For many, if you ask them what they were doing on September 11, 2001, they can tell you in perfect detail, no matter how young or old they are. For many Americans, their lives changed with the terror attacks in New York City and Washington, D.C. For the rest of the world, these attacks changed airport security, tightening up restrictions that had become lax over time.

In fact, you can almost time it to the minute it happened. As soon as the planes hit, airports were shut down, and when they were re-opened, flying would never be the same again. So what time did the planes hit on 9/11? And what happened next?

There were four different planes that hit between 8:46 a.m. Eastern Standard Time and 10:03 a.m. Eastern Standard Time. They hit various locations in New York City, Washington D.C., and Pennsylvania in a series of planned terrorist attacks.

Key Takeaways

World Trade Center

Two planes hit the World Trade Center on September 11. 2001. The first plane, American Airlines flight 11, hit the North Tower at 8:46 a.m. At that time, no one knew what was coming, and many watched this horrible event unfold live on television. The second plane, United Airlines Flight 175, hit the South Tower at 9:03 a.m. At this point, it was clear that it was a terrorist attack.

Pentagon

The third plane hit the Pentagon, which houses the U.S. Department of Defense, in Washington, D.C., at 9:37 a.m. This was American Airlines 77, and part of the building collapsed as a result.

Shanksville, Pennsylvania

What Time Did the Planes Hit on 911

There was a fourth plane that was part of the September 11 terrorist attacks; however, no one knows what its final destination was. The plane crashed in a field near Shanksville, Pennsylvania when the passengers overtook the terrorists. There were no survivors.

What Happened Next?

At the end of the day, 19 hijackers took the lives of nearly 3,000 people that day, whether on the planes or in the buildings they attacked. So many more perished as a result of the attacks, including many who heroically rushed into the towers to try to save lives.

In the immediate aftermath, flights were grounded to prevent potential terrorist attacks, and when the airports re-opened, strict security protocols were in place. Now, you have to pass through security checkpoints and get scanned for potential concealed weapons. We take off our shoes, remove electronics from our bags, and pass our belongings to get x-rayed.

Additionally, now, we can only carry 100 ml or less of single-use liquids that fit in a 1 litre bag in our carry-on bags. It’s easy to grumble about these restrictions, but once you remember why they’re in place, they feel like the least you can do.

September 11, 2001, is a day that many will never forget, and its legacy lives on each day as we consider the impact it had on flying.
