I think that the pads used to be in the centre of the 'race track' in the top left quater of the first photo on this thread orientated parallel to the track that runs from the camp towards the 9 oclock.
I also believe that the crash site is central top on the same photo, beyond where a large(ish) but isolated building can be seen.
It has been twenty years though, and A_A: you probably briefed me in the first place as to the location!
