And that would be this one?

A buddy of mine in Special Forces serving in Afghanistan once told me, "this is the absolute best sound in the world."

When you're in a tight spot, and you can call on this thing to make it all alright, I guess it would be.

#2 I can imagine it brings relief, but not when the bullets hit close to you http://www.youtube.com/watch?v=ZAkzrxN5Jn0

AHA!....sometimes also known as "Puff the magic dragon" :-)

From 3/4 of a mile!
Accuracy: 80% of rounds fired at 4,000 feet (1,200 m) range hit within a 40 feet (12 m) diameter circle
Ammo:
PGU-14/B API Armor Piercing Incendiary (DU)
PGU-13/B HEI High explosive incendiary
Armor penetration:
69 mm at 500 meters
38 mm at 1,000 meters

looks like this baby fires ~70 freedoms per second

That's most morbid weapon with uranium amonition. People in Serbia know that very well !

Trust me, when one of those goes off overhead unexpectedly, you will poop yourself.

#4 Nope,that gun and plane were not even in service during the US involvement in Vietnam and were never nick-named Puff.
Here is the real Puff........

this the best fart sound there is

#7 Depleted uranium rounds are extremely weakly radioactive. Not enough to cause any kind of illness. It's the impact of extremely dense metal that you need to worry about, with a minimal side worry (for small bits of shrapnel) of heavy metal poisoning. It's used to bust through armor, not make people sick.

I'm happy knowing this is what is in the sky protecting my son.

#11 Depleted Uranium ammo is weakly radioactive but when you have thousands upon thousands of bullets hitting targets the aerosol or powder produced during impact can potentially contaminate wide areas around the impact sites. You can check out the medical reports from Fallujah, Iraq where the results of millions of depleted uranium shells are beginning to show in the form of birth deformations on a scale that is rising and has reached higher rates of cancer and leukemia than Hiroshima and Nagasaki had in 1945.

The only gun that comes automaticly with a plane

#11 I don't why know u had a couple thumbs down...
That is true what you said, unless American media is lying about it as well.
