How One Small Step Became a Giant Leap

It was 45 years ago today, July 20, 1969, that a human being first stepped onto the moon’s surface. I remember it well, because I was one of the billion Earthlings who watched it happen, as TV broadcast images of Neil Armstrong stepping off the lander onto the lunar surface. Space reporter Jay Barbree covered the Apollo missions as they happened, and now has a biography of Armstrong called Neil Armstrong: A Life of Flight. Astronomy magazine has a five-page excerpt from the book in honor of the moon landing’s anniversary. Highlights include:  
 

Armstrong wasn’t sure what he would say when he stepped on the Moon: “For some time, he had been thinking about what he would say when he actually stepped on the Moon. He had thought about one statement he judged had meaning and fit the historic occasion, and he ran it by his brother, Dean, and others close. Neil had not made up his mind. He told me he was undecided until he was faced with the moment.”

What Armstrong thought about the Earth as he stepped on the moon: “In this neighborhood of the universe, it was life’s only world. It was encased in diamond-hard blackness, and Neil recognized it mattered little if we were Republican, Democrat, Independent, apolitical, Christian, Jew, Muslim, Hindu, or Buddhist, or who the hell we liked or disliked. We live on a vulnerable world where we must take care of its very finite resources — on a world where we all would suffer terrifying consequences if we drained it of its ability to sustain us — its ability to foster and nurture the very life we now threaten to contaminate.”

President Nixon’s words to Armstrong and Buzz Aldrin: “I just can’t tell you how proud we all are of what you are doing for every American. This has to be the proudest day of our lives. And for people all over the world, I am sure they, too, join with Americans in recognizing what an immense feat this is. Because of what you have done, the heavens have become a part of man’s world.”

@Jimbo the stopping distance is irrelevant. At that distance it's your reaction time that matters. If the truck's brakelights come on at that distance you've hit it before you could even squeeze the brake lever.

I recall some idiot trying to draught the bus I was on a few years ago. He probably wasn't even as close as this guy, the bus driver didn't even brake hard and the cyclist hit the back of the bus. Now he didn't hit it hard, but hard enough to take him down. Whereupon he slid under the rear of the bus. He lost a fair amount of skin, was battered and bruised and received minor burns from the exhaust, but he was lucky. Sliding under the back of a stopping bus is probably preferable to being run over by the following car.

And of course you should always remember that if you can't see the driver of the truck, he can't see you. So he won't be making any allowances for you.

Then there's the other problem with draughting too close. You can't see what the guy in front can see. I recall riding along once at speed when I swerved to miss a serious pothole, only to hear a clattering and swearing behind. A rider of whom I was completely unaware had been slipstreaming me and had hit the pothole good and hard. He lost skin and teeth. And all to take a little effort out of riding.

Back when I was young and stupid. I did this sort of thing with the whole bike racing team every once in a while. We mostly did it to freak people out seeing a line of 6-8 bikes go flying by you on the highway has a tendency to make them look. You can even draft cars. Which is a little safer since you can see whats ahead of the car.
Chances are the truck driver didn't even know the guy was behind him. They can't see most cars behind them let alone a bike rider.

Is it possible for an 18-wheeler to "brake all of the sudden"?
