These links make good reading showing both sides of the alleged event. For me the second link says it all, like all UFO stories it has grown legs of its own and got bigger as time goes by. Simply put, the second link gives a very good account of what it most likely was, so for me no longer unidentified. The so called "cover up"... well there is a good explanation of that too. I give both links so that you can draw your own conclusions. For me nothing out of this world happened on that day.
