So little hard data is being released.
After looking at the document, I took this to mean the former (multiple on same plane/ship)
For the rest, I imagine they can conceive of explanations, but they lack sufficient data to explain with certainty.
There's no such thing. An anomaly that doesn't appear on multiple sensors is a defect with your sensor.
Yes, they probably have a lot more data, but they won't release it to the general public for "security reasons".
This is pretty clearly non-scare quotey security reasons territory. We are unsure if what’s on the scope is an adversary’s. Publishing a detailed quantification of how little we know and in what form would be a self goal.
