Pasadena, California, near the San Gabriel foothills, United States
The Pasadena Police Helicopter Encounter
A Pasadena police helicopter pilot later described a large dark rotating object, likened to a cluster of balloons, pacing the aircraft at about 60 mph before apparently accelerating rapidly away near the Rose Bowl. A second aircrew member is said to have witnessed it.
Why This Case Matters
Professional police-aircrew testimony is potentially valuable, but this case's surviving public record is much later than the event and lacks the contemporaneous operational paperwork needed to validate the dramatic speed estimate.
Chronology
- Oct 1972 night patrol
- crew initially notices military-helicopter-like traffic
- dark rotating balloon-cluster-like object appears ~300 m away
- object reportedly matches helicopter speed
- later account claims rapid departure near Rose Bowl
- narrative published decades later
The Witnesses
Evidence
The following evidence types are documented for this case:
Conventional explanations: Large balloon cluster, dark unlit aircraft/helicopter seen under poor night geometry, parallax and distance/speed estimation error; separate ordinary helicopter traffic may have been conflated.
What Remains Unresolved
- Exact date
- second witness identity/statement
- Pasadena Police flight/dispatch logs
- helicopter type and route
- ATC/radar records
- basis for 'supersonic' estimate.
Key Takeaways
- Do not repeat the supersonic claim as measured performance. Until a contemporary police record or second independent statement is recovered, treat this as a source-work case.
