A Marine Corps F-35 fighter jet belonging to the US Army has varnished.

According to US army, the fighter jet went missing somewhere over South Carolina on Sunday, after the pilot of the jet ejected because of a “mishap.”

Two military installations in South Carolina—Joint Base Charleston and Marine Corps Air Station Beaufort—are working together to locate the missing fighter jet, an F-35B Lightning II, using its last-known position, which officials believe is located near Lake Moultrie and Lake Marion, just north of Joint Base Charleston.

The pilot of the fighter jet was taken to an area medical center and is in stable condition after safely ejected from the aircraft Sunday night, Joint Base Charleston said in a Facebook post Sunday evening.

The F-35 was left in autopilot mode when the pilot ejected from the jet, Jeremy Huggins, a spokesperson for Joint Base Charleston, told NBC News in a story Monday, signaling there’s a possibility the aircraft could still be airborne somewhere.

In a tweet, Joint Base Charleston asked members of the public to call the base if they have “any information that may help our recovery teams locate the F-35.”
