NTSB Searches for Downed Boeing Cargo Plane Off Hawaii

The U.S. National Transportation Safety Board said it would scan the ocean floor on Monday to locate a Boeing 737-200 cargo plane that sank off Hawaii last week after the two-member crew made an emergency water landing.

Investigators plan to use sonar technology to search for the decades-old plane and recover cockpit voice and flight data recorders, the NTSB said in a statement.

"That information will be used to determine how and when the recorders could be recovered and then how and if the airplane will be salvaged," the agency said.

The agency has recovered and examined a small amount of floating debris from the flight, it said.

A Boeing spokesperson said the company’s technical team was helping the NTSB investigation.
