The REMUS Autonomous Underwater Vehicle (AUV), manufactured by Hydroid, Inc., works deep below the surface of the ocean to show what lies beneath. Boston television station Fox 25 spent the day with the Hydroid team on Cape Cod to learn how the REMUS works. Fox 25 also learned how the vehicles helped recover wreckage from Air France Flight 447, which broke up over the Atlantic Ocean. With great reporting from Mark Ockerbloom and professional editing, Fox 25 made this story sing.
