Dear All,

A modest contribution to be ignored/jeered at (delete as

Suppose the telephone pole is 15' high at 50' from the camera,
so subtending somewhere around 20 degrees, then the angular size
of the blurred object is order of 1-1.5 degree. (This sort of
rule-of-thumb calculation is relatively insensitive to
variations of a few feet/degrees/mph here and there. Exact
trigonometry could easily narrow down the range of possible
values.) Therefore if the object were (say) 30' from camera it
would be approx. 6" - 9" long. A 6" - 9" bird travelling normal
to the optical axis at a speed of 20 mph will travel 1/3 - 1/2
its own length in a shutter time of 1/125 sec and will show
significant lateral speed blurring. This is not inconsistent
with the photo.

On the other hand, if it was (say) a 50' saucer speed-blurred by
displacing 1/3 of its own length in 1/125 sec then it would be
about 3000' from the camera travelling at about 1300mph. This is
not inconsistent with the photo either.

>From the point of view of the photographer viewing the scene
through the camera the two scenarios are equivalent. He would be
no more or less likely to notice the saucer than a nearby bird.
But for a companion, presumably not looking through a camera
viewfinder, a 1300 mph 50' saucer flying by would be a very much
more noticeable object. Given that the photographer was not
alone, and that nobody noticed the saucer, the bird hypothesis
has to be considered the more likely.

As to whether the image looks like a bird, I think it does. Its
flight attitude would be tilted towards the camera, left wing
up, right wing down, travelling L to R, light-coloured upper
wing surfaces sunlit. The 'saucer' highlights are due to the
dihedral of the wings caught in a raised position between
