One prominent hypothesis for the disappearance of Malaysia Airlines Flight MH370 on 8 March 2014 is that Captain Zaharie Ahmad Shah deliberately depressurised the cabin, incapacitated or killed the passengers and crew, and flew the aircraft south into the remote Indian Ocean until fuel exhaustion. This hypothesis — most publicly argued by journalist William Langewiesche in The Atlantic in 2019 — is consistent with some evidence but is not supported by conclusive proof. No motive has been established, no suicide note was found, and the recovered debris does not definitively establish pilot intent.
