On Friday March 18 we launched a latex high altitude helium filled balloon from Troy NY and recovered it in Weston MA, a flight of 225 kilometers (139 miles). The balloon reached an altitude of greater than 70,000 feet, but unfortunately we lost contact and do not know the maximum altitude achieved, we estimated it at between 80,000 and 90,000 feet. Although the goal of the flight was to fly the Tufts sonic anemometer – we were unsuccessful this time but we will try again! It was a good dry run to understand the radio and tracking equipment. All FAA and FCC regulations were followed, and a NOTAM was filed.
