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.

As India makes a thorough sweep of its fleet, the United States has already made a decision on Boeing 787s in use around the country. Officials from the U.S. determined they have not seen any immediate safety data that would require halting Boeing 787 flights following the accident, according to Reuters .

Air India flight 171 crashed on a building minutes after takeoff near the airport in India’s western city of Ahmedabad.
