The passenger revolt on Flight 93 began at 09:57, after the passengers took a vote amongst themselves about whether to act.^[23] By this time, Flight 77 had struck the Pentagon and Flights 11 and 175 had struck the World Trade Center towers. As the revolt began and the hijackers started maneuvering the plane around violently, the plane went off of its Washington, D.C. course.^[23] The hijackers in the cockpit became aware of the revolt at 09:57:55, exclaiming, "Is there something? A fight?"^[35]

Edward Felt dialed 9-1-1 from his cell phone from the lavatory of the aircraft seeking information.^[33] His call was answered by dispatcher John Shaw, and Felt was able to tell him about the hijacking before the call was disconnected.^[53] There were reports of Felt's hearing an explosion and seeing smoke coming into the lavatory from under the door.^[54] These reports were not corroborated by Shaw, the 9-1-1 transcript, or Felt's wife, Sandra, who listened to the recording afterwards.^[55]

CeeCee Lyles called her husband once more from a cell phone and told him the passengers were forcing their way into the cockpit.^[21] Jarrah began to roll the airplane left and right to knock the passengers off balance. He told another hijacker in the cockpit at 9:58:57, "They want to get in here. Hold, hold from the inside. Hold from the inside. Hold."^[35] Jarrah changed tactics at 9:59:52, exactly when the South Tower began to collapse, and pitched the nose of the airplane up and down to disrupt the assault.^[23]
