PROBED ANALYSIS
The 1993 Lethbridge "Flight of the Triangle" sighting involves reports from three witnesses who observed dark triangular objects in the sky over Lethbridge, Alberta, on the night of August 11–12, 1993. The descriptions include a gray-black triangular object with red lights on each corner, moving silently and quickly, and performing an upward flip at a 45-degree angle. Investigations at the time did not identify any transponder-equipped aircraft in the area and noted incomplete radar coverage, leaving the sightings unexplained. The consistency in the sketches provided by the witnesses suggests some level of corroboration, although the absence of radar evidence and the lack of further official investigation leave the event open to interpretation.
