I've used the program below and it works....though it's been a long time since I've used it.
"USAPhotoMaps downloads U.S.Geological Survey aerial photos / topos from <a href='http://terraserver-usa.com/' target='_blank'>http://terraserver-usa.com/</a> (available at no charge, courtesy of Microsoft) and creates a map from them."

An example of a map.....
Can be shown in topo form also....
