TOP-SECRET AIRCRAFT
Many UFOS aren’t ‘flying objects’ at all, but planets, mirages or unusual atmospheric phenomena. On the other hand, some are exactly what they appear to be – ultra-futuristic flying machines – except they originate here on Earth, not in outer space. The CIA estimates that more than half of all UFOS reported in the US during the 1950s and 1960s were the nation’s own spy planes. The very existence of these aircraft was a carefully guarded state secret, and the military much preferred the public to speculate about aliens than to uncover the true facts. A new twist was added in the 1970s with the advent of stealth aircraft such as the F-117, and later the B-2. During their development and initial deployment, these were every bit as secret as the earlier spy planes, while the requirement to disrupt incoming radar signals made them the most oddly shaped aircraft in the sky.
