Dan,
I am not sure where the expression “unobtanium” originated. It may have been around for a long time, but that was the answer given by Mark Donahue in response to a question about what the frame of the Can-Am series Porsche 917-T10 was made from.
That would have been about 1972, so it somewhat dates my interest in cars.
