C_A,

Yurek clearly stated that the photograph was taken at a distance of 250 meters, but on the day he slung those lead glandes he was 500 meters from the viaduct.  Read for yourself:

Does it not say clearly that he slung from a distance of 500 meters, and that the photograph of the viaduct was taken from a distance of 250 meters?


(Later)
On the other hand ... the above rant is not quite to the point of your post.  Ahem.  Maybe I need to address what you said, and not what I thought you said when I committed the sin that I just accused you of (to wit, not reading the whole thing) ...


(Still later)
On the other other hand, you cannot compare a photograph of a geographic feature, with a real (different) geographic feature, and judge distance.  Did you take a photograph of your field, to compare to Yurek's photograph of the viaduct?  Then you might compare.  But again, it would depend on the lens used.

Photographers know all about this, especially those that work for advertising agencies.  I have seen photographs of the interior of some automobiles, for instance, where it looks like I would not be able to reach my arm out far enough to touch the person in the passenger seat.  They want me to think that the car has a large interior.  They choose angle and lens and lighting to get that impression across, in a way that bypasses the thinking part of my brain (if it's in working order, that is).

What it comes down to, I guess, is that I am am willing to have FAITH in Yurek's ability and willingness to measure a distance, and you want PROOF which you will get only by going to Poland and measuring it yourself.


As for the search engine here ... you have a good point.  I have learned how to use it, in spite of its deficiencies, but it does take a lot of work to find things.  But it is the tool we have.

er... how did Yurek measure the distance???  I have measuring tools and wonder if it was with any like or similar in function to mine.   I can't afford a surveyor's GPS but I know their accuracy is a less than an inch (25mm... actually 25.4 if we are talking about setting records)...  I have a 100 meter chain (well it's actually made of fiberglass) and a transit to maintain alignment.

Visually the Big Horn mountains to the east of us appear to be no more than 5-10 miles away...   on some days... on others they look closer to 50 miles away.... 5-10 is shy and fifty is farther than they actually are... as a game hunter who sights in firearms (and has out to 1000 yards) I know estimating distances can be pretty difficult and some have even resorted to the new dopler laser radar range finders (Abram's tanks know the distance to a spotted target to within less than an inch and do use the laser radar... er... so I have heard).  I have an older optical one and have more recently been coveting the newer laser ones...   If you use GPS and walk a line away from your spot in direction 180 degrees from each other and note the exact moment and place your number changes, you can measure back to the spot using those references and they are supposed to be within about one foot.... so I've been told.  I have a friend who works for an engineering firm who does these things and last time I saw him in the field, he was waering the GPS... maybe I can get him to help...???

I'd still like some suggestions for setting up a range and verifying distances...  otherwise can you imagine the jawing that could take place with LH, Tint, C_A and TechStuf throwing against each other... there will have to be NO possibility of anything distance being subjective

I'll bring some slightly smaller pumpkins, just in case.

It's because of the Chemtrails. rotfl

Yep my only point left unanswerd is was it measured in which case yep perspective is probably to blame or was it guestimated in which case I'd say it's probably over guestimated, very easy to do and no insult intended (gods you people are sensitive to non-intended-non-insults :-).

Okay what I'm talking about is:

Mine that I paced to 240 yards - those are mature oaks and birches - not tiny bushes.

See what I mean - even given the perspective issue, the tree sizes on yureks just don't look that far away. Given the 2 pics I'd say yureks aqueduct was around 150m - but if it was actually measured, then it's just a trick of perspective.

In this pic - from where I'm standing to the furthest line of trees is about 400 - 450 yards -  this based on the fact that neither field is quite as wide as the one I measured.

It is a lot further than most people realise.

And my only query is did yurek measure or guestimate ?
That's it, no character impugned or honour tarnished.

And lol yep I can see kilting as a form of recogniton - now that makes sense to my own sense of eccentricity :-)

Ok, I really see that you have a problem (no insult intended).

The following ridlle might help you understand "the perspective issue".

Here are the two pictures of the same tree, the both have been taken from the same direction.

Pic. 2

Please, tell me, on which picture the woods are closer to the camera and what the distances are (or maybe they are the same?). It wouldn't be a big problem for you, as you can estimate distances from pictures more accurately then somebody is able do it being outdoors.

Anyway, the picture I have put here, just because I wanted to illustrate the place where I was slinging that time. This one was taken in another time and was not intended as an evidence of something. It is just a picture of the slinging place and me slinging stones, just for fun. So looks like your above speculations drive to nowhere. Or if you just are trying to question my ability of measuring of stright secions, you should know that my educational background is sufficient to do it well.

That time I used to use a bicyle counter, which I callibrated and veryfied with a measure tape and later with a scale at a runway. In this way I was able to measure distances with average deviation +/- 10 metres at the 500 m. During the try the all glades were lost, hence it was not possible to measure their ranges exactly. Then the goal was to find whether some of the glandes exeeded the measured 500 m line deeply enough to have confidence that the real distance of 500 m got really exeeded. On the picture you can see the white ruined building. The 500 m line was located just past it. There was an obserwer hidden behind the walls. Although thare was no chanse to see landing glandes, but they could be easy heard when were hiting the peblly ground or something around. During the mentioned try the observer was absolutly sure that one of the projectiles hit the viaduct. I was very excited but not convinced in 100%.

That is why I repeated the attempt some time later. It was executed more carefully. My son hiiden behind the abandoned ruin was noting exact times and localizations of knocks. Just after each throw I was noting briefly the direction, exact time, angle and power of each shot. When I finished I went to him (all the time he was waiting hidden until he heard my voice). After comparing the both notes I had no doubts that I really did it. He described every heard sound very well.

Consider too, I'm not mentionig how far the furthest glandes landed behind the LINE. Although I had my own estimations, never didn't publish them, [b]just because they were only estimations[/b], at a guess, or rather at the ears of my soon. I only want to say that some distance excesses were big enough to compensate the bicycle counter deviation. The only thing were said on the forum, that I was able to exceed the distance of 500 metres.

In order to stop any furher speculations I would like to say that none of my attempts was official and there are no evidences. I don't care about them, as I did it just for me, in order to verify if I had a chanse break David Engvall's reccord using a classic sling and projectiles. I was inspired to do it by some members of the forum. They were ecouraging me and giving their support. There was a lot discussions on the GWR that time. So there wasn't a reason to not share the results then. Consider that by the nice time I have not been bragging about the results around. I mentioned about them, only when I was asked by someone.

So please, believe or not, but don't try to make a fool or a mythomaniac of me just due to that reason :)

Jurek

Okay... I like the wheel with counter... We marked the locations for most of the mileposts in the State of Montana in 1966 with such a device.  We had error factors we were constantly using but the accuracy was a thousandth of a mile (5.28 feet). 
Don't take any offense Yurek... some of us only believe in data and NEVER in a conclusion.  My personal thanks for sharing that data.
