11. The toilets are actually vacuums
Unlike your toilet at home that siphons water down into the sewer, airplane toilets are basically vacuums: a valve opens when you flush, and the air pressure sucks what’s in the bowl down into a tank located in the tail of the plane. It uses about half a gallon of water and can flush in any direction. But older planes with outdated toilet systems are still up there flying, hence the occasional reports of raw frozen sewage falling from the sky.
12. The wingspan of an Airbus is double the length of the original flight
Wilbur and Orville Wright’s first venture into the skies in 1903 traveled only about 125 feet. Today, the wingspan of the largest commercial airliner, the Airbus380, is 262 feet.
13. The average Boeing 747 has around 150-175 miles of wiring inside it...
That’s almost enough to stretch across Massachusetts. Beyond the wiring, it also has 6 million parts.
14. ... and is more fuel efficient than a hybrid
A Boeing 747 gets 0.2 miles per gallon, burning through 36,000 gallons of fuel over a 10-hour flight. Gas guzzling at its worst, right? Well, no. Do the math: With 500 people aboard that’s 0.01 gallons per person per mile, or 100 miles per gallon. Suck it, Prius.
