Boeing was generating optimism. Then on Thursday a 787 crashed, raising the specter of fresh problems for Boeing and altering the message it planned to send.

Officials say at least 270 bodies have been recovered, while the lone surviving passenger is still under observation for some of his injuries.

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.
