My failure occurred when a young man "blew himself up" in NOLA, once upon a time. I had grabbed my FAK and when I got to him, burned over 95% of his body, I had not enough bandage material to even start.

I did manage to get his name and phone number to his next of kin by the time the ambulance arrived (and his lungs started frothing).

Yes, I felt totally inadequate.
