The mystery of China Eastern Flight 5735 just got a lot darker. For over four years, we've waited for a clear answer on why a perfectly healthy Boeing 737-800 suddenly pointed its nose at the earth and didn't pull up. New data released by the National Transportation Safety Board (NTSB) in May 2026 under the Freedom of Information Act suggests this wasn't a mechanical failure. It looks like a deliberate act.
If you’ve followed aviation safety for any length of time, you know that planes don't just drop 29,000 feet in a near-vertical dive because of a "glitch." Modern jets are built with layers of redundancy. Yet, on March 21, 2022, MU5735 essentially became a missile, slamming into a mountainside in Guangxi at speeds nearing the speed of sound. The latest NTSB records indicate that while the plane was cruising, the fuel control switches for both engines were moved from "run" to "cutoff."
On a 737, you can't just bump those switches. You have to physically pull them up and then move them. Doing both at the same time is a conscious, manual choice.
The Struggle for the Controls
The most chilling part of the new information isn't just the fuel cutoff. It’s the sequence of events that followed. According to the Flight Data Recorder (FDR) analysis, seconds after the engines were starved of fuel, one of the control sticks in the cockpit was pushed forward with significant force.

This is where the "struggle" narrative gains weight. In many intentional crash scenarios, like Germanwings 9525, one person waits for their colleague to leave the room. Here, the data shows a series of inputs that suggest a fight for the soul of the aircraft. When an airplane is in a high-speed dive, the physical forces make it incredibly difficult to move the controls. If one pilot is trying to save the plane while another is forcing it down, the data looks exactly like what we're seeing in the MU5735 files—erratic, high-pressure movements that eventually ended in total devastation.
Why the Silence from Beijing
The Civil Aviation Administration of China (CAAC) has been remarkably quiet. In fact, they haven't released a final report even though it’s now 2026. Under international treaty, these reports are supposed to be public within a year or two. The CAAC’s last major update basically said, "We found nothing wrong with the plane."
- Mechanical Integrity: The CAAC confirmed no issues with the stabilizers, engines, or airframe.
- Weather: The sky was clear. No thunderstorms, no severe turbulence.
- Communication: The pilots didn't send a distress signal before the dive started.
When you rule out the machine and the environment, you're left with the humans. The NTSB data essentially fills the gap that Chinese officials have refused to address. By releasing the FDR details showing the manual fuel cutoff, the U.S. investigators are putting the focus squarely on what happened inside that cockpit door.
The Physical Reality of the Impact
To understand how violent this event was, you have to look at the crash site. Most plane crashes leave a "debris field" that stretches for miles. MU5735 created a crater 66 feet deep. The plane hit the ground so hard and so fast—over 700 mph—that it shattered into nearly 50,000 pieces.
The Flight Data Recorder actually stopped recording at 26,000 feet because the plane lost electrical power when the generators (attached to the now-off engines) quit. But the Cockpit Voice Recorder (CVR) kept going on battery power. The NTSB has reportedly reviewed some of these audio files. While they haven't released transcripts, the "struggle" mentioned in recent reports likely stems from the sounds of cockpit alerts mixed with human voices in those final minutes.
Lessons from Germanwings and SilkAir
We've seen this movie before, and it never gets easier to watch. When SilkAir 185 went down in 1997, or Germanwings in 2015, the initial reaction was disbelief. How could a pilot do this? But the data usually tells the truth long before the bureaucracy does.
In the case of China Eastern, the "national security" concerns cited by Chinese authorities for withholding the report suggest they're worried about more than just a mechanical fix. They're worried about the implications of a mental health crisis or a deliberate act of mass murder within their flagship industry.
What Happens Now
The NTSB’s release of this data is a massive nudge to the CAAC. It’s basically saying, "The world knows it wasn't the plane." For the families of the 132 victims, this isn't about blaming Boeing or the weather anymore. It’s about accountability for the crew's screening and the security of the cockpit.
If you’re a frequent flier, don't let this terrify you, but let it inform you. Aviation is safer than it’s ever been, but the "human factor" remains the most unpredictable variable in the sky. We need to push for:
- Transparent Reporting: International bodies must hold the CAAC accountable to ICAO standards for final reports.
- Psychological Support: Better peer-support programs for pilots to catch red flags before they reach the cockpit.
- Two-Person Rule: Strict adherence to never leaving a single person alone in the cockpit, regardless of the airline's home country.
The data is out there now. The "struggle" wasn't just in the cockpit; it's currently a struggle for the truth between two global powers.
