The DNI concluded that the UFO's are likely physical things.

A multi-sensor confirmation would show identical simultaneous movements across different sensors and platforms. Everything short of that is probably explainable due to the specific limitations of individual sensors.
"Most of the UAP reported probably do represent physical objects given that a majority of UAP were registered across multiple sensors, to include radar, infrared, electro-optical, weapon seekers, and visual observation"
Page 4 of the PDF, first bullet point:
"144 reports originated from USG sources. Of these, 80 reports involved observation with multiple sensors."
The UAP event spans the time where a pilot or aircrew witnessed the UAP. During this time the UAP was confirmed by multiple sensors.
There is no language in the report to make it seem like the "confirmation" happened at different times or on different days. If that is what is meant, then the report is very misleading, but I don't think that is what is meant. What language from the report leads you to this interpretation?
Extraordinary claims require extraordinary evidence. So far the only thing that about this report has been how much hot air they can blow out of a human ass.
