Nascar cars don't exceed 200 mph- WELL within any camera's ability to take a crisp, unblurred photo. Those photographers are probably doing it for dramatic effect. This jet is moving at about 1100 fps (750 mph) - tough to freeze the action.
I agree... which is why I'm curious as to how you can pan fast enough, and accurately enough, to freeze the plane. (Also I note that in almost al of the other shots--the ones linked by glatt for example--both the plane and the accompanying scenery are--this effect is not present.)

I'm not saying it was 'shopped.. I'm legitimately asking, as a pretty green photographer, how it was accomplished.

Practice. Follow it in from far away (when you have to move less) pivot at the waist for smoothness (I just know someone's going to jump on that). Use a pro camera like the Cannon EOS 1D Mark III- fire off 10 frames per second.

Looks like the photographer is farther away. That's my guess. Otherwise he'd have pulled in tighter on the jet. I'm going to go out on a limb here and say he's maxed out his zoom. That would put him so far away he only needs to pan very slowly.
Or, when the plane is come toward or going away from the photographer, he doesn't need to pan at all- as in the close-up ones of takeoff and approach.

...off to work.
Later Gents.

Yeah that would help a little too haha. Oh my poor 2.5 frames per second

Right on Adam. There are a great number of things to consider when working with telephoto and looking at a telephoto image.

Another thing to consider SteveDallas is that a general rule of thumb for telephoto lenses is that you need a minimum shutter speed of whatever mm length you are "zoomed" to in order to create a sharp, non blurry image of something stationary to begin with, let alone freeze action. Cameras can only have so high of a shutter speed (unique to each camera, example my Nikon D50 DSLR has a high of 1/4000th of a second, my previous Panasonic FZ7 had a high of 1/2000th). So if the photographer was far away using say a 300mm lens, which is a somewhat common telephoto length, then he/she needed to use a minimum shutter speed of 1/300th of a second in order to first have a non blurry image of anything, and then go up from there in order to attempt to freeze the plane in motion. Combine panning with that and the jet moving ridiculously fast and it becomes hell of hard to get a sharp image.

The reason why some of the other images do not appear to be as shaky is because the photographer was not using such a long telephoto length (closer to the action and/or simply cropped the original photo) and thus has much more control of the image.

Imagine trying to follow a moving object with your eyes from 200 meters, and then the same object moving at the same speed at 10 meters and you'll get what I'm saying. Just like how when you are driving your car, the grass is all blurred whizzing by but the mountains in the distance are nice and clear.
