Suppose you are going in jet plane and one of the windows breaks due to an accident what problem do you think you will have?

Answer 1

The plane will undergo explosive decompression as the air pressure inside the plane is much higher than the air pressure outside.

Now, before we go any further - explosive decompression does not mean the plane will explode. It means that the plane decompresses faster than your lungs are able to cope so the air 'explodes' out of your lungs. Your lungs would be injured due to the force generated by air leaving very quickly.

The air inside the plane will be sucked out until the air pressure equalizes. Because there will consequently be very little air left in the plane you would of course need an oxygen mask to breathe.

Contrary to popular belief, if the window breaks, neither you, the chair you're sat on, or your baggage, would be sucked out of a small hole (like the window). The fuselage design of the plane prevents this from happening (see Mythbusters, where several tests were undertaken with high-pressure aircraft which were shot).

However, if there was an extremely large hole (like the cargo door coming off) then it is plausible for people to be sucked out (passengers have been torn out of planes where this has occurred - but this usually occurs as a result of the damage - which usually takes the seats with it).

On an unrelated subject, a person would not explode either due to the decompression, human skin is strong enough to withstand a drop of one atmosphere in pressure. You might swell up a bit, but that's it.

Your nerves would not explode - and the pressure high above sea level is actually lower, not higher. Pressure increases as you get closer to the Earth's core - e.g. water boils at 280 degrees centigrade a few kilometres under the Earth's surface (this is a fact that geothermal power stations exploit) but it only requires 75 degrees centigrade to boil at the top of Mt Everest.

Planes don't artifically generate pressure; the air pressure inside the plane is the same as the air pressure where the plane took off from (as it is filled with air from this location which is constantly recirculated, temperature adjusted, cleaned etc by air conditioning). Once the plane doors are properly closed the plane is airtight.
