I locked out KFLL frequencies irrelevant to this event as the aircraft taxied. Congrats to the FLL ATC Controllers for showing and voicing their respect as Capt Sully taxied his A321. First, they taxied the aircraft around all traffic to the head of the line. Finally, as he made it short of the departure runway, one of the controllers read a farewell message. After departure the aircraft on freq joined in. Well done!
