Looking at the "photograph", I can't help but think F-117 - front looks very similar, perhaps with some form of shadowed condensation creating an illusion for the rear of the diamond? I note the text in the first image added by Senior Pilot says that it was "stationary" but it seems credible to me that the poachers, er, walkers have either got their story wrong or embellished it a bit. I mean, that's never happened before!
