Everyone remembers where they were on the morning of September 11, 2001. The tragic events of that day lead to the cancellation of sporting events, closure of national landmarks, and a three-day ground stop of all civilian aircraft in the US. Similar precautions were taken around the globe.
Thankfully, yet solemnly, we were soon returning to work and life slowly began to normalize.

Over time, we’ve come to accept this as the new normal.
