Bright light several thousand feet over the Owens Valley near Bishop, California. Attacked by airplanes and left at high speed

Long time ago, in late 60s.  Bright light in clear sky over Bishop, CA was witnessed by hundreds of residents.  It was surrounded by a dayglow type of flourescent green vapor. When 4 or 5 fighter planes came from the south and flew straight at it, it accelerated almost vertically in what would approximate the speed of a shooting star. I have ruminated over this for years and feel that I might add something not known.  I had a communications receiver tuned to the frequency that the chase planes were using to communicate with the Blackbird which was being tested at the time over the Owens Valley.  I went in the house in time to hear a pilot say "have sustained some damage-request to land at Tonopah"  Reply was "permission denied,return to ship-do not fly over valley-stay over mountains-give film to so and so immediatly" or something very close to those words. After that transmission, I never heard that frequency used again.  The local radio station KIBS was talking about the UFO while it was overhead but when I called them after it was gone, they denied ever saying anything about it.
