The CIA Built a Plane That Should Have Been Impossible

The CIA wanted an aircraft that could fly higher, faster, and farther than anything that came before it. What followed was one of the most ambitious secret engineering projects in aviation history.

Known as Project OXCART, the program pushed engineers to create an aircraft capable of sustained flight at more than three times the speed of sound and at altitudes approaching 90,000 feet. At the time, some of the technology needed to accomplish it barely existed.

Engineers had to rethink almost everything—from aerodynamics and radar detection to engines, fuel, manufacturing, and materials. The aircraft ultimately relied heavily on titanium, and in one of the strangest twists of the story, some of the raw material was secretly obtained from the Soviet Union through intermediaries.

Behind it all was a hidden test facility in the Nevada desert, where engineers and pilots worked on a project that remained surrounded by secrecy for decades.

This documentary explores how OXCART was created, why its engineering was so revolutionary, the extraordinary challenges its designers faced, and why such an advanced aircraft ultimately had such an unusual operational history.
