Memorials are being held across the country today to mark the fifth anniversary of 9/11. In New York, moments of silence are planned at the World Trade Center site at the times when jetliners struck each of the twin towers and when each tower fell. Spouses and partners of the two thousand seven hundred and forty nine who died at the trade center are planning to read the names of each victim. Last night, lights filled the sky in Washington DC. The light display was made up of 184 beams, each one representing a life lost at the Pentagon. President Bush visited ground zero on Sunday. Today he is planning to visit the Pentagon and Shanksville, Pennsylvania where 40 people were killed when a jet crashed into the ground. The president is scheduled to address the nation tonight.
