Today, the USS New York, which was partly made from World Trade Center steel, will be officially commissioned as a naval warship today and besides the military flyover, there's also going to be a cannon firing repeatedly: "During the Commissioning of the USS New York at Pier 86 & 88 in Manhattan on 11/7/09 at approx. 11 AM, the Sewell's Point Weapons Detachment will fire a cannon in honor of the senior officials attending the ceremony. You may hear 19 consecutive loud bangs at this time." The ship will be open to visitors tomorrow, Monday and Tuesday.
