If D-Day - the greatest amphibious operation ever undertaken - failed, there would be no going back to the drawing board for the Allies. Regrouping and attempting another massive invasion of German-occupied France even a few months later in 1944 wasn't an option.
— Douglas Brinkley
Usually, one day in a century rises above the others as an accepted turning point or historic milestone. It becomes the climactic day, or 'the day,' of that century.
What I was most curious about was why Armstrong, a top U.S. Navy test pilot, flying the most advanced aircraft in the world, would want to join the astronaut corps in 1962, which included chimpanzees and monkeys.
I was only 8 years old on July 20, 1969, when Neil Armstrong, 38-year-old commander of 'Apollo 11,' descended the cramped lunar module Eagle's ladder with hefty backpack and bulky spacesuit to become the first human on the moon.
Richard Kerry not only was a pilot in World War II, but was a civil servant. He did not come from money.
President Obama had a few historians at the White House for a couple of dinners. I was lucky enough to be one of those asked, and he was very interested in Ronald Reagan, and I came away feeling that.
Demeanor-wise, Reagan was a conservative, but a pragmatic conservative, and he found silver linings in things. He liked to be a mediator. He didn't like to have enemies around him.
John Kerry doesn't think in terms of black-and-white. He's all gray, and he looks at all sides of the issues. That makes people think he likes to be devil's advocate. Whatever you say, he'll challenge you on.
I feel like I'm always learning from people.
It is a long revisionist road up from the bottom for George W. Bush. He is ranked toward the bottom rung of presidents.
If you're a Kennedy and you go to Italy or you go to Argentina, you're treated as royalty. And in the United States, we're endlessly fascinated by the family.
The D-Day moniker wasn't invented for the Allied invasion. The same name had been attached to the date of every planned offensive of World War II. It was first coined during World War I, at the U.S. attack at the Battle of Saint-Mihiel, in France in 1918.
The Middle East is the tinder box of the world, and to be able to remove a nuclear threat of any kind out of Iran, that would have been a big deal, very positive step forward.
For years, I longed to hear Armstrong describe what it was like to contemplate Earth from 238,900 miles away. Former Space Center director George Abbey once told me that many NASA astronauts felt that looking at Earth was akin to a religious experience.
John Kerry had a very vivid imagination as a young person. I mean, he actually did go and take his bicycle from Norway to go camp in Sherwood Forest to be around the ghost of Robin Hood.
When we settled our country, the dark forest was considered in some ways evil and something that you needed to plow or, later, bulldoze. We now have a new understanding of the interconnectedness of ecosystems and the need for bird flyways and why all species matter.
Ever since Willie Nelson brought rednecks into an alliance with hippies back in the psychedelic '70s, Austin has milked its quirky libertarian spirit for a worldwide bonanza of free publicity.
John Kerry wants to be the hero in his own drama. He likes King Arthur and the Round Table. He likes the young swashbuckling Churchill, and he loved the early antics of Theodore Roosevelt.
John Kerry can be absolutely ruthless. I would not want to be on his enemies list when he's ready to go after you.
When I was 8 years old, I made my own encyclopedia of American biography - Johnny Appleseed, Jim Bowie, Davy Crockett, Daniel Boone, Charles Lindbergh, my pantheon of favorite heroes. Then I would write my own things and sew them together and try to make my own book.
I'm not a partisan.
We can only imagine the history of the free world today if, at the end of the Civil War, there had been two countries: the United States and the Confederate States of America.
Nobody has trusted the Iranian government from day one, but the idea of just refusing to have any kind of talks is dangerous in the extreme. Every administration says at least that we're trying to have talks between Israel and Palestine and solve the Middle East peace problem.
To Armstrong, constantly speaking about 'Apollo 11' only diminished the magic. That's why he worked overtime to avoid notice, living a quiet life in Indian Hill, Ohio.
John Kerry only went to prep schools because he had an aunt who had the money to pay for his way into those prep schools.
It's very important that we keep these special, wild places. It defines the United States. Imagine our country without our national parks and our monuments. Here in California, imagine if you didn't have in Southern Cal the Channel Islands or the great Highway 1, Big Sur up to Point Reyes up to the Redwood country.
Politicians wanted to mine the Grand Canyon for zinc and copper, and Theodore Roosevelt said, 'No.'
I think there's a green side to John Kerry, if you like, that he's an environmental activist. His record on the environment is as best as you have on a pro-environment record of anybody in the U.S. Senate.
I have a lot of books I want to write.
There is nobody that's ever going to fill Ted Kennedy's shoes, and that's a tall order for somebody in the family to try to live up to.
Animals interest me more than anything else.
