Boeing 737 Facts
"10,000 737s stacked on top of one another would be approximately 406,000 feet or 77 miles (124 kilometers) high, and is equivalent to: 149 Burj Khalifa in Dubai, the tallest building in the world, stacked on top of one another; 274 Petronas Twin Towers in Kuala Lumpur, Malaysia; 382 Eiffel Towers, Paris; [and] 280 Empire State Buildings, New York City."

Wing Design
"Before a wing is designed, its mission has to be determined. What type of aircraft will this wing be attached to? Will it need to operate at high altitudes with thin atmospheres? Will it have to carry heavy loads? Will it need space to mount the engines? How much fuel will we want to store inside? How (Photo courtesy of Boeing) fast or agile will the aircraft need to be? The list of potential specifications is long and highly complex."

How Things Work: Winglets
"Winglets reduce wingtip vortices, the twin tornados formed by the difference between the pressure on the upper surface of an airplane's wing and that on the lower surface. High pressure on the lower surface creates a natural airflow that makes its way to the wingtip and curls upward around it. When flow around the wingtips streams out behind the airplane, a vortex is formed. These twisters represent an energy loss and are strong enough to flip airplanes that blunder into them."
