Your Tornado pic was taken at around midday, with a high sun => bad light, so it will come out very contrasty. As it looks right now, your second edit looks still oversharpened, too high contrast and oversaturated. It's not a bad picture at all, but it's a difficult one to edit.

In workshops especially designed for aircraft photography people were talking about USM with a much higher factor and radius.
Not necessary to start an argument, but I didn't say anything about the quantity (=factor) of USM
to apply, only about the quality (=radius). The factor of USM
will always depend on each picture, but I can tell you that on my pictures (and I usually pick out the sharpest one out of a very sharp lens like the 70-200L) I use one pass of 500% and 0.2, and then maybe if really necessary a second one of 100% and 0.2.
In your case, since the picture is already very contrasty, and it shows a lot of small details, it will probably stand much less sharpening.
Hope it helps and we can see more of your Luftwaffe pictures!
