Officials claim doomed Germanwings plane flew to the end..

Remi Jouty, the head of BEA, is quoted by media sources as saying that the debris field in the French Alps where Germanwings flight 9525 crashed is ‘not characteristic’ of a plane that exploded in mid-air.. MORE: It would be more a plane that broke apart as it hit the ground, the official said..

At this point, investigators are being dropped by helicopter to the site of the crash.. The rugged terrain and weather conditions have complicated matters..

CNN reports, 

Investigators have managed to hear some audio from the flight data recorder, one of two so-called “black boxes” on the flight. The other “black box,” the flight data recorder, has not yet been found, Jouty said.

Earlier, French President Francois Hollande said the outside frame of the second “black box” has been found, though not the recorder itself.
