Not from this report, but these quotes are crazy:

> "In this country we've had incidents where these UAPs have interfered and actually brought offline our nuclear capabilities" [1]

> "We also have data suggesting that in other countries these things have interfered with their nuclear technology and actually turned them on, put them online." [1]

How is stuff like this possible or is it just hyperbole?

This seems awfully brief and doesn't have much detail. The tittle says it's a "preliminary" report. Is this the expected UAP report or just a preliminary document about it? I would want to see summary statistics for each reported incident and descriptions of the most compelling phenomenon. This document raises a lot of questions and answers few. The document says they have 21 reports of UAP that "appear to demonstrat…

If you're curious, this previously released footage is quite detailed.

This part caught my eye.

    These objects include birds, balloons, recreational
    unmanned aerial vehicles (UAV), or airborne debris 
    like plastic bags
It never occurred to me how utterly "alien" a wind-borne plastic bag's behavior might seem on radar.

A constantly shifting radar cross section, sudden directional changes no "actual" flying craft could manage, etc. After all it's an object with significant surface area but nearly zero mass being buffeted around in a region of the atmosphere with swirling wind currents.

Depending on the angle, the radar cross-section of a modern stealthy aircraft is reportedly about the same as a small bird or even a bumblebee. So the radar cross section of an airborne plastic bag or balloon would be pretty similar.

That said, I think the visual reports and videos from military aviators are pretty clearly describing something else.

Earlier quoted context omitted.

> I'm also not really impressed by their idea to use "advanced algorithms" and "machine learning". Are UFO encounters so frequent we need to resort to big data? I had that same thought - on first read this report seems to contain summary analysis of 144 UAP incidents. Not the sort of numbers that immediately make me think "I need ML to process those!"

144 _reported_ incidents. They also talk about how some of the cases going unreported. It would make sense to sieve through the radar data (I'd guess all the ATC radars are being recorded, because why not?) to look for those.

Most ATC now uses secondary radars. Those generally only pick up aircraft carrying transponders.

Nine pages? All this hoopla for the month leading up to the release and we get NINE measly pages with no supporting documentation? am I missing something? I expected to see something similar in quality/detail to an FAA accident investigation, this is a worthless executive summary.

I would not call it a report either, this is a request for more funding, the last sentence is: > The UAPTF has indicated that additional funding for research and development could further the future study of the topics laid out in this report. I would be more interested in a BEA style analysis of each incident. But at least it lays down some possible causes: - Airborne Clutter - Natural Atmospheric Phenomena - USG or…

The fact they don't include "just other normal planes" in that list calls into question the quality of this whole document. It really seems like this document was just thrown together with no real intent to get into the weeds on the reports. It does also seem like they are trying so hard to be vague to avoid running afoul of information classification rules. The White House needs to tell them to stop going so overboard with classification. Overclassification is a real problem in government.

A reminder that UFO stands for Unidentified Flying Object. This is just a report on what the military saw in the air and could not identify. It neither confirms nor denies popular ideas about aliens visiting earth. In most cases, you can guess these are probably aircraft from other countries. In some cases, they may be experimental aircraft being developed in secret by some organization or other. I am someone who thi…

Do you really think there is a single human being that reads HN and thinks "UFO" means 100% aliens? I sorta doubt anyone here needs such a reminder.

> "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." Yeah, if we could just get a copy of that data real quick, that'd be greeeaat.

rationally, that would fall under 'sources and methods' which the DOD/DNI/TLA are not going to release.

They care far less about the data than the system to get the data. Releasing it provides potential enemies information on systems capability.

I'm loving the conversation here. I cannot imagine how little the DNI cares about this.

From the report: "We currently lack data to indicate any UAP are part of a foreign collection program or indicative of a major technological advancement by a potential adversary."

Some weapons systems may be configured to automatically power on to a more ready (as opposed sitting in low power sleep mode) mode (not launch) when unknown objects appear on a sensor system. Whether this is a wise way to do things stands to be seen.
