Incident Details
On February 19, 1978 at approximately 1:20 p.m., radar operators monitoring two independent systems in Minnesota detected a large, solid object. The operators observed the object ascending rapidly immediately after one operator switched his system to manual mode.
Observed Behavior
The object demonstrated apparent evasive actions, including stopping, starting, and descending maneuvers. One operator tracked the object traveling approximately one mile in one second, equivalent to roughly 3,600 mph. The object also exhibited vertical movement described as occurring "instantaneously," suggesting extraordinary acceleration capabilities.
Significance
The incident represents a significant radar tracking case involving multiple independent detection systems, suggesting corroboration of the sighting. The object's apparent response to the operator's equipment adjustment raises questions about potential awareness or sensitivity to radar emissions.
