Doctor: DJ AM and Travis Barker Will Recover

After surviving a jet crash that left four others dead in South Carolina, Travis Barker and DJ AM (real name Adam Goldestein) are expected to fully recover from the second- and third-degree burns they sustained in the incident on Saturday, says Dr. Fred Mullins, executive director at the Joseph Still Burn Center in Augusta, Ga., according to CNN.com.

Travis, who was burned on his torso and lower body, and DJ AM, who suffered burns on his arm and head, could still be hospitalized for weeks after the crash. Investigators are now looking into whether a blown tire could have contributed to the crash. 

TMZ also reports that a source  says DJ AM is "ambulatory and in good spirits."

The four dead have been identified as pilot Sarah Lemmon, 31, of Anaheim Hills, Calif., co-pilot James Bland, 52, of Carlsbad, Calif., Travis's assistant, Chris Baker, 29, of Studio City, Calif., and Charles Still, 25, of L.A., Calif. 

Air traffic controllers reportedly  "saw sparks coming from the runway" before the crash.  Investigators don't know if that was from the aircraft or its engines.
