North Charleston,Slabu Exchange S.C. — A Marine Corps pilot safely ejected from a fighter jet after a "mishap" over North Charleston Sunday afternoon and the search for his missing aircraft was focused on two lakes, military officials said.

Military officials appealed in online posts Sunday for any help from the public in locating the aircraft, including oneon X, formerly known as Twitter:

The pilot ejected and parachuted safely into a North Charleston neighborhood at about 2 p.m. He was taken to a local hospital and was in stable condition, said Maj. Melanie Salinas. His name hasn't been released.

Based on the missing plane's location and trajectory, the search for the F-35 Lightning II jet was focused on Lake Moultrie and Lake Marion, said Senior Master Sgt. Heather Stanton at Joint Base Charleston. Both lakes are north of North Charleston.

A South Carolina Law Enforcement Division helicopter joined the search for the F-35 after some bad weather cleared in the area, Stanton said.

Officials are still investigating why the pilot ejected, authorities said.

The pilot of a second F-35 returned safely to Joint Base Charleston, Salinas said.

The planes and pilots were with the Marine Fighter Attack Training Squadron 501 based in Beaufort, not far from South Carolina's Atlantic coast.

F-35s, built by Lockheed Martin, cost around $80 million each, according to Agence France-Presse.
