Why would military misadventure be a bigger sensation than an encounter with a Yeti? If the latter was proven to be true I would be far more amazed than if it was just a military accident.
Military misadventure happens all the time. When I was growing up near a military base in Norfolk, Virginia, a family who was friends with ours had a blast of machine gun fire rip through their car while traveling with the mother, father, and baby inside. Luckily nobody was injured.
