Project Blue Book was one of a series of systematic studies of unidentified flying objects (UFOs) conducted by the United States Air Force (USAF). It started in 1952, the third study of its kind, following projects Sign (1947) and Grudge (1949). A termination order was given for the study in December 1969, and all activity under its auspices officially ceased on January 19th, 1970. Project Blue Book had two goals: To determine if UFOs were a threat to national security, and to scientifically analyze UFO-related data. By the time the project ended, it had collected 12,618 UFO reports, and concluded that most of them were misidentifications of natural phenomena (clouds, stars, etc.) or conventional aircraft. According to the National Reconnaissance Office a number of the reports could be explained by flights of the formerly secret reconnaissance planes U-2 and A-12. A small percentage of UFO reports were classified as unexplained, even after stringent analysis. The UFO reports were archived and are available under the Freedom of Information Act, but names and other personal information of all witnesses have been redacted.

When Twin Peaks was rerun on the Bravo cable network in 1993, David Lynch wrote new introductions for each episode that were performed by Catherine Coulson as The Log Lady. The one for this episode was thus:
"My husband died in a fire. No one can know my sorrow. My love is gone. My dearest friend is gone. Yet, I feel him near me. Sometimes I can almost see him. At night when the wind blows, I think of what he might have been. Again I wonder: why?
When I see a fire, I feel my anger rising. This was not a friendly fire. This was not a forest fire. It was a fire in the woods. This is all I am permitted to say."
