*(Via Yahoo News) – President Barack Obama and First Lady Michelle Obama, placed a wreath at the Flight 93 National Memorial on Sunday, arriving at the site to pay respects to the 40 passengers and crew who died a decade ago Sunday.

The president and first lady visited the Wall of Names. Each of the 40 marble slabs is inscribed with the name of someone killed in the crash of United Flight 93 on Sept. 11, 2001.

Some 3,000 people, including thousands of regular citizens, were gathered at the Flight 93 memorial as Obama walked to a security barricade to shake hands. Others took his photo and sections of the crowd chanted “USA! USA!”

One man called out: “Thanks for getting bin Laden!” a reference to the death of Osama bin Laden, killed by U.S. forces in Pakistan earlier this year.

Jaleel Dyson, 18, came to the memorial to honor the victims but was excited to shake the president’s hand and get a picture of him on his smartphone.

Dyson, who is from Washington, D.C., but attends college in the area, said he also attended the president’s inauguration in January 2009. He said the 10th anniversary of the terrorist attacks was more important.

“I think it’s just important that the president shows his support for the families that lost loved ones,” he said.
