On March 21, a China Eastern Airlines 737-800 crashed during the cruise phase, a typically safe flight segment, killing all 132 on board. The aircraft reportedly entered a rapid descent, reaching speeds of 30,000 feet per minute, which raises questions about potential causes such as runaway trim or intentional actions. Speculation about pilot suicide or mechanical failure is prevalent, though many argue that a power loss at cruising altitude should not lead to such a drastic outcome. The intact fuselage seen in videos suggests that in-flight breakup is unlikely, but the investigation is ongoing to determine the exact cause. The recovery of flight recorders is crucial for uncovering the circumstances surrounding this tragic incident.
