the area they think is "their" airspace - or simply mention paragliding at one of their "safety meetings". Listen for the threats. Watch the locals running to get their torches and pitch-forks. Or just hang out on this site and see if you can't detect the hate. |

The thing that pisses me off is that this organization was founded by Standard pilots, people who flew Rogallo wings. Then these people showed up who fly these damn contraptions with battens and double-surface sails, prone harnesses instead of swing seats, and all manner of that-all. We let them into our organization, they took over, and the next thing you know, the Standard pilots are gone! Completely! We let in these people flying Comets and whatever, and the original hang gliders that started the whole movement have been pushed out completely. When's the last time you saw any Standard coverage in the mag, other than maybe a faded old picture with a caption like, "Remember this? Isn't it quaint?"?

It's hard to argue with a well reasoned position like that. Hey - you're missing Fox News. |

That's why I don't get the mag anymore. All the real hang glider photos and articles have been replaced with these damn blade-wings. It's all just far too offensive to my sensitive sensibilities. |

Here are the stats I find useful.
In a closed sample of roughly the same number of hg and pg pilots, there are roughly equal number of fatalities over five years. For those keeping score, Hgs are up by one.
And yet,
On the oz report and hg forum, there are countless rant threads about pg safety. On the pg forum, there are no threads about hg safety. None. Zero. But there are plenty about improving pg safety.
So who is in denial? |

It reminds me a bit of windsurfing and kitesurfing. Lots of windsurfers hated the new-fangled rigs and the people that rode them. Now kitesurfers outnumber windsurfers by a good margin (at least around here), and I've still never heard kitesurfers talking about windsurfers. It's just not even a topic. |

I think a flaw in this question is how the statistics for HG or PG deaths are calculated. Let's say you can somehow get a somewhat realistic number on how many HG pilots there are that fly in the US, or the world, in a given year. Then you find out how many deaths there are in that year, among all those pilots. You will then have a death/pilot statistic. The problem is that that's too simplistic of a statistic since it does not take into account all the variables of HG flight, such as pilot experience, equipment condition/quality, flight location, weather, etc., etc.
The odds of an H4 pilot with 15 years of experience dying in a given year, vs an overconfident H2 would be drastically smaller. I don't think the statistics have been broken down into such detail, have they? So, the basic deaths/flight, or deaths/pilot aren't that valuable, IMO.
I also think the death statistic is given a little too much focus as well. What about serious, life-altering injuries? Like the trend of serious back injuries for PG pilots, versus more limb injuries (I assume) for HG pilots? A death does not need to occur to for an activity to be considered dangerous. |

It might seem so, but a lot of HG deaths and serious injuries have involved experienced, H4 pilots.

I would love to get into PG: the ginormous convenience of the entire rig fitting into a big backpack, the comparatively (to HG) easier landings, and an easier time staying in thermals being among the things that interest me. Like I mentioned before in this thread, the one issue I cannot get past is how unpredictable wing collapse can be. There's something unsettling about an activity that has a somewhat common (unsure of how common), unpredictable/unavoidable component to it, which can kill you, or maim you, if you draw the short straw when it happens.
I just don't see how such a thing can be so easily dismissed. Perhaps it just doesn't happen as often as I think it does. The fact that it does happen seems inevitable, and it's a roll of the dice whether or not it happens at a bad elevation or not. |

Perhaps that can be attributed to overconfidence? Like trying to fly in adverse weather, because they feel they have the experience to handle it? Or perhaps during competitions, where people are pushing the envelope, being much riskier than they would on a recreational flight. It's not like a PG collapse where they were just out gliding over some hills, having a leisurely flight, and all of a sudden, without warning, they began to plummet towards the earth. |

Probably overconfidence and complacency in most cases. Dead is still dead, it doesn't matter if it's caused by flying way over your head or making piss poor decisions or flying a wing that is unsuited for the conditions. Most of those bad outcomes could have been easily avoided with some better judgement. That's true of most things _________________ Paul H

Again, you can always break the stats down to finer detail. That doesn't mean the gross number of deaths per participant per year is not a valuable stat. I agree of course that it may not be of interest to you.

I wouldn't be so sure about that. H4's are likely to be flying XC, towing, etc. Of course you can define "overconfident" however you like.
It might be that only children are much more likely to die flying HG than pilots that come from large families. We don't know. And it doesn't mean the basic stats of fatalities per year is useless - at least not to me.

I agree completely. I'm personally more concerned with serious injury than death.

I'd be very interested to see such stats. I don't know that to be true. Flying head first has it's own risks. |

I agree, but I was attempting to keep the trend of debating which was "more dangerous", if that can even be quantified, between PG and HG. I'm trying to focus on unavoidable, dangerous situations, when comparing the two sports. Going down a flight of stairs by itself isn't that dangerous; trying to walk down a flight of stairs on your hands is. Pretty easy to avoid that danger. |

I think there's a three part answer to this:
1) I suspect it doesn't happen as often as you imagine
2) Very seldom is a collapse a big deal (of course a big collapse would be at the wrong time)
3) Many PG pilots only fly coastal ridge lift. |
