Radiosonde X4738153 recovered by TSI

53 days old eco-model from Helsinki University. Found the balloon (not burst, leaked?) on the ground, string up to trees. String snapped but found soon the sonde on the ground and got probably most of the string collected. Nice, I will now have the biggest May 1st balloon in the neighborhood :D
