OLHZN-13 was the thirteenth high altitude weather balloon flight for Overlook Horizon High Altitude Balloons. This flight launched on May 28, 2018 at 3:21pm EDT (19:21 UTC) and carried 3 onboard Lightdow LD4000 Cameras along with our new micro-payload that was introduced on OLHZN-10. This flight also utilized our new on-board landing prediction software that was introduced on OLHZN-12 and allows the payload to provide predictions of its own landing site ahead of time and relay that information to the ground crew (and anyone following our live flight map) to get our chase team as close as possible to the landing site as the balloon descended.
