Signs of fire were found on debris recovered yesterday from the July 28 Asiana Airlines cargo plane crash off Jeju Island.
“We do not know if it was an explosion or a blaze that started at a particular point and spread,” said Cho Tae-hwan, head of the committee in charge of the investigation. “But there are signs of fire on the pieces that we have.”
