9:35 am: United Flight 93 goes off course near Cleveland, Ohio and turns for Washington D.C.

9:45 am to 9:58 am: Passengers on United Flight 93 begin calling family and emergency lines on their cell phones. During these conversations, they learn what has happened at the World Trade Center and Pentagon and realize that their plane is likely headed for a similar target in Washington D.C.

Todd Beamer, while attempting to call his wife, is patched through to a Verizon supervisor.    He tells what is happening on-board the plane and that the passengers have decided to fight the hi-jackers in an attempt to prevent the plane from hitting a target on the ground.  The last thing the Verizon supervisor hears is "Are you guys ready? Let's roll."

At 9:58 am, the passengers storm the cockpit and begin the confrontation with the             hi-jackers.  In the struggle, the plane veers over Pennsylvania.

9:59 am: As people begin to flee from the city, they watch in disbelief as the South Tower collapses, sending a massive cloud of smoke, dust and debris through the streets of Manhattan.
