The video from the ground sees the plane exploding into a fireball.
A local fire official said the crash had likely been caused by a bird strike and weather conditions.
But others suggested the crash may have been caused by the landing gear failing.

Just two days ago, a passenger claiming to have travelled on the same plane said it had an engine shutdown as people were boarding.
According to Yonhap News Agency, a passenger who boarded the Jeju Air Flight 7C2216 said: “I was on the same plane at the time and the engine shut off several times.”
He said he’d set off from Muan International Airport for Bangkok and became worried: “I told the flight attendants and they said there was no problem.”
Other passengers, he claimed, also had concerns and the plane was delayed for an hour “due to airport issues.”
