Balloon Flight B-15, 4 October 2013

Almost no changes from B-14 in tracker features and operation.

Tracker hardware is the same as B-10 and B-12.

Balloon entered saturated clouds at 8000m and seem to have picked up enough icing to cause it to descend to the Finnish-Russian border. Finnish radioamateurs organised extensive search expedition to find the balloon but sadly were not able to locate it. It could have drifted a long way at a few hundred meters over ground level from the last known position.
