Bob had gotten his pilot's license and was very eager to start flying a real plane.
Frank agreed to let him borrow his friend's plane, and he took to it right away.
He flew all across the country, taking in the sights, snapping photos every which way. It was heaven.
Until he decided to take a shortcut through DC and ended up close to the White House.
He was commanded to turn around, but he refused, insisting he wasn't going to hurt anyone by flying over.
He was then shot down from the sky, dying instantly. And the only proof left of his short lived flying adventure was the photos he sent back home digitally.
