You can probably remember exactly what you were doing the moment the Twin Towers fell in New York 20 years ago.
The Halifax airport wants to help mark this milestone anniversary with a special ceremony on Saturday.
On September 11th, 2001, terrorists took control of four commercial flights in the United States.
Two of those planes were flown into the Twin Towers, forever altering the New York skyline.
Another hit the Pentagon in Virginia. The fourth plane didn’t strike its target because passengers and crew fought to regain control of the plane.
About 3,000 people were killed in what has been called the worst terror attack in history. It resulted in the complete shutdown of North American airspace.
Thousands of planes were forced to land immediately amid the tragedy.
That’s when our city stepped in to help. The Halifax airport received 40 aircraft carrying 8,000 passengers.
Staff dropped what they were doing to welcome the passengers, helping them over five days, until the flights were allowed to take to the skies again.
The Halifax airport helped the greatest number of flights, and it was amongst the first to have the diverted planes back in the air.
Halifax Stanfield says several officials will speak at the ceremony, which kicks off at 1 p.m. on Saturday.
