Maritime expert on possible explanations for power loss, collision

Captain Jim Staples is a master mariner who spent nearly 40 years at sea, including 23 years as a captain on all types of vessels, including cargo ships. Now, he does consultant and investigative work for agencies ranging from the Department of Justice, to the NYPD's Counterterrorism Maritime Division. He says losing power on a ship like the Dali happens more often than you hear about. It just doesn't usually end in a catastrophe. "I've had things like this happen to me," Capt. Staples said.
