I went out in my yard this morning and saw this piece of orange plastic hanging in a tree. It's a parachute and had a long line leading up to the top of a holly tree in my yard. I got my step ladder out and pulled on the line, hoping the payload would come loose, but the line broke. The stub of the balloon is attached to the parachute, and the warning label was also attached. The radiosonde is about 30 feet up in the tree. I may try to get it down once the rain stops. Apparently the balloons are filled with hydrogen.
