The preliminary investigation into what caused the fire on an Ethiopian Airlines Boeing (NYSE:BA) 787 on Friday is reportedly expected to take several days, with early indications suggesting the blaze burned in the overhead area towards the back of the plane. The incident puts a spotlight on the Dreamliner's carbon-composite technology and whether the jet can be cost-effectively repaired. Meanwhile, airlines continued to fly their 787s over the weekend, with passengers in Japan, the 787's major market, not canceling their tickets.
