Apparently so...Yes, 160km/h over cruising speed makes stuff fall off?

The maximum operating speed (VMO/MMO) for the Boeing 737 MAX 8 is Mach 0.82 (or approximately 541 knots / 623 mph / 1,003 km/h), which serves as its core "do not exceed" speed limit. [1]
Key Speed Limitations
- Maximum Operating Speed (MMO): Mach 0.82 at higher altitudes where compressibility and Mach buffet become critical.
- Maximum Operating Limit (VMO): 340 knots Indicated Airspeed (KIAS) at lower altitudes.
- Normal Cruise: Typically operates comfortably around Mach 0.79 (530 knots).
- Overspeed Exceedances: Severe structural stress or steep dives (such as emergency descents or uncontained events) can push the aircraft past these maximum design limits, risking structural damage like control surface failure or rudder separation.
