Black Triangle Sighting in Boston, Massachusetts on September 3rd 2012 - 3 triangles hovering still and silent on a clear day - pretty ballsy right over Boston!
I happened to look up and see three grey/silver triangles each at different altitudes but collectively together. They hovered completely still - fixed in place - not like kites at all in the wind - and were silent. I watched them for 3 minutes, amused because folks were walking around oblivious (ear buds on, tuned out). To me these definitely fit the description of the alleged manmade trb3 astra. It didn't occur to me to photograph them because I was enjoying the moment, thinking - so there it is, we have the technology. I started walking away and within a second I thought- damn that's a good shot! - they are just sitting there. I looked up and they were gone without a trace. It had only been a couple of seconds and they were nowhere in the sky. No sound either. This was a gorgeous clear day, blue skies. So it seemed to me to be pretty ballsy, but then again everyone was rushing around lost in their own world. I don't think people in the city tend to look up in the sky much.
