Radiosonde W1150717 recovered by TSI
This 150 days old was easy find, because telemetry was received until timer reached zero. Meaning last known location is the exact landing spot. But reaching it was tricky. First route ended into farmhouse (thanks, Google Maps!). Second route was a private road. Finally, third route led "close" enough (sweaty kilometer thru bushes). Sonde and balloon on the ground, most of the string was left in treetops (not reachable with my 6m pole).
