How is toilet waste disposed of on a plane?

In a plane toilet, strong suction and teflon-like walls pull excreta away using a small quantity of water. As you press the flush button, the vacuum at the bottom of the bowl sucks the waste into a holding tank. The waste is sucked into a tanker at the airport and then dumped.

Why do planes need to fly so high?

At high altitude, aircraft fuel burn is much less per mile travelled when compared to low level flight because of the reduced aerodynamic drag and improved jet engine efficiency. This means a jet aeroplane can fly much faster whilst using less fuel at a high altitude.

What would happen if you open an airplane door mid flight?

The door opening would cause a rapid decompression that would depressurize the plane cabin in a matter of seconds, causing a strong suction pull. This strong suction pull would cause all loose objects to be sucked outside the plane, including people who aren't buckled in.
