If You Fly, There Are Things That Only Exist Because of September 11th

Airports in the United States, but also around the world, changed dramatically after the September 11, 2001 attacks. Since then, various security measures have been implemented that previously did not exist or were not as rigorous. These changes profoundly affected the experience of flying, completely transforming the way passengers and luggage are checked at air terminals. Many of the restrictions and security procedures that are now considered normal in civil aviation are a direct result of the need to prevent new terrorist attacks.
