Well, some more info has come to light.
The person who posted the picture on the nextdoor app has clarified that the picture he posted was "for reference only", it was NOT taken recently or in the bay area and is a stock image downloaded from the web.
So disregard the Airbus, I suspect it was taken many years ago.
So I assume these folks saw a 135 from Travis however in the 9 years I have lived in the area I have never seen a refueller down low, especially with several fast jets in tow?
Cheers for now.
