As horrifying as the idea seems, and by no means take this as an offer to step up and do so without a darned good reason, I think I would be able to. I took a lot of first aid training years ago, when I was involved in a mountain climbing club and in a local mountain rescue group. You learn to be self-sufficient, and to examine the situation you find yourself in and figure the way to survive.

There are quite a few stories of individuals having to make this kind of choice. Here is a link to a similar one, a boy stuck in an irrigation system on a farm:http://tinyurl.com/yg3kqqb This boy was lucky, in that the were able to reattach his arm. There were also stories about others operating heavy equipment who were trapped until they cut off an arm. It makes one wonder if perhaps tractors should be made to protect operators in the event of a rollover. Here's another, involving an Australian miner: http://tinyurl.com/yhpc42a

Nooooo. I don't think I could. No matter how bad the situation I couldn't handle it. I would faint from the though of doing it if I was stuck in a bad situation like that. Th thought of it is making me queasy right now!

I would honestly let myself die before amputating my own limb. The pain would probably give me a heart attack, or I would have such a severe panic attack it would end me.

Now if someone else was stuck and I had to cut their limb off, that I could do, don't ask me why because I do not know. The only thing that would bother me was their screams but having worked with people who are on deaths trail, I'm used to the screams, they aren't as hurtful as they used to me.

Interesting question!
