OLHZN-17 was the seventeenth high altitude weather balloon flight for Overlook Horizon High Altitude Balloons. This flight launched on June 24, 2019 at 11:37:41am EDT (15:37:41 UTC) from the Rochester, NY area. This flight debuted our new recovery cut-down system that was placed on board the flight and made ready and available to automatically cut the payload free if it became entangled in an obstruction (i.e. a really tall tree) upon landing.
