The pilot of an F-35 jet safely ejected, but the world's most advanced fighter jet is now missing.
The U.S. military seeks assistance in locating the presumed crashed aircraft.
On Sunday, near Charleston, South Carolina, a pilot from Marine Fighter Attack Training Squadron 501 ejected from an F-35B Lightning II jet.
The pilot was ejected safely, but soon after, emergency teams began looking for the jet.
The reason for the pilot's aircraft abandonment is unclear. Supposedly, it was a "mishap" that is under investigation.
The base is also encouraging the public to contact them with any information or sightings that might help recover the plane.
Joint Base Charleston said, "Based on the jet's last-known position and in coordination with the FAA, we are focusing our attention north of JB Charleston, around Lake Moultrie and Lake Marion."
The jet takes part in airshow demonstrations and comes from a squadron whose mission involves training F-35 pilots and support crews.
This latest incident occurred around five years after another Marine Corps F-35B crash in South Carolina in 2018.
