By Jerry W. ParrishMIKE MOSS SAYS: Jerry, Your yard served as a landing pad for a Vaisala Radiosonde unit that was probably launched from the National Weather Service upper air station in Greensboro. The system is attached to a helium balloon that carries it to an altitude of about 90-100,000 feet before the balloon expands (due to decreasing outside air pressure) to a point that it bursts, and the package parachutes to the ground.
