The Apollo program, a pivotal moment in the history of space exploration, was not just a series of space missions but an enormous engineering and industrial endeavor. While the astronauts like Neil Armstrong are well-known, the construction of the spacecraft and rockets, an effort involving 400,000 workers and 20,000 contractors, remains less celebrated.

Key to this were the contributions of North American Aviation and Harrison Storms, its chief engineer. Storms, who joined North American in 1941, was instrumental in the development of advanced aircraft like the B-70 and X-15, which pushed aerospace technology boundaries. The B-70, for instance, was a high-speed bomber designed for “unchallenged military supremacy,” utilizing innovative techniques like “compression lift” and advanced steel fabrication.

Similarly, the X-15, a research aircraft, required the development of new fabrication techniques for the Inconel X alloy. These advancements in aerospace technology laid the groundwork for the Apollo program’s success​​​​​​​​​​​​​​​​​​.
