Tonight on AC360 Randi Kaye visits the Woods Hole Oceanographic Institution to get a first hand look at REMUS. It stands for Remote Environmental Monitoring UnitS, and it was used to help locate the wreckage of Air France Flight 447. It was also used to detect mines in the Persian Gulf and leaks in underwater tunnels. The Navy says it can do the work of up to 16 divers, and go places where they cannot.
Check out a behind the scenes look at Randi's report.
