A restaurant owner described witnessing the Jeju Air plane crash and recording videos as it happened. “Every time I closed my eyes, I kept seeing afterimages of the blast.”

Officials said it could take up to 10 days to prepare the dead for transport, with the uncertainty adding to the shock and grief of relatives packed into an airport hall.

Aviation safety analysts said they expect officials investigating the crash, which killed 179 people, to look into the location and composition of a structure housing an antenna.

A Jeju Air passenger jet carrying 181 people from Bangkok sped off the runway and burst into flames. Two crew were rescued in what was the country’s worst air disaster in decades.
