Incredible new video inside a hurricane is being called a world-first by experts.

A drone captured the video from inside the eye of a powerful category 4 hurricane, barreling across the Atlantic.

The National Oceanic and Atmospheric Administration partnered with Saildrone Incorporated to send the hi-tech, unmanned vessel into the path of Hurricane Sam.

It passed through nearly 50-foot waves and 120 mph winds.

Scientists say the data being gathered can be used to better improve forecast models.
