I'm not going to DL some random PDF though, sorry.
Can you verify that this actually came from the Brazilian military?
This is pretty amazing if it's real.
Good work.

As a conclusion of the observed constant facts in almost all presentations, it is the opinion of this Command that the phenomenon is solid and reflects intelligence by its capacity to follow and sustain distance from the observers, as well as to fly in formation, and are not necessarily manned craft.
Based on the analysis of above-reported events, it is this Command’s opinion that, according to the information from the controllers, pilots and previously elaborated reports from I Cindacta (Air Traffic Control and Aerial Defense Center), that there are some points of coincidence regarding radar echoes, accelerations, illumination, velocities and behavior, either by technical detection or by visual contact.
2. Some of those coinciding points that we can name are those phenomena which exhibited certain constant characteristics, as follows:
a. Produced radar echoes, not only on the Air Defense System, but also on the intercepting airplanes simultaneously, with visual comparisons by the pilots.
b. Change in velocity, from subsonic to supersonic, besides hovering capability.
c. Varied altitude, from below FL-050 to altitudes above FL-400.
d. Occasionally seen as white, green and yellow lights, and sometimes no luminous indication.
e. Sudden acceleration and deceleration

The radar data is questionable.
following the movements detected on the occasion was severely thwarted by the fact that it was not possible to maintain visualization, regardless of the controllers’ efforts, because the contacts obtained were not strong enough to allow an initialization work.

I do want to know what your position on the topics of 'existence of ETs' and 'existence of UFO's' is tho...?? even if this particular story turns out not to be quite what it seemed....

The majority of UFO's seen by Terrestrial observers are actually Government drones/crafts which are unmanned but flawed due to some imperfections in design.
Originally posted by B.MorrisonHe's just pointing out where the 'evidence' isn't nearly as conclusive as the OP is intending. And you can see that clear as day, with the quote he supplied, about how the radar data is questionable.

your acclaim has reached a point where I'm not even reading your posts more than just to determine if you're debunking something or not and then if you are its just "damn! must be wrong!".
I do want to know what your position on the topics of 'existence of ETs' and 'existence of UFO's' is tho...?? even if this particular story turns out not to be quite what it seemed....I'm sure a simple PM would suffice, instead of trying to derail this thread, just to hear Phage's thoughts on something that doesn't pertain to this threads topic.

So if they come back and change something (even that accidentally) that actually made them achieve success and technological advancement...
...that means that maybe they will die or never exist.
Is that even reasonable..?
