This video of multiple unknown lights in triangle formation was filmed over Los Angeles, CA on the 18th May 2013.
Witness report: This was footage shot at MacArthur Park in Downtown Los Angeles. You will see the UFOs making a triangular formation in the daytime sky. They way these objects move you can tell they are not balloons or anything else. Take a look. Thanks Robert Bingham for having this and other events like it.
