I am not a bioligist, but the No Mans land you are refering to is real, but it is also a very thin area. I am not saying a broadhead could not slip inbetween the spine and the lung, but it would be a tight fit. Now if the hit is high and more towards the neck that is a different story, there is a pretty sizable area in there I could see a bullet or arrow passing through with no damage to the lungs, but if you are talking high and above the elbow, it is very narrow.
