All 179 victims who died in Jeju Air plane crash have been identified, authorities confirmed. Families will be taken to the site Wednesday to pay their respects.

An expert has questioned whether birdstrike was the sole cause of the deadly plane crash in South Korea. Speaking on Australia’s “Today” show, aviation expert Professor Ron Bartsch said something more “sinister” could be at play.

Two people, both flight attendants, are the only survivors of the crash and are being treated at South Korean hospitals.
