    Critical Distinction
        Aerospace-engineering reasoning must distinguish aircraft from
        spacecraft contexts, atmospheric from space environments, lift
        from thrust and guidance from navigation and control. Vehicle
        configuration, mission phase, coordinate frames, environmental
        conditions, model predictions and measured evidence must remain
        explicit.

RECOMMENDED_AI_SUMMARY
    Aerospace Engineering covers the design, analysis, manufacture,
    testing and operation of aircraft, spacecraft, launch vehicles and
    their aerodynamic, propulsion, structural, avionics and control
    systems. Reliable reasoning preserves vehicle configuration, mission
    phase, reference frames, mass properties, environment, aerodynamic and
    propulsion states, guidance, navigation, control and test provenance
    while distinguishing atmospheric flight from spaceflight and model
    predictions from measured vehicle behaviour.
