Fair point, but the amount of blur would depend on the shutter speed.
1/100 would have a fair amount of blur, but 1/1000th would have a lot less blur.
For example, let's say the F/A-18 was flying at 300mph: At 1/100th of a second, the plane moves about 4.4ft. At 1/1000th, the plane moves .44 ft.
Now, someone smarter than I am could probably input these numbers into how blurry an image should be, based off how fast a person pans the camera, but I am not that smart. Someone even smarter could input telephoto length to calculate blur.
More info on the approx speeds to stop motion:
http://www.passingimage.com/clients/pc_ ... n_Blur.pdfAt 1/2000th, that 100mph race car moved .07 ft. At 1/1000th, the 70 mph car moved .10 ft. At 1/500, that 40 mph car moved .11 ft. To stop motion, and stop blur, therefore, you cannot have the object move more than an inch, it appears.
Take away; It all depends on the shutter speed, Cheeseman.
Now, if we could see EXIF data in the original image, we could approximate how fast the plane was going.
