Air India flight that lost altitude had triple hydraulic failure

The Indian Opinion

A sudden altitude loss on a passenger jet is alarming enough. Now the focus has shifted to the pilot-in-command's mandatory drug test, which required confirmatory analysis after an initial screening. The usual chatter about lax pilot testing misses the point: one preliminary result, which may turn out negative, does not indict the entire system. The real test is what the AAIB, now aided by Airbus and the BEA, finds in the flight data and cockpit voice recorders.
