A survivor of the Air India Express flight crash in Kerala on Friday today recalled the anguish of fellow passengers after an accident that has killed at least 18 people. "This is a huge tragedy. We had put our hands on the seat in front of us to balance ourselves while trying to survive the fall. As the plane crashed, it split into two pieces," the survivor, one of the five patients admitted to the Aster MIMS hospital in Kozhikode, told news agency ANI.
