While on a vacation trip to South Dakota, I took this picture. I did not see the object until I downloaded to my computer. The photo was taken from Rim Road in the Bad Lands Park. The direction is generally south. The time was 11:11 AM, on 5/18/2008. The full frame has been reduced for email use, but otherwise has no processing.

The crop is at full definition with no compression over the original. The camera was hand held, but as you can see there is no blurring due to camera movement on the scenery. I also had the image stabilization on. A second picture was taken nine seconds later and the object was not there.

The lens setting was 17 mm. This is the equivalent of 28 mm on a 35 mm camera. The object must be either large or close to the camera. It appears to have some motion blurring which means it is going very fast as the shutter speed of 1/200 will stop any aircraft not very close. As you know the speed of the image on the sensor plane, not the object speed, is what counts.
