Ok I need some understanding here. I have studied your editing guide and i am having some stupid issues that maybe you can help figure out. When getting ready to apply USM i bust out the magic wand and click on the sky. Some of the times the marching ants make a boarder around the AC. But most of the time I click on the sky and the marching Ants are all over the place. How do i fix that? I am beating my head on the desk as we speak. The problem I am having is why I am limiting myself to the pics I take.
Also Is it correct to apply USM after you resize or should I apply to before i re size.... Thanks for your support

If you click the sky with the magic wand, it does just that, it selects the sky, or rather all pixels that it thinks is the same as the one you clicked. But, you don't want to sharpen the sky, so you need to inverse the selection (Select->Inverse).
I don't use the magic wand, it's a blunt tool. Use the Quick Selection Tool, it's easier to pick exactly what you want by using different brush sizes, magic wand picks what it thinks you want. Hold shift to enlarge the selected area, and Alt to decrease it.

+1 for the Quick Selection Tool
The Magic Wand works to some extend when you have a completely blue sky and the aircraft has no blue in it. But if you have a picture of an aircraft on the ground, you have almost no luck using the Wand.

Just a related tip that I know you can do in GIMP, and assume in Photoshop, too - in the GIMP there's a setting with the magic wand called threshhold (I think it's the same as what sovietjet called tolerance) that lets you change the value difference between the pixel you click on and those that will be selected.
It's still a very imperfect method, but this does give you a little more control.
Also, I prefer to do my sharpening on a copied layer and use the selection I make to create a layer mask rather than working directly within a selection.
