According to CNN, Former Blink-182 drummer Travis Barker and disc jockey Adam "DJ AM" Goldstein were in critical condition with extensive burns Saturday after a jet crash the night before that killed four people, authorities said.

Lexington County Coroner Harry O. Harman said all the dead were Californians. He identified them as pilot Sarah Lemmon, 31, of Anaheim Hills; co-pilot James Bland, 52, of Carlsbad; Chris Baker, 29, of Studio City; and Charles Still, 25, of Los Angeles.

The Learjet 60 crashed on takeoff at the Columbia Metropolitan Airport at 11:53 p.m. Friday.

Beth Frits, spokeswoman at the Joseph Still Burn Center, in Augusta, Georgia, said Barker and Goldstein arrived at the hospital early Saturday. She said both men had "extensive burns."

Eye witness, William Owens was driving down a highway next to the airport when he said he saw a fireball go across the road. He told local TV station WIS News 10:

"I didn't know what I had seen — it was maybe 800 feet in front of me, but as I approached it closer though I made out a fire. By then I was able to see the tail of the jet and I recognized it as a jet," Owens said.

Owens then described what he saw as he tried to make it to the wreckage.

"It's in flames and the fuel is running across the road and I had to cross the fuel to get to the two guys that seemed to have been dumped on the highway," Owens said.

Owens said the two men were running around and stripping down to extinguish themselves. He then asked the men if there was anyone else on board the plane and they said four more were with them.

"We turned to the jet to try and see if there was anything we could do, but immediately, there was nothing anyone could do," Owens said.

Barker and Goldstein had played at a huge free outdoor concert in Columbia's Five Points district on Friday night.

Thoughts and prayers to the families and a speedy recovery for the injured.

The medical director of the Georgia burn center where the two are being treated after their escape from a fiery plane crash around midnight Friday said Sunday morning that both critically injured men are expected to make full recoveries.

Dr. Fred Mullins of the Joseph M. Still Burn Center at Doctors' Hospital in Augusta said at a press conference that former Blink 182 drummer Barker, 32, and DJ Am (real name: Adam Goldstein), 35, are being treated for second- and third-degree burns.

Mullins says recovery from such burns can take as long as a year but says that the men suffered no other injuries, adding: "Since both Barker and Goldstein are in overall good health and didn't suffer from any other crash-related complications, a full recovery is expected." [PEOPLE]
