The APRO Bulletin was the official publication of the Aerial Phenomena Research Organization which was founded in 1952 by Jim and Carol Lorenzen. APRO continued through the 1980s and below is a nearly complete collection of the APRO Bulletins for research use.
1975 and later – Special thanks to APRO Assistant Editor Richard Heiden for providing these files. Read a letter from Richard about the collection of these files on the bottom of the page.
(Note: Per Richard, some of the issues had the wrong volume number printed on them. The links and file names have the correct volume and numbers.)

Letter from Richard:
I started reading Coral and Jim Lorenzen’s books soon after I got interested in UFOs in the late 1960’s. But I didn’t join APRO until the summer of 1970. In his letter of Oct. 4, 1977, Jim Lorenzen asked me to become Assistant Editor of the APRO Bulletin, and I accepted. Actually, I did not have any input in editorial decisions, which would have been difficult in any event, considering that I lived in Milwaukee (as I still do), and there was no Internet in those days. My function was basically to translate correspondence and articles from Spanish and Portuguese, which I continued to do until the end of APRO—besides contributing other articles and book reviews.
In about 1986, when Coral Lorenzen’s health was failing, she asked me if I wanted to take over the Bulletin. Unfortunately, at that time I was about to start grad school, so I had to decline. I think she asked others too, but apparently no one wanted to assume the task that Coral had started on her own in 1952. After Coral’s death, Bob Marsland (APRO’s Deputy Director, who lived in Tucson) photocopied for me a collection of the back issues, which was my first opportunity to read the very earliest issues. (Bob is in the group pictures that appear in the 29:12 issue, p. 7; and in the 31:2 issue, p. 2. He passed away in March of 2009.)
I met Coral Lorenzen five times. First in August of 1973 when Jim was in Chicago on business (he was out tending to the business when I visited Coral at their motel near the airport). Again at the UFO Congress in Acapulco in April 1977; at the International UFO Congress sponsored by Fate Magazine in Chicago in June 1977; and at the APRO symposium in Cleveland in June 1981. And finally in June of 1983, when I visited the Lorenzens in their home in Tucson. Coral was a strong-willed, independent woman whose control of APRO unfortunately did not allow for sharing responsibilities to the extent that others could move right in when her health and Jim’s deteriorated so as to prevent their continuing with their organizational responsibilities. That is, not until it was too late.
In later years, the bulletins came out two at a time, with a mailing wrapper that also included editorial material. Each mailing wrapper was scanned following the FIRST of the pair of issues that it contained. At least three issues (including 32:10 and 32:11) were mailed singly, and would be recognized as such only because the NEXT issue has another wrapper scanned afterwards. Another pair of issues also had a 4-page questionnaire with it, which was scanned between the first issue and the wrapper.
A friend suggested that I edit a compilation of APRO Bulletins. The idea returned to my mind occasionally, but I never did anything with it. One thought I had about the project was to correct errors that had appeared in the original bulletins, and perhaps add important relevant information from other sources—such as if a particular case turned out to have an identification.
Of course, with the Internet age, it is now possible to put the entire file of the APRO Bulletins online for all the world to access. That is what you find here. In a few cases, I did note corrections to published typos in my own articles. However, the notations in the issues of the bulletin’s first few years were presumably made by Coral herself.

I am a MUFON Field Investigator who is researching a historic case 557676 It is believed they were interviewed by APRO at the time. I would love to add any additional information.
It was 9/2/1976 and the people were: Martin (Marty) Napoli, Arnold (Arnie) Goldman, and Jeff Brodsky. I have talked to all three and the stories match within expectation from so long ago. It occurred in N.E Ohio (Gates Mills). It was a ship which displayed a light sequence. When Marty (driving) turned off his headlights, the UFO shut down its lights. It then sped away. Marty believes a band camp of St. Joseph’s High School also had a sighting that night. We have a newspaper clipping where they reported it. This is one of those solid cases which deserves to remain well documented.
Hi, I was curious about “fireballs” specifically those seen over San Diego Ca. around Aug. 23, 2003 . I’m just curious if anyone else saw one up close(within 15 feet) or am I the only one. He didn’t give me a name or anything. Just told me to get up out of bed and go outside and look up. It floated out of a fog bank , passed by slowly, did a couple of things with the plasma flames in my presence (formed small vortices in a circular pattern and opened an iris in the plasma and showed me what was under the plasma flame). And then slowly floated off towards the ocean, and disappeared. I went back to bed and to sleep . time 3:33am.
Got any cool stories like that? I also have a crappy little drawing I made of the ship, if you want to see it, just write back I’ll send it to you. Thanks for reading, hope you liked it.
Do you realize what you call UFO’s is biblical? I am not a religious man, but I study the original Hebrew and Aramaic scriptures and they do tell us that we will be invaded. We are living in the 120th Jubilee cycle which is the last Jubilee cycle before Yahweh tells us He pulls the plug as we know it. Again, this has nothing to do with being religious. It is instructions on what is soon about to happen. Again, I am not religious and this has nothing to do with be religious. And you will not like what will happen when they arrive.
Thanks Richard for this gift to the UFO-interested community. We appreciate the hard work you have invested. May God bless you for it.
I downloaded all the files and look forward to many hours of enjoyable reading. They will provide quite a few good additions to my Internet UFO Bibliography Website.
Saying a prayer for the Lorenzens.
Does anyone know if any issues of APRO have anything on Carl Allen or The Philadelphia Experiment Story?
From my website;
As the years passed Allen became bitter at the unwanted publicity of his letters, and the simple fact that everyone but him was profiting from his story. In 1969, to “get back at them all,” he handed Jim Lorenzen of A.P.R.O. (Aerial Phenomenon Research Organization) a copy of the Varo Edition (of Morris Jessup’s book, The Case for the UFO) with the following “confession” attached to the second page of the
“All words, phrases, and sentences underlined on the following pages in brown ink are false. The below page and the top part of the following  were and are the craziest pack of lies I ever wrote. Object? To encourage ONR Research and to discourage Professor Morris K. Jessup from going further with investigations possibly leading to actual research. Then I feared invisibility and force-field research; I don’t now.”
“Allende still believes… that a U.S. vessel… disappeared from its Philadelphia dock and reappeared seconds later in the Norfolk-Portsmouth area, then disappeared again to appear once more in its original berth.” – Jim Lorenzen of A.P.R.O.
There is also a picture of Carl at APRO in 1969 I would like to try and get a better copy of.
If anyone could be of help that would be great.
I did find one in apro_jul_1969.pdf, if anyone comes across anything else thatr would be great
all of the links for pre-1975 issues aren’t loading. any idea why? they used to. i really enjoy checking out these old articles & would love to continue doing so! thanks for providing access to them, it’s amazing!
They should work now.
What ever happened to all the APRO research material that was accumulated over the years?
