Washington D.C. UFO Flap - July 1952 (Carousel Incident)

Executive Summary

The Washington D.C. UFO incidents of July 1952 represent the most significant UFO events ever to occur over the nation’s capital. Dubbed the “Carousel” incident due to the circular movement patterns of objects on radar, these sightings involved multiple radar installations, visual confirmations, and military response, culminating in the largest UFO press conference in Air Force history.

Conclusions

The Washington D.C. UFO incidents of July 1952 remain among the most significant and well-documented UFO cases in history. The combination of multiple radar confirmations, experienced observer testimony, and government response makes this case a cornerstone of UFO research.

Whether representing genuine anomalous phenomena or sophisticated misidentification of conventional causes, the Washington sightings demonstrated the complexity of UFO investigation and the challenges facing both researchers and government officials in addressing unexplained aerial phenomena.

The case established patterns of government response, scientific analysis, and public interest that continue to influence UFO research and policy to this day.
