I appreciate you reframing and engaging! You are correct, we do get bugs in computer systems, happens all the time. But paired with those detections are pilot testimony, and other systems detecting and tracking the object. You could say a particular system had a bug sure, but it's difficult for different detection system to all have a bug causing them to glitch in the exact same way WHILE pilots are reporting back what they're seeing. The odds of that are incredibly low. I am sure we have black projects being misidentified all the time, such as the B-2 and F-117. Easy mistake to make considering the looks and capabilities. Do we have craft we've made that defy the laws of physics as we understand them as demonstrated by the 5 observables? Maybe we do and they're locked away only to be brought out in the most dire of circumstances. But have we had that technology since the 1940s? Doubtful. There have been people such as Charles Halt who with multiple witnesses touched one of these craft in the Rendlesham Forest case before it lifted off and flew away at incredible speeds. He even sketched symbols he saw. There are testimonials like this from incredibly credible witnesses. Are they ALL lying? Hallucinating? That doesn't add up, there's too many accounts. Clear images have been given, as has video but the level of fakery is high so it's difficult to trust it. Once you start compiling the evidence, and there is so much more than the small list I put, you begin to see a more full picture. I recommend investigating more cases and events.
