Wichita UFO
Well, I'm glad I started this thread. Thanks all for a very good discussion. "...I think we all agree that this UFO is for all practical purposes, an IFO..."

I agree with Ivan's last post - and if nothing else, this has been a good exercise in photo interpretation.
Btw, I played with some models of an E-3 in flight simulator - if I can find one with a better paint scheme for this, I'll post it, but I found a few interesting things: -It is possible for under-wing engine nacelles to disappear given the correct viewing aspect (1:00, low). -Wintip mounted antennas (static dissipators?) can appear like downard curved wintips from some angles. -This isn't an E-3 - the configuration of the tail and "dish" are not right. They are too close and the dish is too low. Could be a different, similar configuration awacs, though. |

If this enhanced image gets approved it's darker but the contrast is clearer and the flares are clearer making them look like lights. Not sure what is going on but I read the file as just over a meg but when I upload it it says 36.5k so it may not pass.

nottheone, that image appears excellent! how did you enhanced the image? |

Here's what I interpret in nottheone's touch up...

But your extrapolated interpretation doesn'r hold water if you now compare it back to the original image (instead of nottheone's touched up version). |

Why do you think it does not "hold water" compare to the original image? |

notheone's image blurs many edges, making it easier to interpolate straightish lines where there were none (eg. 1] port wing, trailing edge and 2] nose taper). If you now put your interprertation next to the original, you'll see that the trailing wing edge is not continuous and the nose taper is completely different. Those are just a few examples. |

2 ideas...
Flying mole cricket with a jet strapped to it's back.... Coming at us and to the right... lol http://paynomind.com/media/1/2009020...%20cricket.jpg Or going away from us and to the right a B2 with a jet strapped to it's back. Kinda like this, only the nose angled up a little more, and pointed away from us a little more: http://www.fas.org/nuke/guide/usa/bomber/b2bombs.jpg As the first flyby happens watch the angle of it.... http://www.metacafe.com/watch/775852...by_at_airshow/ Not saying it was a B2, but maybe something similarly shaped with a jet of some sort on the back. |

I'm not quite following the points you raised, however, the fact that it is missing a vertical tail fin seems to definitively rule out the perspective I suggested.
After taking another look at the original image, I realized that it's absolutely impossible for this to be a plane of any kind at all. Based on the focus of the tree in comparison to the object it's clear that the object is significantly nearer to the camera than the tree, and that it's size is therefore quite small. Then taking another look at the image, I'm almost positive that this is a picture of a bird. There is a downward curve in the front characteristic of a beak, and a flat tail in the back with no vertical fin indicative of a bird's tail feathers, and the odd structure over the torso is easily explained by motion blur between the flapping wings. The bright spots aren't lights, they are reflections. Bird feathers can be quite reflective, especially when wet.

The circle of confusion in the image for the tree branches is ~4.5 pixels, and for the object it is ~10.5 pixels. The fact that these two numbers are different means that the objects are at different distances. If this were an airplane, one would assume that the distance of the object was greater than the tree. However, that's not optically possible. As the distance of an object approaches infinity the change in size of the focus of confusion approaches zero, as illustrated by this animation: ![]() From wikipedia, we can write the circle of confusion radius c as c = A*abs(S2 - S1)/S2*f/(S1-f) But in the same image, all of these are constants except for S2 (distance of the object), so for the purposes of the discussion it can be simplified to c = k abs(S2-S1)/S2 where S2 is the distance of the object being imaged. The thing about this function is that c asymptotically converges quite rapidly to S1 as a function of S2. In other words, objects more distant than S1 have a very limited effect on increasing the size of confusion. That is why, for example, other very distant objects like the con trails still appear in focus in this image. If S2 is closer than S1, the size of circle of confusion increases very rapidly. This is the only way to explain the very large factor of 2.33 in the relative size of focus of confusion, and is conclusive proof that it is not an aircraft, but rather a small object in the foreground of the tree. ![]() Most people should not need to resort to math to come to this conclusion, though, because our brains are naturally capable of interpreting this type of information. This is why when you look at the whole image (not just the cropped part around the bird) it is quite obvious that the fuzzy object is close to the view, and a rough estimate of scale can even be perceived... |

Having gone to college for photography I am aware of depth of field geometry. But you are too sure of yourself (especially ironic as you flip-flop your sureness from post-to-post).
1] If you dismiss the observer's account you might as well dismiss everything. A picture means virtually nothing without the details of the account. In this case, we are actually lucky to have a witness account. One thing the witness account does is rule out that the object is small and nearby. Without the account we would have to consider that as a possibility. 2] As mentioned before, there are other reasons than differing distance why the two objects are not necessarily blurred the same way. Interestingly, you have already explicitly mentioned one of them in your own 'bird' account. Suddenly, now that you're sure it's a bird and not a plane, you seem to give it no consideration at all. While you raise good points worth addressing, don't shoot yourself in the foot by making any claim "absolutely". Discussing anything with someone who is convinced of their rightness is a futile exercise. |

Awesome.
The original link seems to have rotted but I've found an image of it that's 3Megs. And if that ones rots, I've saved it to my HD. http://kwch.images.worldnow.com/imag...o_original.jpg |
