Yep, I went so low on the CPL flight test that I had actually decided in my own mind that we were going to actually land in this field. The examiner said he would tell me when to go around. We must have been down to around 50-75 ft when he said 'go-around'. When I was an instructor I found a little field in the south of England that was actually used as a private strip. I had permission of the owner and would actually get my students to land much to thier shock and horror. Good lesson for them though.
