Final pics show Japan Airlines Flight 123 mins before crash that left 520 dead… & the critical failure that spelled doom

FOUR decades on, the doomed Japan Airlines Flight 123 crash remains one of the world's worst aviation disasters of all time.

Haunting final pictures show the jet just moments before it crashed because of a critical failure - killing 520 people on board.

Tragedy struck on August 12, 1985 when the Boeing 747SR-46 jet crashed just 62 miles northwest of Tokyo.

On board the jet were 509 passengers and 15 crew members.

Only four of them survived.

The flight, dubbed the "Titanic of Japan", took off from Tokyo and was headed to Osaka but tragically crashed in the remote area of remote mountain area of Mount Takamagahara.

And to date, it remains the worst disaster in the history of Japanese aviation.
