FOR MORE THAN A CENTURY NOW, aviators have been proving that the answer is "yes" to some of mankind's most audacious questions. In 1903: Can we develop a manned aircraft that will sustain powered flight? In 1927: Can we fly across the Atlantic Ocean nonstop? In 1947: Can we fly an airplane faster than the speed of sound?

Would a good old-fashioned challenge be enough of a reason to attempt the improbable?
