I think we're working on the same lines here. I've written a searchable database containing every test & explosion from authoritative sources.
It will output the results of any search as KML or CSV.
If anyone wants to help ensure its accurate and up to date, I can give you update rights.
http://nukes.tjworld.orgI was wondering about some additions, but not sure how much use people will make of it.
1. Store links to online photos and documents related to specfic explosions
2. Allow users to add their own comments and reports as "commentary"
Other ideas welcome.
