Hours after a Jeju Air plane crash-landed and burst into flames, killing 179 people on board in the worst aviation disaster on South Korean soil, a photo of an aircraft's burnt out fuselage was shared in social media posts that falsely claimed it showed the wreckage.

The deadliest accident in aviation history occurred in 1977, when two Boeing 747 jumbo jets collided on a foggy runway on the Spanish island of Tenerife, killing 583 of the 644 people on board the planes. Spanish investigators blamed the captain of the KLM 747 for taking off without clearance from air traffic controllers.

The investigation into the crash of a South Korea passenger jet gathered pace on Wednesday as bereaved families began to prepare funerals after authorities finished formally identifying the 179 victims of the country's worst air disaster.
