I'm remembering it happening earlier as well. I always assumed this 2001 incident immediately prompted the policy. https://en.m.wikipedia.org/wiki/American_Air

  I got into this debate with someone else. That was the Flight that prompted the policy but TSA itself wasn't fully implemented for another 3-6 years because it worked at the speed of bureaucracy and security theater and equipment upgrades. There were partial rollouts, some airports were way faster than others at things like "take off your shoes and send them through the luggage scanner". But some of that wasn't even under the banner of TSA. TSA was a weird rollout.
