There was a time when modern military aircraft pictures were all I used for wallpapers.
I had everything from Tornadoes and Ardvarks to A-4s and F-5s. F-16s and F-22s to Gripens and Rafales. And E-8s to Ospreys.
I have amassed a huge collection of photos over the years. Unfortunately, 98% of them are 1024, so they're not really useable any more.
