I think I heard the same air traffic last night on LAFB Tower 124.3000 ,,,, about that same time frame.
I think I recall hearing the pilot say to the tower that "I will be out of your airspace very soon", etc.
Didn't catch anymore than that ... but lots of Air to Air Helo Chat on 123.0250 between what sounded
like the News Helicopters or perhaps between Media-1 (Sky5+Sky12) and the SAPD Eagle Helo ?
