how long is exactly the gau8 regarding to the plane’s dimensions?two thirds?

More like 1/3 – 36.5%

A-10 Thunderbolt:
“Length: 53 ft 4 in (16.26 m)”
http://en.wikipedia.org/wiki/A-10_Thunderbolt_II

GAU-8 Avenger:
“It measures 19 ft 5½ in (5.93 m) from the muzzle to the rearmost point of the ammunition system, and the ammunition drum alone is 34.5 inches (88 cm) in diameter and 71.5 inches (1.82 m) long.”

if you scroll down on this page, you can see that the gun with Ammo drum has about the size a VW beetle.

violent cough how big?!
gosh that’s enough to wipe out an entire battalion

That’s a very scary web site Alfred.

It is scary. The topic itself is very critical. I thnk nobody really thought of this type of “toxic waste” before.
Actually, Don, If you don’t feel comfortable haveing the link here. I can delete it.
I would also not mind, if you delete it.
It was just to show the comparison of the beetle to the Gun. It pops up in Google picture search if you look for A-10.
Again, if you want me to delete it, let me know.

Thanks for offering Alfred, but the link is not a problem.

More people should be aware of yet another consequence of violent conflict and the pictures and information are indeed helpful to understand the size of the GAU-8.

eh…a link…not such a big problem
are you scared by some pictures?there are a lot badder thing that you should be aware
