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.

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.

Following the crash, the Directorate General of Civil Aviation (DGCA) instructed the airline to conduct detailed inspections of its Dreamliner fleet.
