One small (mis)step for NASA.

In case you lose things in your office, you're in good company. It happens to our friends at NASA, too. Of course, you probably don't keep original copies of the Magna Carta sitting around in your office...

WASHINGTON (Reuters) -- The U.S. government has misplaced the original recording of the first moon landing, including astronaut Neil Armstrong's famous "one small step for man, one giant leap for mankind," a NASA spokesman said on Monday.

Armstrong's famous space walk, seen by millions of viewers on July 20, 1969, is among transmissions that NASA has failed to turn up in a year of searching, spokesman Grey Hautaloma said.

"We haven't seen them for quite a while. We've been looking for over a year and they haven't turned up," Hautaloma said.
