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.
When the Porsche blew the transaxle, there was unobtainium all over the track.
