USS Princeton Pre-Encounter Radar Tracks

The guided-missile cruiser USS Princeton tracked anomalous radar returns for 2 weeks prior to the famous November 14 Nimitz FLIR intercept. Objects repeatedly descended from 80,000 feet to near sea level in seconds — a maneuver physically impossible for known aircraft. The objects loitered in the same area daily for two weeks. The USS Princeton's radar systems were considered among the most advanced in the fleet; technicians initially assumed equipment malfunction but could find none.
