Answer :

Final answer:

Following 9/11, new airport security measures including body scanners were implemented to enhance passenger safety.


Explanation:

New airport security measures included the use of body scanners as one way security procedures changed following the 9/11 terrorist attacks. In response to attempted attacks and to prevent future incidents, security measures at airports were significantly enhanced, leading to the introduction of body scanners to improve screening processes.

The introduction of body scanners was a direct response to specific incidents like the attempted bombing on a plane in 2009, resulting in tightened TSA regulations and increased scrutiny of passengers to ensure their safety.

These security enhancements, including body scanners, aimed to address the evolving threats faced by airports post-9/11 and have become crucial in maintaining passenger safety and preventing potential terrorist acts.
