Saildrone Explorer SD 1078 is an unmanned wave-rider that dove into the heart of Hurricane Fiona in the Atlantic Ocean this week. It sent back some wild video as it battled 50-foot (15-meter) waves and winds in excess of 100 mph (160 km/h).

These little Saildrones are increasingly sailing around the world’s oceans collecting valuable data. Below is SD 1078’s eerie video from inside Hurricane Fiona.
