Driving west on Midway Blvd. I came to a stop behind a few cars in the middle of the road, people were looking up to the North. I head a low humming and saw a pretty large white orb, inside was a small pill sized and shaped black/ metallic “UFO”. It was changing colors, moved abruptly up and down , east and West, then it hovered for a half a minute, and flew at an incomparable speed. It scared me badly, because I used to live near a military base and an Airport in MD, and have NEVER seen any craft like this, it barely made any sound! When it shot out of site, the cars started moving again, but during the incident a male in the car in front of me actually yelled out his window, “What the &$@% is that.” I knew we were all thinking what the heck it really was. I can tell you now, I’m no longer a skeptic when it comes to UFO’s.
