Searchers find debris near where Chilean Air Force plane disappeared

Debris believed to be from a military transport plane carrying 38 people that vanished days earlier en route to Antarctica has been discovered in the treacherous waters of Drake's Passage, Chile's Air Force said Wednesday. Air Force General Eduardo Mosqueira said the material was found floating roughly 19 miles from the place the C-130 Hercules last had radio contact two days earlier.

The debris will be analyzed to see if it corresponds to the missing plane, he said, adding that the process could take up to two days.

The C-130 Hercules took off Monday afternoon from a base in far-southern Chile on a regular maintenance flight for an Antarctic base. Radio contact was lost 70 minutes later.

The debris was spotted by a private plane assisting in the search, and officials said a Brazilian ship in the area equipped with instruments will next scan 10,499 feet underwater at the site. The discovery came as Chilean officials said they had expanded the search for the missing military plane, and will scan an area of roughly 70,000 square miles.

Mosqueira said the search area covered an area of about 250 by 280 miles, and that improved visibility was helping the crews of searchers using planes, satellites and vessels from Argentina, Brazil, Uruguay, Chile and the U.S.

The search area extends over Drake's Passage between the tip of South America and Antarctica. The plane was carrying 17 crew members and 21 passengers, three of them civilians.

Ed Coleman, a pilot and chair of the Safety Science Department at Embry-Riddle Aeronautical University in Prescott, Arizona, said rapidly changing weather in the Antarctic makes it a difficult place for pilots. Air masses converge there, driving storms with powerful wind gusts, while stirring the sea with swells 20 feet or bigger, he said. Flying becomes challenging, and a smooth sea landing is nearly impossible, he added.

"You can have a clear sky one minute, and in a short time later storms can be building up making it a challenge," he said. "That causes bigger swells and rougher air."

The inhospitable Antarctic is equally formidable to rescuers, who have to respond quickly to pull any survivors from the cold, rough waters, he added.
