Today there were military helicopters in a fleet flying low. Soon afterwards, a military jet took off from EUG airport. The military aircraft are becoming more and more visible in this area. I recognize the noise of these aircraft and go outside to see, and most likely I will have my camera, as I did here. I tried to keep in mind that UFO's sometimes are in the area when these military aircraft show up. As the loud jet ascended and headed east, I tracked the jet as well as I could, since my camcorder does not have an eyepiece to frame the shot, but rather has a flip out monitor, which is difficult to track moving objects far away zoomed in tight. It was when I was looking back at the video file, that I did notice somethings dark moving fast what appears to be near the jet. This is near the end when the camera is looking over the roof line. Also, in the movement of the camera, I did notice perhaps the same unknown object before.
