I guess it depends on whether it's sealed or not.
If it's open to the atmosphere how can it be under pressure ?
If it's sealed it could be put under (positive or negative) pressure so would be, by definition, a pressure vessel IMHO.
The liquids and solids go into a holding tank and are pumped out when the plane is on the ground, usually while the plane is refueling.
how can methanol be stored at above ground storage tanks
Ground tissue system
ground tissue
When a man stands on the ground his weight (force) is spread over a small area, causing high pressure on the ground (pressure is force divided by area). When a man lies on the ground his same weight (force) is spread over a larger area, causing low pressure on the ground (pressure is force divided by area).
You can't charge an object while holding it because you are grounding it by touching it. You ground it because a person is a conductor and they are conected to the ground, or earth.

someone holding your feet. if your feet are not being held they will move every time you get up Someone holding your feet will make the exercise FAR easier (and therefore less effective) than you having to use your muscles to 'hold' your feet in the ground and stop them from coming off the ground. In short start off with someone holding your feet, but progress when you have enough strength to using your core strength to fix them to the ground without anyone holding them.
Poorly constructed maintained or operated stations can pollute the environment by: * Releasing hydrocarbon vapors from the filling lines or product storage tanks to the air * Allowing cars to idel while filling * From losses of gasoline or diesel to the ground on nozzle withdrall * From leaking storage tanks to the ground or groundwater * From chemical spills (ethylene glycol or sulfuric acid) * From oil spills from holding tanks or poorly drained oil containers
