What could happen if an airplane operates above the never-exceed speed (VNe)?

Operating an airplane above the never-exceed speed (VNe) can lead to serious consequences, particularly structural failure or damage. The VNe is a critical airspeed that defines the maximum safe operating limit and is established to ensure the structural integrity of the aircraft is maintained under various flight conditions. Exceeding this speed can result in excessive aerodynamic loads that the aircraft's structure may not be designed to withstand. Such loads can induce severe stress on the aircraft's wings and fuselage, potentially leading to issues like flutter, which is a rapid, oscillatory movement that can severely compromise the aircraft's stability, and in extreme cases, can cause parts to break off or the aircraft to be uncontrollable.

The other options suggest less severe outcomes or misunderstandings of aerodynamic principles, which do not accurately reflect the dangers associated with exceeding VNe. Hence, understanding the importance of VNe is crucial for ensuring safety in aviation operations.
