Not a bad idea! I've taken a few shots recently from the air of some neat stuff on the ground. I don't think it will work on this site though:
1. The photos really wouldn't be aviation related. That essentially would change the nature of this site. People visit this site to look at airplanes and other aviation related subjects. Plently of other websites exist for people to display their nature, landscape, or whatever you want to call them photos.
2. It would be very difficult to establish guidelines for photos to be accepted. What would be the criteria to add photos? Would any photo be accepted? Even the bad ones? One could submit nothing but photo after photo of Iowa cornfields.
3. How would you track and be able to search through these photos in a database that's setup for commercial aviation?
I'm not trying to piss in your Wheaties, but it really wouldn't be feasible to add a new section dealing with air to ground photos. Don't get me wrong, I like to idea! I have quite a few photos of this nature that I'd love to add! I don't think it'd work on this site.
