Approx 1 jump in 20000 ends in Death?

Recommended Posts

I recently received products that I ordered from a mail order supplier of gear, and there was a warranty/warning flyer included that stated that 1 jump in every 20,000 result in death. That seems a little high of an occurance rate to me. Does this make sense to anybody? They state in a footnote that the information came from U.S.P.A. reports.
...FUN FOR ALL!

The DZO in Hazelton, PA (Don Kellner) has over 34,000 logged jumps. I was just talking on the phone with him the other day so I know he isnt dead B|

Statistics need to be viewed in a very general sense, not taken literally.
I was under the impression, though, that the number was considerably higher than 20,000. I only have 57 jumps so far so I'm not worried ;)

Doesn't Bill Dause over at Lodi have over 34,000 jumps, too?

I don't think those two got the 1 in 20,000 memo yet.B| Let's hope it stays lost in the mail.

According to rather reliable statistics, 29 people died last year, out of 3.2 million skydives. That's about 1 in every 102,000 according to my oft-faulty math.



Well, the math is a little faulty . . . 3,200,000/29=110344.8 . . . but worse than that is the assumption the numbers are accurate to begin with. They are estimates at best.

Hmmmm, that would mean that every time we jump out of an airplane, we are taking a statistical risk of 0.00005 or 5^-5 chance of death. That is an interesting numerical value and seems like it would be a ligitimate guess if nothing else. I wonder how accurate USPA's data is regarding number of jumps made at any given time. I'm sure they would have the most accurate data out there but I would imagine there would probably be a small amount of error associated with it just because I don't think there is any way to know the exact number of jumps made at any given time.

I'd bet that overall though, that kind of error would probably be pretty insignificant in the big picture.

well here is a comforting thought,

If a canopy fails to deploy every 750 jumps (statistically) then a double mal happens every
750 x 750 = 562500 jumps, therefore only one in five of the (statistical jumps ) jumps inwhich you die will be a double mal,

Doesnt that make you feel better, Cos the other 4 are all your or someone elses fault,

From when I started reading this site there has been lots of talk of statistics, how about we get all get together and start up a REAL statistical database?

According to dz.com there are 617 dz's in the world at least one person from each dropzone must know about this site and read it?!

Lets do something about it rather than moan when we are misquoted by outside organisations.

Can a page be added to each dz on the dz.com dz database?

A page that lists what? Number of jumps at the DZ? Some places keep those numbers away from their compitition since then everyone else will know how business was for them and can organize their business accourdingly.

I think the last issue of Parachutist showd Bill Dause with a grand or two less based on the number of diamond wing award things.

Like Bill Dause has google-diamond wings and Don Kellner has googleplex-diamond wings.
These guys have been running neck and neck since I made my first jump back in 1989 but I believe that Don has the upper hand. He holds the Guinness record and has for as long as I've known him.

I doubt that the stats for a reserve failing are as high as those for a main failing, given the difference in the way the two are packed.

Plus, you have a mal on your main, unless you have balls of steel you're gonna chop it. If you have a mal on your reserve you're likely to make the best of a bad situation...:S And not necessarily die.

But if my assumption is wrong I'm gonna start paying my rigger £4 instead of £35 a pop...

That is a good idea, the problem is who is going to cooperate and who is not? Who is going to keep accurate records and who is not? Who is going to report their jump numbers and who is not? How about the people who do one tandem, go home and never register with USPA?

It would not be too hard to keep track of jump numbers made to a fairly accurate level. If each and every DZ in the US (or worldwide depending on how large you want your population to be) kept a year to date log record of every jump made at that DZ and number of fatalities, number of incidents, etc. it could be done. But then what about all of the DZs who aren't USPA affiliated? There are a lot of what ifs and it would require regulation and the cooperation of every skydiver who ever makes at least one jump ;)

I think alot of you are missing what this is saying. It is not saying that YOU PERSONALLY can go 20,000 jumps without dying, it is saying that every 20,000 jumps all across the us or world or whatever, someone dies. In otherwords, there could have been 19,999 safe jumps and that next jump you make will statistically increase your odds of dying.

I dont buy into it, but thats what it is saying.

No- that is not at all what it means.
