When I was of high school age, I worked at a local airport fueling, washing, plowing the runway, etc. There was a real small twin engine plane that had to be jump started every once in awhile. The plug in to jump start it was along the nose of the aircraft about halfway between the tip of the nose and the leading edge of the wings. Once started you would have to hug the nose so you didn't come into contact with the prop as you walked back out towards the front of the aircraft. I think there was about 24+" between the nose and prop but it didn't feel like it once the engines fired up and that prop was roaring behind you. For whatever reason (I can't remember) you were never taught to come at the plug by crawling under the wing towards it and for whatever reason the manufacture put the plug at a horrible location. The only thing I can think of why they put it there was because the small nose was filled with aviation electronics, nose gear, batteries and maybe because the ice that slings off the prop and hits the nose could damage the plug in flap thingy. At least that's all I could come up with.
