About OLHZN-17 :: Searing

OLHZN-17 is the seventeenth planned high altitude weather balloon flight for Overlook Horizon High Altitude Balloons.  This flight is expected to launch in early June 2019 over the Canandaigua, NY area. This flight will debut our new recovery cut-down system that will be placed on board the flight and made ready and available to automatically cut the payload free if it becomes entangled in an obstruction (i.e. a really tall tree) upon landing.  This scenario has occurred many times to us in the past (OLHZN-5, OLHZN-7, OLHZN-9, OLHZN-11, OLHZN-13, OLHZN-15) and becomes a nightmare during recovery which can take hours to try to free a payload from an obstruction, especially if it’s high off the ground.  The new cut-down system will allow us to remotely trigger a cut-down procedure to hopefully free to payload from the obstruction.  We still hope the payload will not land in an obstruction, but we’ll be ready with an additional tool if it occurs.  Additionally, even if the payload lands in an open field, we’ll still be collecting valuable data on how the cut-down system, particularly the safeguarding mechanisms, operate throughout the flight.
