This might become an interesting thing, so I post it in both the General and Flightsim forum.

the search engine is programmed by Google. the thing searches only flightsim-related web-sites. They are currently building the database and network of weblinks, so it is in a pretty early stage. the small flags indicate that it also will become international in language soon.
Maybe worth to keep an eye on it.
