Don't know anything, Dave. I didn't hear anything last night and I sleep pretty light and bedroom window was open. San Diego is a pretty big place though and we have the USN over in Coronado and USMC in Miramar, both have jet runways and both are quite a distance from me. The article never said EXACTLY WHERE the siren was heard . . . could be anyplace. I'll keep my eyes and ears peeled.
It isn't in the local news here either so I'm gonna be skeptical at this point, but alert none the less.
!! FOXTROT JULIET BRAVO !!
