While I was driving around today, I heard a couple of very loud BOOMs. Turns out President Obama was in Seattle pimping for Senator Patty Murray and a seaplane breached the restricted airspace around the area. A couple of F-15s scrambled to the area, causing a sonic boom that was heard all over the Puget Sound. People were talking about it in Gig Harbor, that's for sure, though at that point, nobody really knew. Twitter eventually got the story out.
Meanwhile, some enterprising fellow already created t-shirts celebrating the sonic booms.
