I agree, as usual poor navigation was key to their entry to the world of survival. They took a sorta SW heading and drifted to the left of the course they wanted. Very basic GPS nav (Geko or basic eTrex) would have kept them on track. Once there they seemed to do well, kept their heads, did what needed to get done.
