Changes:
- "Whenever a rapid decompression is faster than the inherent capability of the lungs to decompress"
This just doesn't happen on commercial jets, although maybe it's a problem for astronauts. When the pressure drops, you will exhale no matter how hard you try to keep it in. Sentence deleted.
- "When temperatures drop because of a decompression, injuries such as frostbite and hypothermia will begin to appear. "
If the reduced pressure after a decompression for hypothermia to set in, you're already dead. Sentence deleted.
- "Cabin pressurization has additional benefits - for instance, the air-tight environment partially protects passengers from the tremendous noise of the engines and cold temperatures in high altitudes."
Not really true: Pressurized aircraft are definitely not airtight, noise protection comes from the walls, and pressure does not protect from cold. Sentence deleted.
Mythbusters
Mythbusters tested this myth in their usual semi-scientific ways. Their findings are in no way proof.
"Semi-scientific" is too polite a term. "Mythbusters" uses methodologies and criteria for the public that are often outright contradictory to science (I can't watch it). Rapid decompression is a dependent on the size of the hole as well as the volume and pressure of the cabin - and the delta pressure (altitude). It can be calculated, but one can't make an absolute statement because pressure,cabin volumes, delta pressure (and window areas) are not uniform.
First aircraft
Some people think that the Lockheed XC-35 was the first, and not the Boeing 307; However the first did not enter production.

Difference between cabin and cargo
Does anyone know what the difference between the pressure in the cabin relative to the cargo area is? How much pressure is your luggage subjected to (if the pressure in the cabin is 0.7 bar? When does spray bottles break?

- My uncle (a retired airline pilot) said that the cargo area is pressurized exactly the same as the cabin since they often carry pets down there. In newer planes it is even heated and uses the same ventilation system as the regular cabin.-- Nick. 08:49, 21 September 2007 EST. —Preceding unsigned comment added by 65.112.23.131 (talk)
