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 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 .
