A Florida witness driving over the Timuquana Bridge on Jacksonville's west side reports watching a "dark triangle" UFO between 300 and 400 feet in the air and moving between 40 and 60 mph, according to December 6, 2011, testimony from the Mutual UFO Network (MUFON) witness reporting database.

"I observed an apparent dark triangle about the size of a plane, with three uniform lights, one at each corner of the triangle, but with no flashing FAA lights," the witness stated. "I am quite used to seeing many jets and planes regularly, as I live in close proximity to Naval Air Station Jacksonville, and this was not a plane."

The object was flying very close to ground level.

"It was flying at an altitude of maybe 300-400 feet, at a speed of 40-60 mph. I noticed it approaching from the north, which was to my left as I was headed east on 103rd Street and almost on the bridge. The triangle slowly flew overhead to the south and I lost sight of it through the trees as I began to cross the bridge."
