The Aerial Phenomena Research Organization was one of the earliest UFO Investigative Agencies. It began in January 1952 and remained active until 1988. The Tuscon, Arizona based organization was started by Jim and Coral Lorenzen.
According to Wikipedia, “In 1969, a sizable portion of APRO’s membership elected to form a new group named the “Midwest UFO Network”; this soon expanded and became the Mutual UFO Network (MUFON), still active today.”
This is a collection of all the bulletins that we could find from the APRO archives. If you have some that are not on this list, and you would like to donate a digital copy, please get in touch with us at HQ@mufon.com.
This collection of their publication covers the years 1955 to 1987.
