The black boxes from the Jeju Air plane that crashed in South Korea are the center of focus as investigators work to determine the cause of the deadliest aviation disaster of 2024.

The bereaved families visited the site on Wednesday for the first time since the crash for a traditional memorial service. They were bused to the site, where they took turns laying white flowers, knelt down and bowed deeply before a memorial table where food was placed. The food included “ddeokguk,” a Korean rice cake soup eaten on New Year's Day.

The damaged flight data recorder from the crashed Jeju Air jet in South Korea will be sent to the US for further analysis.
