Two hours later Welsh, who was Flight 93's first-class attendant, was stabbed to death by the hijackers. Horniacek likely was the final outsider the five flight attendants spoke with at any length before they boarded the San Francisco-bound plane.

On United Airlines Flight 93 during the September 11, 2001, terrorist attacks, five brave flight attendants were among those who lost their lives: Lorraine G. Bay, Sandra Bradshaw, Wanda Green, CeeCee Lyles, and Deborah Welsh. These individuals are remembered as heroes for their actions during the hijacking, as they provided critical information to ground controllers and assisted the passengers in the revolt against the terrorists, which ultimately prevented the aircraft from reaching its intended target in Washington, D.C. Sandra Bradshaw and CeeCee Lyles, in particular, are noted in historical records for making final phone calls to their families, during which they described the situation on board and mentioned that the crew and passengers were preparing to "force their way into the cockpit." At the Flight 93 National Memorial in Shanksville, Pennsylvania, their names are etched in stone alongside the pilots and passengers. In the context of 2026 aviation history, their legacy continues to influence airline safety protocols and the training given to cabin crews regarding onboard security threats and emergency communications.
