OSM is a very fast developing project in Europe, Great Britain is leading, in the Netherlands and Germany there are nice activities, all surrounding countries need some more volunteers. No big activity in the US. So for Europe it seems to be good source for FlightGear data in the medium. This was my special interest that made me buy a Garmin 12 GPS some months ago at eBay and make some contributions to the project. JOSM is a really nice product to edit your data loggings before uploading. Especially the background Landsat 7 option is very nice to digitize data you otherwise never would have gotten. Only, as Martin reported, the cooperation between the group and interested FG developers is a little difficult. But solutions can be found, I am sure. I am a big fan of the OSM idea.
