Todd Beamer, a passenger on the hijacked United Airlines Flight 93 on 9/11, tried to place a credit card call through a phone located on the back of a plane seat but was routed to a customer-service representative instead, who passed him on to supervisor Lisa Jefferson. Beamer reported that one passenger was killed and, later, that a flight attendant had told him the pilot and co-pilot had been forced from the cockpit and may have been wounded. He was also on the phone when the plane made its turn in a southeasterly direction, a move that had him briefly panicking. Later, he told the operator that some of the plane's passengers were planning to attack the hijackers and take control of the aircraft. According to Jefferson, Beamer's last audible words were "Are you guys ready? Let's roll."
In November 2001, Neil Young released a song about Beamer and Flight 93 called "Let's Roll." The song was later released on his album Are You Passionate?.
