Failure to account for flexibility can have catastrophic consequences. For instance, a historical failure of a Jupiter ballistic missile in 1957 was directly attributed to the dangerous coupling between the control system and the sloshing motion of its liquid fuel. This example highlights the critical need for high-fidelity models that capture the dynamic coupling between the vehicle's rigid-body motion, its elastic structural modes, and other internal disturbances.
