Aeroplane means a vehicle with wings which flies through the air.
If the crew cabin were not pressurized, it would still be full of air, except that the air would be at the same pressure as the air outside. Only if the craft is actually in outer space would there be no air outside. In the case of an airplane, there has to be air outside in order for the airplane to fly, but that does not mean that there is enough air to breathe. Pressurizing the cabin means that the air is at a sufficient pressure to be breathable.
They are called flight attendants (also cabin crew, stewards/stewardesses, air hosts/hostesses and cabin attendants)
this means that the air outside the aeroplane is too thin for us to breathe and the air has to be pressurised in the aeroplane. that is why the aeroplane has masks above your seat so if the air becomes to thin the air coming through the mask is the right for you to breathe.
It is because an aeroplane's cabin is pressurized, meaning that it is sealed off from the atmosphere. This prevents air escaping and keeps the pressure constant.
uh, it's an cabin AIR FILTER... it FILTERS the AIR in the cabin!!!
