Betty Ann Ong (simplified Chinese: 邓月薇; February 5, 1956 – September 11, 2001), born in San Francisco, was a Chinese American flight attendant onboard American Airlines Flight 11 when it was flown into the North Tower of the World Trade Center as part of the September 11, 2001 terrorist attacks.
Ong was born to Harry Ong Senior and Yee-gum Ong on February 5, 1956. She grew up in San Francisco's Chinatown and graduated from George Washington High School. Her family owned a grocery store on Jackson Street. Ong was the youngest of her surviving siblings: sisters, Cathie Ong Herrera, Gloria Ong Woo and brother Harry Ong.
Ong began her career as a flight attendant in 1987. Her professionalism and hard work later earned her the position of a purser, a head flight attendant.
On September 11, Ong assigned herself to Flight 11, so she could return to Los Angeles and go on vacation to Hawaii with her sister. During the hijacking, Ong called in to American Airlines emergency, she identified herself and alerted the supervisor that the aircraft had been hijacked. Along with fellow flight attendant, Madeline Amy Sweeney, she relayed seat numbers of the hijackers. During her 23-minute call, she reported that none of the crew could open the cockpit door, two flight attendants and a passenger had been injured and one of the hijackers had sprayed mace in the first class cabin.
