The chief engineer for this West Coast landmark also designed gantries for the Saturn rockets
The Final Jeopardy clue for Tuesday, September 15, 2026, appeared in the category “Landmarks” and read: “The chief engineer for this West Coast landmark also designed gantries for the Saturn rockets.” The clue points to one of the most recognizable structures in the Pacific Northwest, a futuristic tower built for the 1962 Seattle World’s Fair.

What Is the Space Needle?
The correct response is the Space Needle. The landmark’s chief engineer was John Minasian, a structural engineer from California who was brought in to help finalize the tower’s engineering. He had specialized experience with tall structures and had also worked on rocket gantries connected with the Saturn program.
That background made him particularly well suited to a project like the Space Needle, which combined an unusual shape with significant structural demands. The tower had to withstand strong winds and earthquakes while supporting an observation deck and rotating restaurant high above Seattle.
John Minasian and the Space Needle
Minasian served as chief engineer for the Space Needle project and reviewed earlier engineering work before helping strengthen the final design. His expertise was especially important because the tower was unlike a conventional office building or skyscraper.
The Space Needle’s foundation was engineered to make the structure exceptionally stable. Its massive base was designed so that the tower’s center of gravity would remain close to the ground, helping it resist the forces associated with wind and seismic activity.
The Saturn Rocket Connection
The second half of the clue is what makes the answer distinctive. Minasian had experience designing rocket gantries for NASA, including work associated with the Saturn rockets used during the Apollo era. That aerospace connection fit naturally with the Space Needle’s futuristic identity.
The Seattle landmark itself was built during a period when the American space program was becoming a major part of national culture. The 1962 World’s Fair had a strong science-and-future theme, so the involvement of an engineer with rocket-launch infrastructure added another direct connection to the Space Age.
A Landmark of the 1962 World’s Fair
The Space Needle was created as the signature structure of Seattle’s Century 21 Exposition. Construction began in 1961, and the tower was completed in time for the fair’s opening in April 1962.
Its appearance was intentionally futuristic. Even the original paint scheme used names such as “Astronaut White,” “Orbital Olive,” “Re-entry Red,” and “Galaxy Gold,” reinforcing the fair’s fascination with space exploration and technology.
Why This Final Jeopardy Clue Works
This clue works because it links two very different structures through one engineer. Contestants needed to recognize that the West Coast landmark was associated with John Minasian and then connect his structural-engineering career to NASA’s Saturn-era launch facilities.
The correct response, the Space Needle, fits every part of the clue. Minasian served as its chief engineer, had worked on rocket gantries, and helped create a landmark that became one of the clearest architectural symbols of America’s Space Age optimism.
