U.S. Coast Guard crews detain personnel aboard a self-propelled semi-submersible captured in the Eastern Pacific off the coast of Central America, Oct. 21. A U.S. Customs and Border Protection Maritime Patrol Aircraft detected the SPSS. The 378-foot U.S. Coast Guard Cutter Jarvis, on patrol in the region, intercepted the vessel. Jarvis' crew found that vessel was loaded with narcotics, seized the SPSS, and detained the four crew members.
