A private jet carrying six people crashed late Friday night at the Columbia Metropolitan Airport in South Carolina, killing four and injuring performers Travis Barker and his performing partner DJ-AM.

The privately owned aircraft never got off the runway, crashing at the end near S.C. 302 around 11:55 p.m., said airport spokesperson Lynne Douglas. The airport is currently closed to all arrivals and departures.

Officials said as the plane readied for takeoff just before midnight Friday, air traffic controllers saw sparks. The plane ran off the runway, landed on an embankment on a four-lane road and burst into flames, said Debbie Hersman of the National Transportation Safety Board.

Barker and DJ-AM, whose real name is Adam Goldstein, were taken to the Joseph M. Still Burn Center in Augusta, Ga., hospital spokeswoman Beth Frits said. Both were departing after performing at the T-Mobile Boulevard event in Five Points, near the University of South Carolina, earlier in the day.

Barker and DJ-AM were admitted early Saturday morning. “They’re both listed in critical but stable condition,â€Â said Frits.

Frits said Barker and Goldstein had their “injuries assessedâ€Â at a Columbia, S.C., hospital before Goldstein was airlifted to the burn center.

Barker arrived “by ground transportation,â€Â Frits said.

Lexington County Coroner Harry Harman said three men and a woman were killed, including the pilot.

Three of the victims have been identified as the pilot Sarah Lemmon, 31, of Anaheim Hills, Ca., and co-pilot James Bland, 52, of Carlsbad, Chris Baker, 29, of Studio City, Ca., Lexington County Coroner Harry Harman said.

Chris Baker is the personal assistant to Travis Barker of blink-182, Harmon said.

Charles Still, 25, of Riverside, Calif., who is a security guard for Travis Barker, has been identified as a fourth victim of the crash. The airport will remain closed indefinitely until the NTSB “gives us permission to clean up the runway,â€Â airport director Mike Flack said.

Investigators are looking at tire marks and other physical evidence in their quest to determine what caused the crash. As part of the routine investigation, they̢۪re also checking to see what the pilot and co-pilot had been doing for the past 72 hours.

“We haven’t ruled anything out at this point,” Hersman said.

The four who were killed all died at the scene, Flack said. Pieces of the plane broke off; the fuselage caught fire, he said.

“We’ve never had anything like this,â€Â Flack said. The weather was cool, dry and clear at the time, he said.

The fatal crash is the second at the airport in less than two years. On Jan. 4, 2007, three Columbia-area men were killed when their single-engine Cessna crashed in woods in foggy weather during approach to the airport.
