People should check out the Earth Explorer site from the USGS: https://earthexplorer.usgs.gov/ https://earthexplorer.usgs.gov/ It has a huge number of high-resolution aerial photos for large swaths of the country going back to the 1930s, and not just urban areas. The interface is really clunky but once you get the hang of it you can find an enormous amount of data. I couldn't find mention of it but I'm sure the OP site obtained their photos from there.
