From the eternal flame at his gravesite to the historic Air Force One plane, many key items that make up the searing images from the assassination of President John F. Kennedy are available for public viewing 50 years later.

In some cases, officials had to scramble to make that happen.

The Boeing jetliner on which Lyndon B. Johnson took the oath of office is in a hangar near the National Museum of the U.S. Air Force near Dayton, Ohio. Federal budget cuts had halted shuttle buses to the hangar. But with the anniversary approaching, museum officials decided they had enough resources to resume tours on a trimmed schedule.

The eternal flame at Arlington National Cemetery in Virginia was restored recently. And the presidential library in Boston is preparing a special display.
