Passengers on United Airlines flight 93 had voted to overpower hijackers after realising that the plane was to crash into the White House.

Jeremy Glick, a passenger on the plane which crashed in Pittsburgh, had been in contact with his wife by phone.

He said that the men on the plane had taken the vote after they had heard about the World Trade Centre crashes.

His two-month-old daughter, Emerson, was with him on the plane.

Moments later the plane crashed in Somerset County, Pittsburgh.
