Word originated around Sport Car Racing in the North Texas area in the mid '70s. We referred to "cheater" sport car motors as having unobtainium parts that the average person could not get, but I like the way it is used in #1.

-Space rockets are mostly made of unobtainium.
-There are so many conflicts in Africa due to the presence of unobtainium in the ground.
-Your CNC machine will crash only when you machine this one piece of unobtainium. Of course, you do not have enough to make a new piece.
A piece of shitanium that got broken will magically turn into unobtainium if you look for a replacement (Thus making it extremely expensive, even if you found one)
