Project Mogul successfully used this effect to detect a nuclear explosion at a considerable distance.

He originated Project Mogul, an early program to detect Soviet nuclear weapons tests.

They called it Project Mogul.

In 1946, Project Mogul was given a top-secret classification with the highest priority.

Since the Roswell debris no longer exists, the Air Force cannot prove that it was from Project Mogul.

For example, Project Mogul used high-altitude observation balloons to monitor Soviet nuclear tests.

Constant altitude control and polyethylene balloons were the two major innovations of Project Mogul.

The first, released in 1995, concluded that the reported recovered material in 1947 was likely debris from Project Mogul.

Project Mogul was a research project designed to assess the feasibility of detecting Soviet nuclear tests by monitoring low-frequency acoustics in the upper atmosphere.

Project Mogul was a highly compartmentalized program, with many participants unaware of the true nature of the research.
