The Wright Brothers by David McCoullough
Finished last night. It was quite a moment in history. Next time you're sitting on the tarmac, perhaps this holiday season on your way to visit your relations, you should take a moment to think about the Wright brothers, Wilbur and Orville. It should make you feel all warm and fuzzy inside. Reason is that people from prehistoric times have wanted to fly, quite a few tried and many died trying it, in all kinds of ways. Many Wright brother contemporaries were failing in their attempts, failing in spectacular ways (you've probably seen video clips of the ludicrous, comical contraptions).
It took a family affair to work it out. Strong father and mother, special relationship between Wilbur and Orville, and a ton of help from sister Katherine much of the time. Without that family factor, it wouldn't have happened. Some day it would have, but these guys started a huge technical revolution.
I recommend the book. It's very well researched and written, by two time Pulitzer Prize winner.
