Live missiles must always have what attached to prevent static electricity from igniting the rocket motor?

Explanation:
Static electricity can build up on a live missile as it’s handled or moved, and a spark during motor ignition could trigger the propellant. Providing a direct path to earth drains those charges so the missile stays at earth potential, preventing a spark. A ground wire offers a direct, low-impedance connection to the ground, making dissipation of static fast and reliable. Grounding straps can serve a bonding purpose but may be less robust in dynamic or rugged conditions. Insulation would trap charges and could increase risk, while shielding tape is for shielding or protecting surfaces, not grounding.
