On the night of 2-13-13, at around 8:00 P.M., an unidentified flying object--an actual physical "vehicle", not a mere light in the sky--streaked across the L.A. skyline toward the general direction of Long Beach and San Pedro, rapidly followed by a helicopter that appeared to be trying desperately to keep up with the mysterious object. If anyone else in the L.A. area spotted this UFO on the night of 2-13-13, feel free to respond to this post.
