Pilot error in crash that killed Mexico No. 2 official

MEXICO CITY (AP) - A final report on the helicopter crash last year that killed Mexican Interior Secretary Francisco Blake Mora and seven others said it was caused by pilot error.

Mexico's general director of airports and auxiliary services said investigators found no mechanical problems or evidence of an explosion.

Mr Gilberto Lopez Meyer said on Friday that the aircraft was flying through fog in near-zero visibility last November when the pilot changed course and the helicopter crashed into a mountainside south of Mexico City. He added there would not have been an accident without the route change.

The interior secretary is the Mexican government's number two official. He was the second interior secretary under President Felipe Calderon to die in an aircraft crash.
