San Francisco's annualFleet Week, starts this Thursday, so don't be surprised if you see fighter jets flying overhead or a general roar coming from the sky.
During Fleet Week, the Blue Angels of the U.S. Navy and other pilots will be performing daring acrobatic air shows in the skies over the city. You can catch a glimpse from pretty much anywhere in San Francisco, but for ideal views of the air show, head down to waterfront near Pier 39 and the Marina Green between 1 and 4 p.m. on Saturday or Sunday. Reserved seating is also available, from $25.
Military vessels will also be open for public viewing over the weekend, including the massive USS Pinckney, a guided-missile destroyer on Pier 35. The Canadian Navy will also have ships participating, for good reason—2010 marks their 100th anniversary.
October 7-12, dates and times vary. See full schedule here.
