They could conceive of no explanation for any of them..
They have a lot of data and cannot explain much.
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.
Ok, you detected what exactly? At which frequencies? Power? BW? Does it look like something (unmodulated signal? Modulated? How?)? Do you have a recording of it?

> "Some UAP appeared to remain stationary in winds aloft, move against the wind, maneuver abruptly, or move at considerable speed, without discernable means of propulsion. In a small number of cases, military aircraft systems processed radio frequency (RF) energy associated with UAP sightings."
