MODELING REAL LIFE In 2003, a remote-controlled model airplane became the first ever to fly nonstop across the Atlantic Ocean. The map shows the airplane's position at three different points during its flight. Point A represents Cape Spear, Newfoundland, point B represents the approximate position after I day, and point C represents Mannin Bay, Ireland. The airplane left from Cape Spear and landed in Mannin Bay.
