What happened
Approximately one hour after departing, the Boeing 707 suffered a complete loss of all hydraulic fluid from its utility hydraulic system. During the approach to Miami, the crew attempted to address the landing gear configuration. The flight engineer successfully performed a manual extension of the main landing gear.
However, efforts to manually lower the nose landing gear were unsuccessful. While passing the control tower, the aircraft's nose gear doors were observed to be open, but the gear remained in a retracted position. Despite this configuration, the crew managed to land the aircraft safely with no injuries reported.
Following the landing, the aircraft was raised to allow for further inspection. Technicians were able to extend the nose landing gear using the normal manual extension system. Subsequent testing in a hangar, which included retracting and manually extending the nose gear four additional times, showed no evidence of mechanical failure or malfunction in the gear itself.
