Who is the "Gupster"?
Me, apparently.
At far as guns go, I am 100% for them for self defense purposes. Every man has the right to defend his life and the lives of his family.
Now
that is entirely irrelevant not just to the thread, but to the forum, and to this web site.
As an emergency euthanasia implement in case the pilot catches fire, I would say that today the chances of this happening are low enough that the gun is not worth its own weight.
Chances? What's "chance" about inflight suicide?
Not only is this idiocy irrelevant and fanciful, but it has no place in a serious discussion among pilots, private or otherwise. Perhaps you'd be more comfortable publishing this tripe in the jetblast section.
