protuberance, the purpose of their expedition being the procurement of
a sample of fluid Hydride of oxygen in a large vessel, the exact size
of which was unspecified. One member of the team precipitously

his anatomical structure; Subsequently the second member of the team
performed a self rotational translation oriented in the same direction
taken by the first team member.
