1952 Washington, D.C. UFO Incident:
The 1952 Washington, D.C. UFO incident (sometimes called the "Washington Flap" or the "Washington National Airport Sightings") was a series of UFO sightings over Washington, D.C., primarily on the nights of July 19–20 and July 26–27, 1952. The case is one of the most significant ever investigated by Project Blue Book and directly triggered the formation of the Robertson Panel.

Kenneth Arnold Sighting:
On June 24, 1947, private pilot Kenneth Arnold departed from Chehalis, Washington, aboard a single-engine Call Air A-2 aircraft, bound for an air show in Pendleton, Oregon. En route, Arnold detoured to assist in the search for a United States Marine Corps transport plane that had reportedly crashed on the southwest slopes of Mount Rainier, Washington.

Lubbock Lights:
The Lubbock Lights were a series of UFO sightings that occurred in and around Lubbock, Texas, in August and September 1951. The case is one of the most significant and most discussed investigated by Project Blue Book, in part because of the credibility of the witnesses and the existence of photographs.

The Mantell UFO Incident refers to the death of Kentucky Air National Guard pilot Captain Thomas F. Mantell on January 7, 1948, while pursuing an unidentified flying object over Godman Field, Kentucky. It is one of the earliest and most widely studied cases associated with Project Blue Book and its predecessor programs.

Nash-Fortenberry Sighting:
The Nash-Fortenberry Sighting was a UFO incident that occurred on July 14, 1952, near Newport News, Virginia, and was investigated by Project Blue Book. It is considered one of the most credible sightings of the early 1950s due to the professional background of the witnesses.
