class. I've got to go. Bye." Beamer told GTE phone operator Lisa Jefferson that he and a few passengers were getting together and were planning to "jump" the hijacker with the bomb. Beamer recited the Lord's Prayer and the 23rd Psalm with Jefferson, prompting others to join in. Beamer requested of Jefferson, "If I don't make it, please call my family and let them know how much I love them." After this, Jefferson heard muffled voices and Beamer answering, "Are you ready? Okay. Let's roll." These were Beamer's last words to Jefferson. During the hijacking, Flight 93 passed within (instead of the normal ) of a NASA KC-135 returning from a microgravity flight over Lake Ontario. NASA pilot Dominic Del Rosso recalled how odd the silence on the radio was that morning. Passenger revolt The passenger revolt on Flight93 began at 09:57, after the passengers voted on whether to act. The plane left its Washington, D.C. course after the passengers revolted and the hijackers began maneuvering the plane violently in response. The hijackers in the cockpit became aware of the revolt at 09:57:55, Jarrah exclaiming, "Is there something? A fight?" Edward Felt dialed 9-1-1 from his cell phone from the rear lavatory of the aircraft seeking information at 09:58. His call was answered by dispatcher John Shaw, and Felt was able to tell him about the hijacking before the call was disconnected. Multiple news reports (originally based on a 9-1-1 supervisor's account after having overheard the call) asserted that Edward Felt reported hearing an explosion and seeing smoke from an undetermined location on the plane. These reports were not corroborated by Shaw or Felt's wife, Sandra, who listened to the recording afterwards. CeeCee Lyles called her husband once more from a cell phone and told him the passengers were forcing their way into the cockpit. Jarrah began to roll the airplane left and right to knock the passengers off balance. He told another hijacker in the cockpit at 09:58:57, "They want to get in here. Hold, hold from the inside. Hold from the inside. Hold." Jarrah changed tactics at 09:59:52 and pitched the nose of the airplane up and down to disrupt the assault. The cockpit voice recorder captured the sounds of crashing, screaming, and the shattering of glass and plates. Three times in a period of five seconds there were shouts of pain or distress from a hijacker outside
