Thanks, I think I already got a great response! What can one really say about it anyway?
The wreckage has still not been located, but the weather at the time gives a strong hint as to what might have happened. Visibility was 6 - 7 km in mist, locally down to 3 km and 500 ft cloud base. I was flying in roughly the same area a few hours later (but we remained over the archipelago!), and although the weather had improved with 7 - 8 km vis all around and NSC, it was still very hard to make out the horizong when looking towards the sea. The radar recording shows the aircraft diving steeply into the water at high speed.
A more remarkable thing about this accident was that although the pilot did file a flightplan, it appears overdue action was not taken until three hours after its expected arrival time. There will be an internal investigation into that particular aspect. Since this was an ultralight the Swedish AIB will not investigate the accident itself...
