Grieving mother Lee Hyo-eun returns every weekend to the airport where her daughter and 178 others died last year, desperate for the truth about South Korea¡¯s deadliest airline disaster.

Jeju Air Flight 2216 was coming in to land at Muan International Airport from Thailand when it struck a flock of birds and was forced to make a belly landing that sent it crashing into a structure at the end of the runway.

Only two flight attendants seated in the tail section survived.
