Guns in Airplanes

Well, I think if someone fired a gun, they would land immediatly anyway. Besides, if the bullet dosen't get stuck in someone (Which would be pretty obvious) then it has most probably made it's way outside.

I used the believe that you would be sucked out of the plane, like Auric Goldfinger did in Goldfinger. After watching Mythbusters, I know different.

What I found totally surprising was when they blew out the window, the only thing that was sucked out were very small items.

There is a key factor missing from the Mythbusters' experiment. They performed the test at ground level. Most explosive decompression happen high up in the air where the atmospheric pressure is lower on the outside as compare to the inside. The difference in atmospheric pressure is the key factor in determining rather or not a window will explode if it is damaged by a bullet or other projectile. We know air pressure will seek an equilibrium moving from Point A to Point B. If the air pressure is less in Point B rather than Point A, it will seek this equilibrium point of balance.

I am not an avionic engineer so I don't know much about the actual figures and physics involved. However if we take this to avionic experts I think they will agree with this assessment and point out the Mythbusters' errors.

EDIT - Here is an article on explosive decompression and its effects. Check it out. :ermm:

The Mythbuster's took that into account.

The difference in air pressure is less than 10 PSI. Definitely not enough to make for explosive decompression. Even in space you will likely NOT see explosive decompression, just a faster leak.

Yep , it was on Mythbusters several weeks ago (here) , and very interesting too.

10/14 ATM (0.71 ATM) if cruising at 40,000 ft.

So in your opinion, a hole in a window, even in space, will only cause a faster leak? What if a heavy object shatter the window? Wouldn't this create explosive decompression? :shrug: :headscratch:

There has to be a high pressure gradient to create "explosive decompression." What you see in movies and the like simply does not happen in physical reality, just like bodies being exposed to vacuum. <-- in this case, while you may feel icepicks in your ears and your eyelids might freeze open because the moisture on your eyes boils off, you don't blow up and explode.
