Thousands more gathered today in Shanksville, Pennsylvania to honor the 40 passengers and crew killed aboard Flight 93.
For the second day in a row, thousands gathered at the crash site in Shanksville.
The Associated Press reports visitors at Sunday’s memorial service observed moments of silence at 8:46 a.m. and 9:03 a.m. – the times when two other airliners crashed into New York’s twin towers.
According to the AP, President Obama was scheduled to visit the Flight 93 site, but it wasn’t clear if he was going to speak during the ceremony. The President is expected to lay a wreath at the memorial following the ceremony and meet with family members of the victims.
On Saturday, former presidents Bill Clinton and George W. Bush, along with Vice President Biden and several other political figures attended the tribute.
