Gosh, I've been writing a reply to your post AD for about an hour, and got logged out in the end and now it's lost and I'm so sad
So, once again:
In regards to the issues you pointed out I will answer them one by one
- diskshaped object - the first time we saw the object was after a good amount of observing the objects in the distance (above Troyan and the villages). While watching those, we were facing North, directly towards the area where Troyan and the villages around it were scattered, so you could definately say there is light pollution in that direction. Due to it, when we decided to face East for the first time, and we suddenly saw the light just above the hill, our eyes were still getting used to the lack of light in that direction. That's why it took about 30 seconds for us to manage to depict the dim red light that seemed to look like a full circle that was rotating non-stop according to the white light in the center. The body itself, became visible 40 or so seconds after we saw the red lights, we didn't see it as clearly as the triangular one, but we could well tell the outline of the body from it being a slightly darker shade of black from the nightsky behind it. I'm very aware of how the mind works, as this is an area that has been fascinating me since I was a kid, I've read a lot of books and articles about how it misinterprets information, and am willing to give room to the possibility that we've misinterpreted what we saw in the darkness. However, I think as I explained the reasons for its appearing in stages before our eyes, and after it became visible to the most, I can hardly say that my brain has misinterpreted what my eyes saw, as they did see it clear enough to reach the conclusion it was a black disk shaped with a white light in its center and a red set of dim lights on the edge of the body. And also, I can say it was one quite large craft, I can tell size because I know the distance between us and the craft, and taking that in consideration along with the distance between the center white light and outter ring of red pulsating lights, I dare say it was somewhere around 30 meters in diameter and the way it was rotating slowly just a couple of meters above the top of the hill, blew me away.
- triangular object - after a few hours of trying to take photos of the objects in the distance and not managing to do anything that could be considered a success, we just gave up and thought that it's much smarter to observe these guys and try to see all of the details, and remember them as best as we could. The reason for this to be a tiring process, was that my friend was short of memory on his phone, and after trying to take a photo, and it coming black, we deleted it, and tried to take another, and so on and so on. All in all, we were missing the sighting and just decided to leave that as we realised we weren't equipped for documenting our experience. Also, when the triangular craft first appeared, it was a pale red dot that was copying the movements of the diskshaped object below, it maintained that way for about ten minutes, we never knew or expected that it will decide to leave the area with getting to a lower altitude and passing between us and the lights from the populated areas making it the clearest object we managed to see. We were more like stunned with scare when it passed in front of us, we couldn't believe we were seeing all of the details I explained in my report, seeing this triangle and the way it moved was the most amazing part of the whole experience in visual aspect.
- regarding the point you raised about these being military - well, when I originally wrote the report (and I haven't changed it since) I was a bit more naive, I was more willing to jump on the ET believer wagon. Now, that I've dug up quite more information and that I got into all of these conspiracy theories, black projects, etc (in short, I've gotten tons smarter since few months ago), I just don't know what we saw. But I know what we didn't see - conventional crafts and choppers. Probably due to language barrier obviously I didn't manage to stress enough on a few important things - first, the lights that were on our altitude and that were manouvering.. just for a comparison, I've went through a number of videos of air shows after our sighting. Well, yeah, they do catch the eye, but in comparison to the manouvers we observed... They were light years behind the cabalities of the objects we observed. My not so perfect English and specifically the lack of knowledge in words used for description of types of flying and manouvers, probably prevents me from explaining clear enough why I know this is advanced technology. In short, I am stating that the lights on our altitude flew in ways no conventional, or even military craft, that we know of are capable of doing (apart from black projects, of course).
Also, I obviously haven't stressed on this in my initial report - the rotation of the triangle according to its center happened suddenly - it was so quick that it was almost impossible to actually track the rotation with our eyes, it was like this /\ at one moment, and the very next moment it was already turned sideways. I'm not saying that there was no movement, but am saying that it was so amazingly sudden and quick that it made me swallow my dictionary the first time we saw it rotate. Also, there was absolutely no fluctuations in its position after a rotation has occured - absolutely no trembling or uncertainty, from one position, to another. And we could observe at least 6-7 rotations before it got very far away to tell its shape anymore. Also, the fact that it was flying in a manner that is against all logic doesn't ring an alarm for you guys? This is in regards to it's vertical position and the fact air resistance wasn't a factor for it's flying, just to clarify.
In addition to the arguements behind my belief we saw non-conventional advanced technology - take a look at my description from the report regarding the object that we managed to take photos of. That also points to the validity of my claims that we saw something far more advanced than our usual military crafts.
The last argument that I have about the lack of any choppers or conventionally driven aircrafts that night was the fact there was NO sound at all, throughout the whole night. Besides the mountain echoing with dog barking from all sides.
- regarding the fact memories can change with time - I know about this (as I said, I have been keeping myself informed about the ways the brain works for quite some time), however, I have to outline this - between the time of me writing down our experience and the time it happened, I happened to have told this story prolly more than 30 times to the very last detail of it. I have never changed the story a bit, and because of that, I know every single detail by heart, and it's all due to the following - when we decided to forget about trying to take photos of the objects, we decided it is very important to observe really carefully all that was happening and remember each and every detail in its best. So, that was my mission all along that night - watching closely, trying not to miss even the slightest happening in the skies, and of course, remembering everything as if my life would count on these memories in future. Throughout the night we continously corroborated with my friend, regarding what we were seeing, doublechecking every interesting thing (and all we were seeing was interesting). I have to say with all certainty, everything that you have read in the report has happened the way it was described. Prolly, I will rewrite it soon, to make it much clearer and easier to read and digest, but def not right now

Thank you very much for raising those points in your post, AD, you helped me with shedding light on some aspects that I haven't covered in the information I presented up till now, also thanks for taking the time to go through all of the info presented, I hope your eyes don't hurt a lot

. All in all, we failed in bringing back proof to back up our claims because we weren't equipped to gather such, but at least we brought back well-structured information and detailed observations. And hopefully, with everything pointing towards the repetitive nature of this phenomenon, it is completely in the realm of possibilities that we manage to bump into those guys again, this time completely armed for bringing back evidence to discussion.
Now, I have to say I don't have anything pointing towards a certain answer regarding the origin of the "operators" of those crafts, but still, I think what we observed was not a test. A very simple reason - if the military were conducting tests, would they make such incredible and obviously dangerous manouvers above populated areas? I remind you that we're talking about the military here, and if they were testing the capabilities of some new experimental crafts in a certain environment or some military excersises, they wouldn't be doing that above populated areas such as Troyan and the many villages scattered around. And let me remind you that the manouvers we saw I compare to airshows (and still find them incomparable), so yes, one could say that those were some nasty mindblowing dangerous manouvers. And the military usually like to keep the risks to the lowest, especially about something secret. Heck, the last object was hovering meters above a building in the forests nearby, although compared to the manouvers, that was nothing. So, in my opinion what we observed was not a test, whoever those were, I think they appear in that area repeatidly because there is something of value to them and are either looking for it, or already found it. Now, who these are, and what is this thing of value, I have absolutely no idea and don't dare to speculate. So, I'd be happy to discuss this matter as well - about whether what we saw was a test, or was activity with a certain goal (that is, in case we hypothetically take the more likely possibility for a fact - that these were military crafts).
Thanks again for bringing other aspects to the discussion, I'll be happy to see your further thoughts about this AD

p.s. I think I'll need to rent another life to get indepth with all of the information presented on this site! You guys have done an amazing job and I bow to you in awe! Now back to getting myself updated with the world of UFOlogy (Rich, thanks for the link to "Billion $ Secret", I enjoyed that one very much!)
