According to TMZ, a plane registered to film composer James Horner—who scored blockbusters like Apollo 13 and Titanic—crashed in southern California Monday morning, killing its pilot. No others were on board.

The pilot has not yet been identified, but long-time attorney Jay Cooper tells The Hollywood Reporter that no one has talked to Horner since.

“We know it’s his plane, and we know we haven’t heard from him,” Cooper told the magazine. “I’ve checked with the other reps.”

“He loved flying,” added Cooper. “That’s all I can say.”

CBS Los Angeles reports that it is not clear if mechanical failure brought down the aircraft and the crash is currently being investigated.
