The pilot at the controls of a Germanwings jet that crashed in the French Alps accelerated the plane into the mountainside, killing all 150 people on board, according to French investigators.

France¡¯s BEA crash investigation agency declined to confirm growing evidence against the copilot before completing its own analysis, but the chilling new detail from a newly recovered second ¡®black box¡¯ seemed to corroborate prosecutors¡¯ claims that he killed himself and everyone else deliberately.

¡°A first reading shows that the pilot in the cockpit used the automatic pilot to put the airplane on a descent towards an altitude of 100 feet,¡± the BEA said in a statement.
