Davis-Monthan Air Force Base, Tucson, Arizona, United States
The Davis-Monthan B-36 Discs
On 1 May 1952, Major Rudy Pestalozzi, an intelligence officer at Davis-Monthan AFB, reported seeing two bright disc-like objects overtake a B-36 bomber and pace it near the base. He later told atmospheric physicist James McDonald that the B-36 crew also observed the objects and that he filed a subst
Why This Case Matters
Potentially a high-grade military multi-witness case if Pestalozzi's original report and the bomber crew statements can be recovered.
Chronology
- 1 May 1952 Pestalozzi/airman observe discs near B-36
- bomber reportedly radios/request landing
- Pestalozzi interrogates crew and files report
- case enters Blue Book-era corpus
- 1960s James McDonald interviews Pestalozzi
The Witnesses
Evidence
The following evidence types are documented for this case:
Conventional explanations: Conventional aircraft, reflections, balloons or misperceived objects remain possible. The reported pacing manoeuvre is the key extraordinary element but cannot be assessed rigorously without the original statements and timing.
What Remains Unresolved
- Original Air Force/Blue Book case file
- names and statements of B-36 crew
- flight logs
- radar data if any
- exact route/timing
- Pestalozzi's complete original report.
Key Takeaways
- The case is promising but source-fragile. Do not present McDonald's later interview as equivalent to an intact 1952 official file.
