The Manhattan Project Completion (1945)
The Manhattan Project, one of the most ambitious scientific endeavors in history, was completed in approximately 40 weeks from its full-scale initiation in 1942 to the successful Trinity test in July 1945. This top-secret project brought together over 130,000 people, including the world's leading scientists like Robert Oppenheimer, Enrico Fermi, and Richard Feynman, to develop the atomic bomb. The project cost approximately $2 billion (equivalent to $23 billion today) and resulted in the creation of the most powerful weapon ever devised by humanity.

The Apollo program, which culminated in the first human moon landing, was developed over approximately 40 weeks of intensive work following President Kennedy's commitment in May 1961. This period saw the establishment of NASA's Manned Spacecraft Center, the selection and training of astronauts, and the initial design phases of the most complex engineering project in human history. The program would eventually employ over 400,000 people, cost $25.4 billion, and achieve one of humanity's greatest technological achievements.
