This 1971 emergency procedures page from a U.S. Air Force F-4 Phantom manual (Change 1, effective 15 September 1971) instructs aircrews on how to safely land with hung or unexpended ordnance, ranging from napalm canisters to CBU cluster bombs and CS gas munitions. Printed sideways on distinctive yellow paper for quick identification, this type of emergency checklist reflects the real hazards Vietnam-era combat aircrews faced when weapons failed to release cleanly during a mission, requiring careful judgment calls about jettisoning, returning to base, or attempting a landing.
