Project X and Unconventional Aircraft

Summary

This CIA document refers to a project called "X" involving unconventional aircraft. It describes a design with a circular wing 30 feet in diameter and 1.1 feet thick. The project, funded by the U.S. Air Force, includes wind tunnel testing with a budget of $300,000. John Frost leads the project, based on ideas obtained from a German group after World War II. The Soviets are also said to have acquired information from this same group.

The document notes that if the objects seen were indeed in service, it would indicate rapid development by the Soviet Union. However, it questions why they would continue with conventional aircraft if they already had advanced technology. The report requests more information to properly assess the sighting.
