Betty Ong, 45, of Andover: Flight attendant. Ong called her airline supervisor before the flight crashed to say she had seen at least three hijackers with weapons and some people had been stabbed. A day before the American flight, Ong made a return flight from San Jose to Boston with her co-worker, Kathy Glauser. "We just sat here and cried," said Glauser's husband, Matt.
