What was the flight number of the aircraft that crashed in Lost?

The aircraft that crashed in Lost was Oceanic Flight 815. The plane was flying from Sydney to Los Angeles when it broke apart over a remote island in the South Pacific.

Flight 815 supplies the series with its original group of survivors and gives the show its opening catastrophe. The survivors are divided between the plane’s fuselage, tail section, and later-discovered parts of the wreckage, allowing the story to introduce characters gradually.

Oceanic Airlines is fictional, but the flight number became one of Lost’s most recognizable pieces of mythology. Later episodes reveal that the crash was connected to the island’s electromagnetic properties and to actions involving the Dharma Initiative.

Viewers sometimes confuse Oceanic Flight 815 with Ajira Flight 316, the later aircraft used by several characters in an attempt to return to the island. They are separate flights in the story and have different roles in the plot.
