From a report filed by an officer of the National Guard, regarding the events she witnessed in the early morning of Friday, June 12th, 2015.
My unit approached the most populated area in our designated target zone, bringing with us as many empty troop-carrier trucks as we managed to find before heading out. We went in as fast as possible, with the desperate hope that we would be able to load up our trucks with anyone and everyone we came across, and then rush them back out of the area as quickly as possible, hopefully getting them out of the area about to be destroyed by the incoming meteor.
En route to our destination, we received radio communications, indicating that the meteor was beginning to slow down as it approached the surface. This made very little sense to us, however it did mean we had that much more time to save as many people as possible.
We had fully loaded two of our trucks, and sent them heading out of the risk-area. On approaching our next designated way point, we saw something strange in the sky overhead. Far above us, something seemed to... shimmer faintly, as it passed by us. Our radio had been filled with nothing but interference for a while, something we had anticipated as the electromagnetic effects of the meteor's approach affected us, so we could neither report it at the time, nor ask what we might be seeing. The object passed overhead, although its progress was difficult to track directly... we couldn't actually see it, the air in its vicinity just seemed to glow and shake. After it passed us, we went back to work, intent on our objectives.
The above report is the earliest reliable eye-witness account of the passage of the meteor. While not viewed directly, its passage overhead was detectable from the ground at this point, its outer core, as mentioned previously, having burned away after entry into the atmosphere.
