Wuzhou, China: The crash of China Eastern Airlines Flight 5735 crash continues to raise critical questions more than four years after the disaster, as newly surfaced U.S. investigative data points toward deliberate cockpit actions while Chinese authorities maintain silence, citing national security concerns. On March 21, 2022, a Boeing 737-800 operated by China Eastern Airlines plunged from cruising altitude into mountainous terrain in Guangxi, killing all 132 passengers and crew on board. The aircraft, en route from Kunming to Guangzhou, entered a near-vertical descent from approximately 29,000 feet, leaving investigators initially baffled due to the absence of distress calls or clear external triggers. Early findings released by the Civil Aviation Administration of China (CAAC) ruled out conventional causes such as mechanical failure, severe weather, or hazardous cargo. The aircraft was deemed airworthy, the crew qualified and medically fit, and no evidence of explosives was found. Flight data and cockpit voice recorders were recovered and analyzed with assistance from international agencies, including the National Transportation Safety Board (NTSB), yet interim reports issued between 2022 and 2024 stopped short of identifying a definitive cause, describing the event as “very complicated and very rare.” Attention began to shift toward possible human involvement after early assessments indicated that control inputs from the cockpit forced the aircraft into its steep descent. However, no official conclusion was publicly endorsed, and the investigation appeared to stall as updates from Chinese authorities became increasingly limited. A significant breakthrough emerged in 2026 following the release of previously undisclosed materials through a Freedom of Information Act (FOIA) request to the NTSB. According to flight data recorder analysis, both engine fuel control switches were moved to the “cutoff” position approximately 23 seconds before the recording ceased. This action resulted in an immediate loss of engine thrust, followed by autopilot disengagement and aggressive forward control inputs that drove the aircraft into a rapid descent. The loss of electrical power shortly afterward caused the recorder to stop, leaving the final moments of the flight undocumented. The cockpit voice recorder, which continued operating briefly on backup power, was successfully recovered and analyzed. However, its contents have not been made public. The NTSB confirmed that it does not retain copies of the audio, and access remains under the control of Chinese authorities, making it a crucial yet unavailable piece of evidence in determining the sequence of events inside the cockpit. While the available data suggests that the shutdown of both engines was unlikely to be accidental and is consistent with deliberate manual input, investigators have not identified which pilot may have acted or under what circumstances. The data also does not establish motive, leaving open possibilities ranging from intentional action to incapacitation or other in-flight scenarios. Reports speculating about a possible struggle in the cockpit have surfaced in some media outlets but remain unverified and are not part of any confirmed investigative findings. Despite the emergence of these critical details, the CAAC has yet to release a final accident report, well beyond the timeline prescribed under international aviation norms. Officials have indicated that disclosing further information could endanger national security or disrupt social stability, an explanation that has drawn concern from global aviation bodies and safety experts. Under standard practices, accident investigations are expected to produce a final report within one year to ensure that safety lessons are shared across the industry. The continued lack of transparency has left several fundamental questions unanswered. Without access to the cockpit voice recordings and a comprehensive official report, the exact cause of the crash remains unresolved.

Ankara, Turkey: Turkey has ruled out sabotage, explosives, and any form of external attack in the crash of a Turkish Air Force C-130 military transport aircraft near the Georgia-Azerbaijan border, according to early findings released as part of the ongoing investigation. The aircraft, a Lockheed C-130 Hercules, crashed on November 11, 2025, while operating a return flight from Ganja in Azerbaijan to Merzifon Air Base in Turkey. All 20 personnel on board, including crew members and military technical staff, were killed in the accident, making it one of the deadliest recent incidents involving the Turkish Air Force. Initial data from the time of the crash indicated a sudden and catastrophic in-flight breakup. The aircraft was cruising at altitude when it disappeared from radar without issuing a distress call. Tracking data showed a rapid and uncontrolled descent, with the aircraft breaking into multiple sections mid-air before crashing in Georgia’s Kakheti region near the Azerbaijan border. The wide debris field and separation of major components suggested structural failure occurred before ground impact. According to the latest findings cited by Caliber and supported by Turkish authorities, forensic examinations have found no evidence of explosives, missile strike, or any external interference. Investigators reported no traces of bomb residue, shrapnel, or chemical agents, effectively ruling out sabotage or a hostile act. Turkish officials have also dismissed circulating claims suggesting the aircraft may have been shot down, describing them as unfounded. With external causes eliminated, the investigation has now narrowed its focus to possible internal factors, including mechanical malfunction or structural failure. Preliminary assessments suggest that a critical structural component, possibly in the tail section, may have failed mid-flight, leading to the aircraft breaking apart into multiple sections. The exact sequence of events, however, remains under detailed examination. The aircraft had undergone modernization in recent years and reportedly completed maintenance checks roughly a month before the crash. Despite this, investigators are examining whether structural fatigue, system failure, or an undetected defect could have triggered the catastrophic breakup. Authorities continue to analyse data from the flight data recorder and cockpit voice recorder, which are expected to play a key role in determining the final cause. Officials have indicated that a comprehensive final report will only be released after full technical, forensic, and operational analysis is completed. Following the accident, Turkey temporarily grounded its C-130 fleet for safety inspections and deployed a large investigation team to the crash site. Wreckage recovered from the mountainous terrain has been transported for detailed examination as part of the probe. While early findings have provided clarity by ruling out external factors, the final report is expected to establish the precise cause and sequence of failures that led to the mid-air breakup of the aircraft.
