I was flying SFO-LAX-DEN this past 9/11. The SFO-LAX leg was uneventful, no sort of announcements from the crew; just another day.
LAX-DEN, however, was different. We boarded the plane (IPTE 772) and before I knew it, were in the air. The purser came on the intercom, and instead of discussing the services of the flight, stated she wanted to commemorate the day. She then proceded to give one of the most eloquent speeches about a colleague and close friend she lost on 9/11 on flight 93. By the end of the 3-minute speech, her voice started to crack, and she started to choke up. She ended it by saying "we are all United", which pay sound cheesy here on this forum, but was powerful onboard. Lots of people around me started to loose their composure as well, I know I did. It was a beautiful tribute to her friend.
