Full Upright and Locked Position but it's a great read. One point - which was new to me - was how the pressurized system that removes waste from the toilet is so strong that there is frequently airborne waste (finer than mist) in the air after flushing. It also touches on how awful onboard water is - especialy on international planes. Defiantly don't put your mouth on one of those dixie cups

A standard toilet, at surface level, generates an aerosol of the bowl contents. I have imaged this at MIT and posted the images here but they were moved to the "Lets eat" thread.
