8:20 a.m.
Family members of those lost on Sept. 11 are arriving at ground zero for the ceremony marking the 15th anniversary of the attacks.
Some are going into National September 11 Museum, which is open only to victims’ families until Sunday afternoon, when the public will be allowed to enter.
About an hour before the official commemoration start, police officers in uniform and bagpipers rehearsed part of the ceremony involving a display of the US flag.
