UFO detected by radar in Labrador in 1963

Summary

In August 1963, an air base in Labrador recorded an aerial phenomenon that remained on radar for almost 10 hours. Two objects, two miles apart, were observed at altitudes between 60,000 and 80,000 feet. Despite multiple attempts, T-33 interceptors failed to visually identify them, though radar contact was maintained. The objects displayed vertical movements and altitude fluctuations, suggesting a natural explanation.

The official evaluation concluded it was likely a balloon with a radar corner reflector, a common hypothesis in cases where visual contact is impossible. Balloons can travel long distances and, if small or transparent, would be hard to see from fast-moving aircraft. This explanation, while not definitive, fit the available data and ruled out technical malfunctions or astronomical phenomena.
