Where was the most recent UFO sighting?

i think this was a UFO sighting, i was driving home when i saw a dark blue triangle in the sky, this was on May 11 Saturday, at about 1:00 PM, 2011. i thought it was a kite at first but it was going so fast and it was so big that there was no way it was a kite. a UFO? i thought to myself. a minute after it disappeared a helicopter went in its direction. then i wondered if the government saw the UFO and tried to catch it.
