How Airplanes and Airport Workers Deal With Waste From the Onboard Toilets

A clip from X-Ray Mega Airport on Smithsonian Channel shows how airplanes and airport workers deal with waste from the onboard toilets. The advanced design of modern airplane toilets eliminates the need for large quantities of sanitation fluid that frequently leaked from older planes, but they still need to be emptied once a plane lands.

Modern airplane toilet bowls rely on strong suction and teflon-coated walls to flush–causing waste to accelerate through its pipes faster than a Formula One race car.
