 DATE: After discovering the Japanese float plane, Robin is awakened  to the sound of Quinn sawing the floats off the plane. He is using  an apparently new hacksaw, which he did not bring with him. Did he  return to the crash site which was several miles away? Or did he  find one inside the float plane? If indeed it was inside the float  plane, the blade would have rusted through after 40 years in the  jungle.
