Two men are laying dead beside a cabin in the side of a mountain.
How did they die?
There are a few different ways of looking at this.
On the one hand, a cabin most assuredly is a part of a plane. Does this mean the two gentlemen died in the crash and were subsequently propelled into a configuration beside the cabin of the plane? No.
The cabin is described as "in the side of a mountain". This gives creedence to a landslide/falling rocks theory to the cause of death. Does this mean that the two died in a landslide and their pummelled bodies came to rest beside the cabin? No.
The only absolute, infallible answer to this riddle is that the two men died (as do all mammals) from not getting any oxygen to their brains.
