Is there a hole under the airplane that shoots the waste into the sky? Does it just magically disappear?Obviously they can’t drop it out – we would definitely know about it if that happened – but instead there’s a very effective system in place for disposing of all waste products.
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.
The waste is moved through the pipes, just like your home toilet system, but in this case, it is stored in tanks on board in the airplane as opposed to entering the sewage system.
Once the plane lands, the brilliantly named “honey truck” — a specially-designed vehicle that can hold 800 gallons of waste — arrives to take all that plane waste elsewhere.
