So passengers will feel more comfortable. Higher interior pressure means more economical altitude.
no your gonna die
at ground level
Because at altitudes above 10,000 feet there is not enough air for humans to breathe. Aircraft cabins are pressurised so that the internal pressure is equal to that at about 7,000 feet.
If it wasn't pressurised there would be no air and the astronauts would die. Of course they could keep their spacesuits on but that would not be comfortable for an extended period of time.
cabins
The math behind aircrafts is very complex gemoetry and physics.
In a pressurised nuclear reactor the temperature is very high, which cn be accepted as a point for this.
There are about 312000 aircraft's in the world and out of them 17700 are passenger carrier aircrafts
It held 840 cabins.
Big Bear Cool Cabins offers many sorts of cabin accommodations including 1-5 bedroom cabins, pet friendly cabins, and lodges. Their website provides a list of available cabins.
As aeroplanes fly high in the atmosphere, where the air is thin, the inside has to be pressurised to allow the passengers and crew to breath.
in valley forge there are about 2,000 cabins
