Do you know English?

I dunno if this is an old one..Got this as a fwd recently.. found it good...So try it if uve nt.

Can you decipher this into plain English and try to match it with another incident that all of us already know of?
A research team proceeded towards the apex of a natural geologic 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 descended, sustaining severe damage to the upper cranial portion of 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.
