I don't know who John D. Duvall is, but look at this poem he wrote:
To All That Fly
May God grant you blue skies aloft,
With winds of calm by land,
As you play on the outskirts of heaven,
On the fragile wings of man.
His little verse is particularly apt today, the anniversary of the birth, in 1867, of Wilbur Wright. Moreover, exactly 100 years ago today, on the 16th of April, 1912, pioneer aviator Harriet Quimby became the first female pilot to fly, alone, in a tiny dragonfly of an 'aeroplane' across the stormy English Channel.
“Without any of the modern instruments, in a plane which was hardly more than a winged skeleton with a motor, and one, furthermore, with which she was totally unfamiliar, to cross the Channel in 1912 required more bravery and skill than to cross the Atlantic today." Amelia Earhart, 1928
