Three men stranded on an uninhabited Pacific island survived for more than a week and used palm fronds to spell out HELP on the beach – leading to rescue by Navy and Coast Guard aviators who spotted the sign from several thousand feet in the air.

They had embarked March 31 in a 20-foot boat with an outboard motor from Pulawat Atoll, a small island with about an estimated 1,000 inhabitants in the Federated States of Micronesia about 1,800 miles (3,000 kilometers) east of the Philippines.

The men were fishing when they hit a coral reef, putting a hole in the boat’s bottom and causing it to take on water, Lt. Keith Arnold said in a Coast Guard video.

A Coast Guard ship, the Oliver Henry, picked up the men Tuesday and took them back to the atoll where they had set out nine days earlier and 100 miles (160 kilometers) away, according to the statement.
