MOUNT PLEASANT, S.C. (WCBD) – The USS Yorktown honored victims of the September 11, 2001, terror attacks by sounding its horn Sunday morning.

The horn brought attention to the significant moments of that day 21 years ago.

The USS Yorktown will blasted its horn six times throughout the morning:

  • 8:46 a.m.
  • 9:03 a.m.
  • 9:37 a.m.
  • 9:59 a.m.
  • 10:03 a.m.
  • 10:28 a.m.
