On March 21, 2022, China Eastern Airlines Flight 5735 dropped from cruising altitude in a near-vertical nosedive, slamming into a mountainside in Guangxi province at over 600 miles per hour. All 132 people on board were killed. It was China's deadliest aviation disaster in nearly three decades, and the crash profile was unlike almost anything investigators had seen before.

This documentary from Oratura, a channel with just 37 subscribers, walks through the investigation methodically. What makes this video worth your time is the question at its center: modern commercial aircraft simply do not dive straight down without cause. The flight data recorder and cockpit voice recorder both had to be excavated from a crater over 60 feet deep, and piecing together what happened required international cooperation between Chinese authorities, the NTSB, and Boeing.

Aviation accident investigations are a fascinating lens into systems engineering, human factors, and institutional transparency. This case is particularly complex because of the geopolitical sensitivities involved and the unusual silence around the final report. The video appears to lay out what is publicly known, what the physical evidence suggests, and where the official narrative still has gaps.

For anyone interested in aviation safety, forensic engineering, or how crash investigations actually work, this is a solid entry point into one of the most unsettling incidents in recent commercial flight history.
