The September 11 attacks struck the nation on a clear, late summer morning on the East Coast. Hijackers used jet airliners as weapons and rammed them into New York City’s World Trade Center and the Pentagon. One hijacked plane crashed in a field outside Shanksville, Pennsylvania. In all, 2,977 were killed.
The 9/11 attacks not only became the single deadliest terrorist attack in human history, they were also the deadliest incident ever for firefighters, as well as for law enforcement officers in the United States.
As in years past, six moments of silence will be observed — to mark the times (8:46 a.m. and 9:03 a.m.) that each hijacked plane struck the North Tower and South Tower, to mark the times when each tower fell (9:59 a.m. and 10:28 a.m.), and to mark the moments of the attack on the Pentagon (9:37 a.m.) and the crash of hijacked United Airlines Flight 93 near Shanksville, Pa. (10:03 a.m.).
President Trump is scheduled to join an observance at the Pentagon, while Vice President Mike Pence is slated to speak at the annual remembrance ceremony at the Flight 93 National Memorial.
