Climbers try to reach jet's black box in Indonesia Associated Press Copyright 2012 Associated Press. All rights reserved. This material may not be published, broadcast, rewritten or redistributed. Updated 02:40 a.m., Monday, May 14, 2012 JAKARTA, Indonesia (AP) — Indonesian special forces traversed the sheer slope of a volcano Monday after spotting what appeared to be the flight data recorder of a new Russian-made passenger jet that crashed during a demonstration flight for potential buyers. Search teams say they spotted what is believed to be the combined voice-and-data recorder, also known as the "black box," peeking from the wreckage at the bottom of a 500-meter (1,500 -foot) ravine, said Tatang Kurniadi, who heads the National Transportation Safety Commission. A ground proximity warning system should have displayed positions and heights of the mountain and other obstructions on a screen in the cockpit, Indonesian aviation consultant Ruth Simatupang said, but it's possible that data about the terrain in that area had not been properly uploaded.
