A California witness at an Orange County beach reported watching what appeared to be a military jet chasing a sphere-shaped UFO about midnight on February 15, 2014, according to testimony in Case 54101 from the Mutual UFO Network (MUFON) witness reporting database.
Witnesses in California and Missouri reported similar incidents occurred on February 11, 2014, where the military was apparently chasing a UFO. See Military chasing UFOs? Witnesses in two states file reports. The description of the California object in the earlier case was also described as orb-like and occurred just four days earlier in nearby Anaheim.
