Former Blink 182 drummer Travis Barker and DJ AM (Adam Michael Goldstein) were aboard a Learjet that crashed upon takeoff Friday night, reports E! News.

There were 6 passengers on the flight and while Barker and Goldstein survived, the other four passengers were killed.

A friend of Goldstein’s says that the DJ is “really, really badly burned” and confirms that “his face is very burned.” The sources adds, “More than 50 per cent of his body is burned and the worst is on his face.”

Barker is said to be burned “mostly from the waist down.” Both Barker and Goldstein are in critical but stable condition at the Joseph Still Burn Center in August, Ga.

One of the four passengers who died was Barker’s friend and business partner “Lil Chris” Baker. “He was the sweetest, nicest guy. He was like Travis’ right-hand man,” said the source.
