Neil Armstrong's friends, NASA colleagues and admirers around the country say the former astronaut was a humble pilot who served his country above all.
His shuttle colleagues Buzz Aldrin and Michael Collins said Saturday that they will miss a dedicated, smart and careful astronaut and friend.
In Washington, D.C., tourist Jonathon Lack from Alaska said he decided to tour the Air and Space Museum after hearing of Armstrong's death.
He says he sees in Armstrong's death a reminder of an America where people dreamed big things and sought to accomplish the inconceivable.
At the Armstrong Air and Space Museum in Ohio, a black ribbon hung over a plaque of Armstrong in the museum's entryway and a U.S. flag was lowered in Armstrong's memory.
