Given that the term "flying saucer" seems to be a misnomer from Kenneth Arnold's report that described the motion of the observed object as being "like a saucer skipping on a pond" and his sketch of the object shows something that looks a bit like a flying wing (http://photos1.blogger.com/blogger/4376/798/1600/Kenneth%20Arnold%27s%20Drawing%20Top%20%26%20Side.jpg http://photos1.blogger.com/blogger/4376/798/1600/Kenneth%20A...) which notoriously have a bucking or skipping motion in the air, it would be fairly weird if a disc-shaped object were involved. Edit: there's some speculation it might have been the German Horten Ho 229: http://fc09.deviantart.net/fs70/i/2011/159/e/d/horten_ho_229_by_tr4br-d3icg18.jpg http://fc09.deviantart.net/fs70/i/2011/159/e/d/horten_ho_229... It would be like you giving me an inaccurate description of something based on someone else's report, and me mangling your description into something that just happened to be very much like the original. It's not impossible, but you'd have to be pretty optimisic to call it remotely plausible.
