An attorney for the Academy Award-winning composer says that Horner is missing after a small plane registered in his name crashed in Southern California, killing the pilot.
According to reports, the single-engine plane crashed at around 9:30 a.m. Monday in the Los Padres National Forest, which is about 60 miles north of Santa Barbara.
"We haven't heard from James," lawyer Jay Cooper told KNBC-LA. "We don't know where he was headed...He flies a lot and is an experienced pilot."
Horner, 61, won two Oscars in 1998, Best Original Dramatic Score for Titanic and Best Original Song (with Will Jennings) for writing the film's instant-classic theme, "My Heart Will Go On."
"What a shocker," presenter Madonna giggled before handing over the original song Oscar to Horner and Jennings 17 years ago.
The artist's vast body of work also includes the scores for Glory, The Rocketeer, Braveheart, Legends of the Fall, Apollo 13, The Amazing Spider-Man and Avatar. He's a 10-time Oscar nominee, his most recent nomination coming for his original score for 2009's Avatar.
Cooper said that Horner owns five aircraft, including two helicopters.
The crash of the S312 Tucano also sparked a 1-acre brush fire, according to Los Angeles' CBS 2 News. The circumstances surrounding the crash are under investigation by the Federal Aviation Administration and the National Transportation Safety Board.
