Has anyone considered having "before" and "after"
images available.
Actually, that's how this is supposed to work. They show you an image taken since Fossett disappeared, and also provide you with Google Map coordinates.
If you see an anomaly in the recent photo you're shown, you can paste the coordinates into Google Map and compare, looking for differences.
You then report whether you did or didn't see something you think an expert should review. Multiple people are presented the same image to help normalize what's reported.
