At sunrise this morning, the American flag was unfurled at the Pentagon to commemorate the 16th anniversary of the September 11th attacks.
Nearly 3,000 people were killed when terrorists slammed hijacked planes into the World Trade Center, the Pentagon and a field near Shanksville, Pennsylvania, on September 11, 2001. 184 lives were lost at the Pentagon.
The day after the attack, firefighters draped an American flag over the gaping hole in the Pentagon that was left behind.
On every 9/11 anniversary since, the stars and stripes are unfurled on the side of the building damaged in the attacks to remember those who lost their lives there.
President Donald Trump and First Lady Melania Trump are scheduled to participate in a 9/11 observance at the Pentagon Memorial later this morning. They will be joined by Defense Secretary Jim Mattis and Gen. Joseph Dunford, chairman of the Joint Chiefs of Staff.
Vice President Mike Pence and U.S. Secretary of the Interior Ryan Zinke are scheduled to speak during a ceremony at the Flight 93 National Memorial near Shanksville.
