Video of the Chinese ship Haixun 01 appeared to show an extra pinger on board. That pinger would just need to get wet for it to start transmitting — noise that could then get picked up by the ship’s search crews, said Anish Patel, president of pinger maker Dukane Seacom. The company supplies black-box beacons for Malaysia Airlines.

“It takes the slightest bit of moisture for that water-activated switch to automatically fire up,” Patel said.

He added that it’s “not best practice” during a search to keep another pinging device where you’re listening.

你觉得那个Anish Patel在造谣吗？！还是这个记者在造谣？！
