No, aircraft don't dump waste at high elevations - or at all. They have holding tanks which contain waste until the ship is on the ground where ground crews can pump them down. (You can often see the service trucks that do this from the concourse of many airports.) It's SOP for the airlines. There have been incidents of some waste falling from altitude onto populated areas, but they are rare. The airlines are good about keeping things tidy. Even though it costs a bit of money to do this kind of maintenance, it is worth it to avoid complaints or law suits from citizens who get "bombed" with waste. It is also against regulations to dump waste, or even throw "stuff" out of an aircraft. The FAA could levy fines that would make the cost of waste management on an aircraft look like pocket change.
It is called fall line.
Because gravity gives objects at high elevations the potential to fall much further.
weathering occurs faster at high elevations because
When flying at hight altitudes (+12,000FT) planes pressurize the cabin so passengers can stay conscious without wearing oxygen masks.
