PRESSURE
Jeremy Berke
1 Commercial airplane cabins are generally pressurized to
an equivalent of 6,000 to 8,000 feet above sea level, in an
effort to maintain a healthy oxygen level for both the
passengers and the flight crew. When a passenger jet is flying
5 at a cruising altitude of over 36,000 feet, the pressure outside
the cabin is_____________ than inside the pressurized cabin.
Air pressure has a tendency to equalize, moving from areas
of high pressure to low pressure to achieve equilibrium.
When a hole rips open on a plane, the suction resulting from
10 the pressure difference between the cabin and the sky could
pull nearby people or objects outside. Depending on the size
of the hole, such accidents could either create just enough
force to shuffle papers around, or, pull a full-size human out
of the plane. Survival is unlikely for anyone fully sucked out
15 into the sky.
While in-flight incidents are extremely rare, if you want
to survive a crash, research suggests the best place to sit is in
a middle seat toward the back of the plane.
