Historic NOAA-Saildrone mission did more than set records. It’s helping scientists improve hurricane forecasts

On September 30, 2021, a saildrone uncrewed surface vehicle made history by intercepting the eyewall of Hurricane Sam in the northwestern tropical Atlantic, recording a viral video of what it’s like to be tossed around by 100 mile-per-hour winds and 30-foot high waves.  

The Guinness Book of World Records later certified that a 126.4 mile-per-hour wind gust recorded by the bright orange 23-foot saildrone in the core of the Category 4 storm was a new world record for an uncrewed surface vehicle.
