India’s government is urgently inspecting all Boeing 787s after a devastating Air India crash that claimed at least 270 lives this week, the aviation minister said on Saturday, adding that the authorities were investigating all possible causes.

Viswashkumar Ramesh, 40, the sole survivor of Air India Flight 171, is among the ranks of those spared by fate.

Management installed by the Tata Group had spent three years struggling to undo a reputation for shoddy operations earned during decades of state ownership.
