Low flyby of military planes this morning in Orange County

Two warplanes flew over my house this morning. Twice, unless there were two separate flights of them. I hid under a desk for the first flight as I thought the world was ending, but shortly after the second flight I took this picture of a much higher altitude plane that seemed to be associated with the low-fly group.



What is it? And what were the other planes? One friend suggests it was the Commemorative Air Force.
