Three men who went missing after leaving from Polowat Atoll, Micronesia, to go fishing were rescued by the U.S. Coast Guard on Tuesday, after a U.S. Navy plane saw their plea for «help,» which was spelled out on the sand using palm tree fronds.

The Coast Guard said in a press release that the three men, all in their 40s, left from Polowat Atoll on March 30 to go fishing near Pikelot Atoll, a 31-acre deserted island roughly 100 miles from where they left in a 20-foot skiff with an outboard motor.

The three men, who were not identified, were reportedly experienced in navigating the waters, though when they went missing, family members became concerned.

Joint Rescue Sub-Center (JRSC) Guam started coordinating search and rescue operations after the trio was reported missing.
