I apologise for not informing you in advance of the point of the article. The scientific studies we have to use as a baseline tell us that eyewitness observations and testimony, _in general_, vary in accuracy from 70% accurate to 45% accurate. Of course there will be exceptions, there will be some examples that are 100% inaccurate and some that are 100% inaccurate, and we would expect the range of total accuracy/inaccuracy to be something like 30% to 55%. We're talking about population studies here, studies done _in general_, and it is inapplicable to attempt to extend _in general_ results to _specific_ events and expect to find an exact match. In your example what percentage level of inaccuracy is needed to tentatively establish the _basic_ observations? Four people saw the same sized object, same lights, no sound, same maneuvering. That they all agree on those observations suggests that (assuming the testimony was properly taken) those observations are accurate and representative of what was there to be observed. What other observations were made? (We don't know.) What accuracy comparisons exist for them? (We don't know.) Would it matter if the other observations were largely inaccurate? (Most likely not.) -- Thanks, take care. John. (             ) [ ] [ firstname.lastname@example.org ] [ ] (             ) Page from the website of: CohenUFO.org
