That’s why it’s important to look at all the reported cases to get a probabilistic measure. The 3 videos represent 2 cases that occurred. The DoD has over 300 unidentified cases currently. At least 18 exhibit flight characteristics that don’t seem possible.

The sensors are classified but saying the sensors can see 6-8 nm's away is not because that would not be telling our adversaries anything - that technology has been available for decades. Giving away a capability that our adversaries don't know we have would be bad. For example, navy personnel have been saying that submarines go far faster than what the public knows they can (but obviously they cannot say exactly how fast subs go)
