A US Navy plane carrying 11 passengers crashed Wednesday while en route to the the USS Ronald Reagan.

Japan, which is helping in the search and rescue efforts, said eight on board the C-2 “Greyhound” aircraft have been found. They were transferred to the USS Ronald Reagan for evaluation, and “are in good condition at this time,” US Navy’s 7th Fleet said in the below statement:

Search and rescue operations recovered eight personnel following a C2-A Greyhound aircraft crash southeast of Okinawa at approximately 3:23 p.m. today.

All personnel were transferred to USS Ronald Reagan (CVN 76) for medical evaluation and are in good condition at this time.

Search and rescue efforts for three personnel continue with U.S. Navy and Japan Maritime Self-Defense Force (JMSDF) ships and aircraft on scene.    

The names of the crew and passengers are being withheld pending next of kin notification.  

At approximately 2:45 p.m. Japan Standard Time, Nov. 22, 2017, the C2-A aircraft with 11 crew and passengers onboard crashed into the ocean approximately 500 nautical miles southeast of Okinawa. The aircraft was conducting a routine transport flight carrying passengers and cargo from Marine Corps Air Station Iwakuni to USS Ronald Reagan (CVN 76).  Reagan is operating in the Philippine Sea as part of an exercise with JMSDF.   

The C2-A is assigned to the “Providers” of Fleet Logistics Support Squadron Three Zero, Detachment Five, forward deployed in NAF Atsugi, Japan. Detachment Five’s mission includes the transport of high-priority cargo, mail, duty passengers and Distinguished Visitors between USS Ronald Reagan (CVN 76) and shore bases throughout the Western Pacific and Southeast Asia theaters.   

The incident will be investigated. 

The cause of the crash was not immediately clear, however, Japanese Minister of Defence Itsunori Onodera told reporters that the US Navy informed him that engine trouble might have caused the crash, Reuters reported.
