The skies above San Francisco just got a little quieter. According to SFAppeal/BCN, "Heavy fog in San Francisco caused the cancellation of today's Blue Angels air show, a spokeswoman for Fleet Week said." The show was scheduled to start at 3 p.m.

The Blue Angels, it seems, "are not allowed to be flown in air shows when fog has settled below 1,500 feet."

Sunday's jet show is still planned for 3 p..m -- unless, of course, fog intervenes again.
