Was that a couple F-16s flying over #Philly with afterburners on? I assume this has something to do with sports, and that they're not in a hurry to intercept a threat. Way too low and loud for my tastes.
@skyfaller it definitely felt much louder than the usual ones. I was about to turn on the TV to watch said sports game (I think it was military night) and still jumped out of my skin.
