A local radio talk show got dozens of calls the other day about a fast-moving, greenish light near military aircraft. I don't know if anyone reported
it officially, but it sounds a lot like what was going on down in Needles. To hear the audio of the program, follow this link
www.robarnieanddawn.com..., then scroll down and select the audio files.
I haven't listened, but I have a pretty good idea what it's probably going to be from your description of the UFO being "green" (edit to add: and
fast moving).
