CINCINNATI (AP) — Neil Armstrong was a soft-spoken engineer who became a global hero when as a steely-nerved pilot he made "one giant leap for mankind" with a small step onto the moon. The modest man, who had people on Earth entranced and awed from almost a quarter-million miles away, but credited others for the feat, died Saturday. He was 82.
Armstrong died following complications resulting from cardiovascular procedures, his family said in a statement. Armstrong had had a bypass operation this month, according to NASA. His family didn't say where he died; he had lived in suburban Cincinnati.
Armstrong commanded the Apollo 11 spacecraft that landed on the moon July 20, 1969, capping the most daring of the 20th century's scientific expeditions. His first words after becoming the first person to set foot on the surface are etched in history books and the memories of those who heard them in a live broadcast.
"That's one small step for man, one giant leap for mankind," Armstrong said.
(Armstrong insisted later that he had said "a'' before man, but said he, too, couldn't hear it in the version that went to the world.)
In those first few moments on the moon, during the climax of a heated space race with the Soviet Union, Armstrong stopped in what he called "a tender moment" and left a patch to commemorate NASA astronauts and Soviet cosmonauts who had died in action.
"It was special and memorable but it was only instantaneous because there was work to do," Armstrong told an Australian television interviewer this year.
Armstrong and Buzz Aldrin spent nearly three hours walking on the lunar surface, collecting samples, conducting experiments and taking photographs.
"The sights were simply magnificent, beyond any visual experience that I had ever been exposed to," Armstrong once said.
The moonwalk marked America's victory in the Cold War space race that began Oct. 4, 1957, with the launch of the Soviet Union's Sputnik 1, a 184-pound satellite that sent shock waves around the world.
Although he had been a Navy fighter pilot, a test pilot for NASA's forerunner and an astronaut, Armstrong never allowed himself to be caught up in the celebrity and glamour of the space program.
"I am, and ever will be, a white socks, pocket protector, nerdy engineer," he said in 2000 in one of his rare public appearances. "And I take a substantial amount of pride in the accomplishments of my profession."
Fellow Ohioan and astronaut John Glenn, one of Armstrong's closest friends, recalled Saturday how Armstrong was down to the last 15 seconds to 35 seconds of fuel when he finally brought the Eagle down on the Sea of Tranquility.
"That showed a dedication to what he was doing that was admirable," Glenn said.
A man who kept away from cameras, Armstrong went public in 2010 with his concerns about President Barack Obama's space policy that shifted attention away from a return to the moon and emphasized private companies developing spaceships. He testified before Congress, and in an email to The Associated Press, Armstrong said he had "substantial reservations," and along with more than two dozen Apollo-era veterans, he signed a letter calling the plan a "misguided proposal that forces NASA out of human space operations for the foreseeable future."
Armstrong was among the greatest of American heroes, Obama said in a statement.
"When he and his fellow crew members lifted off aboard Apollo 11 in 1969, they carried with them the aspirations of an entire nation. They set out to show the world that the American spirit can see beyond what seems unimaginable — that with enough drive and ingenuity, anything is possible," Obama said.
Obama's Republican opponent Mitt Romney echoed those sentiments, calling Armstrong an American hero whose passion for space, science and discovery will inspire him for the rest of his life.
"With courage unmeasured and unbounded love for his country, he walked where man had never walked before. The moon will miss its first son of earth," Romney said.
