Which way does the Derelict/Juggernaut fly?

Hi all. I've been a frequent visitor to this site but have never taken part till now. So for my first topic I like to see what people think about this. Ever since I saw the first Alien movie I was always under the impression that the two prongs of the derelict on LV426 were the back of the ship and that the round cockpit was the bridge on the front. I don't know what it was that convinced me of that but it was just the impression I got from seeing it sitting on the surface and I have accepted that for many years. It's only recently that I've entertained the thought that it flies with the prongs facing forward like a Cylon fighter from Battlestar Galactica (remake) after reading some comments and seeing a Youtube animation that someone made of it flying this way. However, this just doesn't feel right to me IMO and from the few seconds of it flying in the trailers, I think my feeling that the prongs are the back of the ship may be right. But then again, I could still be wrong as I had always thought that the ship had crashed on LV426 and Ridley has recently stated that it landed there so I was wrong about that.
