My father and i were watching tv a few nights after my 18th birthday. the tv began having lag spikes, but we did not pay much attention to it because we had just gotten a new direct tv system and figured it was just glitching out. a few minutes after that we heard a noise that was getting progressively louder,so we went in the front yard to see what was happening. when we got outside we saw a solid bal of blueish white light that was streaking through the sky with a helicopter not too far behind. the event only lasted a few minutes, but it felt like it lasted an hour. my first thought was that it was the helicopters front lights, but if that were the case, the light would not have had a cleary spherical shape. my father is not a believer of extra terrestrial life, but he also served in the air force reserves as a mechanic and has told me that he has never heard of or seen any aircraft that was like what we saw that night.
