Well, I guess technically, it was a UFO but only because *I* couldn't identify it. I was hoping others on this site could give me some information.
It was a canard aircraft, sounded like a military jet, single (or two close together) engine(s), swept wings (too high to see the canard), high and fast, white in color.
All the planes I found searching the web were, I believe, too small.
