Trump rules out foul play in Navy aircraft crashes, suggests bad fuel may have caused USS Nimitz helicopter and fighter jet incidents in South China Sea.

All personnel involved were safe, and the causes of the two crashes were under investigation, the U.S. Navy's Pacific Fleet said.

According to the U.S. Pacific Fleet, an MH-60R Sea Hawk helicopter that was assigned to the Helicopter Maritime Strike Squadron 73 "Battle Cats" crashed around 2:45 p.m. local time while "conducting routine operations." All three crew members were rescued, the Pacific Fleet said in an X post.

The two separate crashes occurred about 30 minutes apart and involved a helicopter and a fighter jet operating from the USS Nimitz.

All personnel were safe and in stable condition, after a Navy helicopter and a fighter jet both went down in the South China Sea, the U.S. Pacific Fleet said.

U. President Donald Trump began the final leg of his Asia trip in South Korea on Wednesday, optimistic about advancing an unresolved tariff deal with President Lee Jae Myung and striking a trade war truce with China's Xi Jinping.
