A military helicopter took off from the USS Abraham Lincoln and later crashed into the sea leading to search-and-rescue operations off the coast of San Diego, the US Navy's Pacific Fleet said on Tuesday.
"An MH-60S helicopter embarked aboard USS Abraham Lincoln (CVN 72) crashed into the sea while conducting routine flight operations approximately 60 nautical miles off the coast of San Diego at 4:30 p.m. PST, Aug. 31," the Pacific Fleet said in a message on Twitter.
"Search and rescue operations are ongoing with multiple Coast Guard and Navy air and surface assets," the message said.
