Dan,
Regarding FLARM data, files were sent to FLARM for review, but the wreckage was found before the data was analyzed and the effort was then suspended. Efforts to use a portable PowerFlarm to help pinpoint the glider were unsuccessful due to the fact the glider's FLARM and transponder were, we believe, without power. We will have to wait until the investigation is complete to verify the power issue, but the only hits we received on the PowerFlarm, as we flew near the suspected crash area were (as best we can tell), transponders from the search aircraft...
Thx - Renny

The aircraft was found very close to locations indicated by SPOT and FLARM, even though there was only one SPOT fix in the general area. The wreckage was difficult to find because it consists of very small pieces and is on a slope. The initial search also only started in late afternoon a few hours before sunset. We do not know if more location data would have helped..

I'm interested in the comment about FLARM; did the search use the procedure described in "FLARM® as an additional tool when searching a missing aircraft" on the flarm.com website? If yes, I'm curious how close their last known position (LKP) was to the crash site. If no, I wonder if the .igc files of those flying could be sent as described, and the LKP determined.

There used to be a direct link on flarm.com to the document, now it's buried a bit (found it at http://flarm.com/french-gliding-fede...tegy-on-flarm/ ).

There is a lot of data in the flarm messages that might locate a downed friend more quickly, if used...
